Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Fig. 1 is a schematic view of the overall structure of a suspension platform stabilizing mechanism according to an embodiment of the present utility model, and fig. 2 is an enlarged view of a portion of fig. 1 a.

Referring to fig. 1 and 2, in order to solve the technical problems in the related art, an embodiment of the present utility model provides a suspension platform stabilizing mechanism 10, including: a clamp body 110, a clamp stabilizer 120, a distance monitor 130, and a first driver 140.

Specifically, in the embodiment of the present utility model, the suspension platform may be a suspension device for overhauling, installing, assembling or otherwise working on the high-altitude device. As a specific example, in the embodiment of the present utility model, maintenance of a blade of a wind turbine is described as a specific example.

It will be appreciated that wind turbines typically have a column (also commonly referred to as a tower or tower) that is erected on the ground and on which blades are mounted, which are propelled and rotated by the air flow during the air flow process, to thereby drive a generator connected to the shaft of the blades to generate electricity.

After the wind driven generator is operated for a period of time, the blades of the wind driven generator are required to be overhauled, and the suspension platform is lifted to a proper height through the cooperation of the suspension platform and the wind ropes to perform operation. Under the condition of windy, the suspension platform is easy to shake, so that the maintenance operation is difficult. In order to prevent the suspension platform from shaking due to blowing or the like, referring to fig. 1, in the embodiment of the present utility model, a clamping body 110 is provided at a side of the suspension platform facing/facing the tower body.

Specifically, in the embodiment of the present utility model, the clamping body 110 may be made of metal or alloy materials such as stainless steel, aluminum alloy, cast iron, etc., so that the clamping body 110 may be ensured to have sufficient strength.

It will be appreciated that the tower or drum is generally cylindrical or conical in configuration. Therefore, referring to fig. 1, in the embodiment of the present utility model, a concave structure may be disposed on a side of the clamping body 110 facing to/facing the tower body, so as to adapt to the structure of the tower body, and improve the clamping range and stability when clamping with the tower body. In a specific arrangement, referring to fig. 1, clamping body 110 may be a body comprising a body beam 111, a holding pole 117, and a support pole 118; wherein, in specific use, the side of the main body beam 111 facing away from the tower/tower body is connected with the suspension platform; both the holding pole 117 and the suspension are provided on the side of the body beam 111 facing the tower/tower. Wherein the holding pole 117 is inclined with respect to the body beam 111, and the support pole 118 is supported between the holding pole 117 and the body beam 111, thereby forming a stable triangle structure. Referring to fig. 1, in the embodiment of the present utility model, holding rods 117 and supporting rods 118 are provided at both ends of the main body beam 111, so that a concave structure in which one side of the clamping main body 110 facing the tower body can be matched with the tower body is provided, so that the clamping main body 110 can be conveniently matched with the peripheral wall of the tower body/tower barrel, and positioning is formed. Shaking of the suspension platform can be avoided.

It will also be appreciated that in general, the tower/drum of a wind turbine is designed to maintain stability and improve tensile strength, and the tower is usually designed to have a conical structure, i.e. a large bottom diameter and a small top diameter. In order to ensure that the clamping body 110 can form a better encircling clamping relationship with the tower body, in the embodiment of the utility model, a propping roller 119 is arranged on one side of the clamping body 110 facing the tower body. Referring to fig. 1, in the embodiment of the present utility model, a plurality of abutment rollers 119 may be provided, and the plurality of abutment rollers 119 may be arranged along the circumferential direction of the concave structure (may be understood as the circumferential direction of the tower body in specific use). As a specific example, referring to fig. 1, in the embodiment of the present utility model, four abutment rollers 119 may be provided, and the four abutment rollers 119 are symmetrically disposed along the central axis i of the clamping body 110, so that, in the lower section of the tower body, the clamping body 110 may be two abutment rollers 119 located at the outer side and abut against the peripheral wall of the tower body, thereby stabilizing the suspension platform. In the process of gradual construction operation, the suspension platform moves upwards along the tower body, and the propping roller 119 can reduce/reduce the friction between the clamping main body 110 and the tower body, so that the anti-corrosion layer on the surface of the tower body can be well protected. After the suspension platform is lifted to the upper section of the tower body, the overall diameter of the tower body is reduced at this time, the two propping rollers 119 positioned at the outer side can not be matched with the tower body for propping, and at this time, the two propping rollers 119 positioned at the inner side can be in holding contact with the peripheral wall of the tower body, so that the suspension platform is stabilized.

Referring to fig. 1, in the embodiment of the present utility model, the grip stabilizer 120 is connected to both ends of the grip body 110. In other words, the grip stabilizer 120 is provided in two, one of the two grip stabilizers 120 is provided at one end of the grip main body 110, and the other of the two grip stabilizers 120 is provided at the other end of the grip main body 110. In a specific arrangement, as shown with reference to fig. 1 and 2, the clamp stabilizer 120 may be movably connected to the holding pole 117.

In the embodiment of the present utility model, it should be noted that the movable connection manner of the clamping stabilizer 120 and the holding pole 117 may be specifically a rotational connection, for example, the clamping stabilizer 120 is rotationally connected with the end of the holding pole 117 through a structure such as a rotating shaft and the first shaft hole 112; in addition, the rotational direction of the grip stabilizer 120 may be a circumferential wall facing or facing away from the tower. That is, the rotational surface of the grip stabilizer 120 may be identical to the radial cross section of the tower. Alternatively, when the suspension platform is specifically used, the suspension platform extends outward along the radial direction of the tower body, so that the rotation surface of the clamping stabilizer 120 may be identical to the plane on which the suspension platform is located. Here, the fact that the rotation surface of the grip stabilizer 120 coincides with the radial cross section of the tower body may mean that the rotation surface of the grip stabilizer 120 is parallel or approximately parallel to the radial cross section of the tower body.

In some possible examples of the embodiment of the present utility model, the gripping stabilizer 120 may be movably connected to the holding pole 117 in other manners, for example, the gripping stabilizer 120 may be connected to the holding pole 117 in a sliding telescopic manner, and specifically, the sliding telescopic direction of the gripping stabilizer 120 may be consistent with the radial direction of the tower body.

Referring to fig. 1 and 2, in an embodiment of the present utility model, the first driving member 140 may be disposed at a side of the grip stabilizer 120 facing the grip body 110. In a specific arrangement, referring to fig. 1 and 2, the first driving member 140 may be specifically disposed at an end of the body beam 111, and the other end of the first driving member 140 is connected to the clip stabilizer 120. Here, the other end of the first driving member 140 may be directly connected to the grip stabilizer 120 or indirectly connected to the grip stabilizer.

It is understood that the first driver 140 may be an electric cylinder, a gas cylinder, a piston cylinder, etc., and in some possible examples, the first driver 140 may also be an electric push rod.

In the embodiment of the present utility model, the first driving member 140 drives the clamping stabilizer 120. Like this, when concrete use, when suspension platform need go up and down, can drive the clamp stabilization spare 120 through first driving piece 140 and move (for example, refer to the direction that the arrow x shows in the figure 2 in the clamp stabilization spare 120 can be driven to the first driving piece 140) dorsad barrel motion to make clamp stabilization spare 120 and tower body contactless, the oscilaltion of suspension platform of being convenient for, and clamp stabilization spare 120 can not cause the damage to the tower body, can effectively protect the tower body. In addition, when the suspension platform is moved to a proper position (for example, to a position requiring maintenance), the first driving member 140 may drive the clamping stabilizer 120 to move toward the tower body (for example, as shown in fig. 2, the first driving member 140 may drive the clamping stabilizer 120 to move in a direction indicated by an arrow y in fig. 2), so that the clamping stabilizer 120 may be clasped on a peripheral wall of the tower body and form a support for the clamping body 110. I.e. the contact area or the holding point of the suspension platform stabilizing mechanism 10 and the tower body can be increased, thereby improving the stability of the suspension platform stabilizing mechanism 10.

It can be appreciated that, in the process of driving the clamping stabilizer 120 to the tower body by the first driving member 140, the first driving member 140 may have a large pushing force, so that the clamping stabilizer 120 may impact the tower body and be damaged; in addition, in the process of driving the clamping stabilizer 120 to move toward the tower body, the first driving member 140 may have a larger movement distance of the clamping stabilizer 120, so that a force between the clamping stabilizer 120 and the circumferential wall of the tower body becomes a main force, and thus the abutment roller 119 may be pushed away from the circumferential wall of the tower body, resulting in a reduction in contact points between the suspension platform and the circumferential wall of the tower body, which is unfavorable for the stability of the suspension platform.

Referring to fig. 2, in an embodiment of the present utility model, a distance monitor 130 is provided on the grip stabilizer 120. In particular, in an embodiment of the present utility model, the distance monitor 130 may be a distance monitor or a distance measurement switch. In some specific examples, the distance monitor 130 may be a pressure-responsive contact switch, which may be specifically disposed on a side of the grip stabilizer 120 facing the tower. In the process that the first driving member 140 drives the clamping stabilizer 120 to move towards the tower body, the clamping stabilizer 120 contacts with the peripheral wall of the tower body, and the contact switch is triggered, so that the first driving member 140 stops driving the clamping stabilizer 120, damage to the peripheral wall of the tower body caused by overlarge pressure of the clamping stabilizer 120 can be effectively avoided, and in addition, the situation that the supporting roller 119 is pushed away from the tower body due to excessive movement of the clamping stabilizer 120 can be avoided.

In another alternative example of the embodiment of the present utility model, the distance monitor 130 may also be a non-contact switch, for example, in some examples, the distance monitor 130 may be a photo-sensor, in a process that the first driving member 140 drives the clamping stabilizer 120 to move towards the tower body, the distance between the clamping stabilizer 120 and the tower body is gradually reduced, the light intensity that the distance monitor 130 may receive is gradually reduced, when the light intensity is less than or equal to a preset threshold value, or when the distance between the clamping stabilizer 120 and the tower body is less than or equal to a preset distance, the distance monitor 130 triggers to generate an induction signal, and the first driving member 140 may stop driving the clamping stabilizer 120 to move towards the tower body according to the induction signal, so as to avoid occurrence of collision between the clamping stabilizer 120 and the tower body, and thus, an effective protection effect on the tower body can be achieved.

As a specific example of the embodiment of the present utility model, the distance monitor 130 may be a magnetic distance monitor 130, for example, the distance monitor 130 may be a hall switch, and in a process that the first driving member 140 drives the clamping stabilizer 120 to move toward the tower body, a magnetic field in the hall switch is cut by the tower body to generate an induction signal, so that the first driving member 140 stops driving the clamping stabilizer 120, and a preset distance is kept between the clamping stabilizer 120 and the tower body. Here, the preset interval may be specifically 5cm to 8cm. In some specific examples, the preset spacing may specifically be 5cm, 6cm, 7cm, 8cm, or the like. It should be understood that, in the embodiment of the present utility model, specific values of the preset pitches are only shown as some specific examples, and in some other examples of the embodiment of the present utility model, the preset pitches may also be other values, which are not listed in the embodiment of the present utility model.

It should be noted that, the numerical values and the numerical ranges related to the embodiments of the present utility model are approximate values, and may have a certain range of errors under the influence of the manufacturing process, and those errors may be considered to be negligible by those skilled in the art.

According to the suspension platform stabilizing mechanism 10 provided by the embodiment of the utility model, the clamping stabilizing pieces 120 are arranged at the two ends of the clamping main body 110, and the distance monitors 130 are arranged on the clamping stabilizing pieces 120, so that when the clamping main body 110 is surrounded on the peripheral wall of the tower body, the first driving piece 140 drives the clamping stabilizing pieces 120 to move towards the peripheral wall of the tower body, and when the distance monitors detect that the distance between the clamping stabilizing pieces 120 and the peripheral wall of the tower body is smaller than or equal to the preset distance, the first driving piece 140 can stop driving the clamping stabilizing pieces 120 to move continuously according to the induction signals generated by the distance monitors 130, thereby effectively avoiding the collision between the clamping stabilizing pieces 120 and the peripheral wall of the tower body, effectively avoiding damage to the peripheral wall of the tower body caused by the clamping stabilizing pieces 120, effectively protecting the anticorrosive coating of the tower body, and improving the protection to the tower body.

With continued reference to fig. 1 and 2, in an alternative example of an embodiment of the present utility model, the suspended platform stabilizing mechanism 10 further includes a first link 150, one end of the first link 150 is rotatably connected to the clamping body 110, and the other end of the first link 150 is rotatably connected to the clamping stabilizer 120.

Specifically, in the embodiment of the present utility model, the first link 150 may be made of the same or similar material as the clamping body 110. First link 150 may be specifically rotatably coupled to holding pole 117 when specifically configured.

Referring to fig. 1 and 2, in the embodiment of the present utility model, the first driving member 140 is connected to the first link 150, so that the first driving member 140 can drive the movement of the grip stabilizer 120 by driving the first link 150.

As a specific example, referring to fig. 1 and 2, the first driving member 140 may be an electric push rod, and the first driving member 140 may be connected to the first link 150 in a rotatable connection. In this way, a multi-link structure is formed between the first driving member 140, the first link 150, the holding rod 117 and the support rod 118, so that the first driving member 140 can stably drive the first link 150. In a specific arrangement, referring to fig. 2, the first driving member 140 may be connected to a middle portion of the first link 150, and of course, in other alternative examples of the embodiment of the present utility model, the first driving member 140 may be connected to an end of the first link 150 opposite to the holding rod 117, so that a force required for driving the first link 150 by the first driving member 140 can be reduced.

In the embodiment of the present utility model, the end of the first connecting rod 150 facing away from the holding pole 117 is rotatably connected to the holding stabilizer 120, and it can be understood that the connection between the first connecting rod and the holding stabilizer 120 may be performed by a structure such as a rotating shaft, a first shaft hole 112, etc. In a specific arrangement, referring to fig. 2, a second link 121 may be disposed at an end of the first link 150 facing away from the holding rod 117, wherein the extending direction of the second link 121 may be different from that of the first link 150, and specifically, the extending direction of the second link 121 may extend toward/toward the inside of the concave structure of the clamping body 110, that is, the two second links 121 at both ends of the clamping body 110 may specifically extend toward each other. As a specific example, the extending direction of the second link 121 may be perpendicular or approximately perpendicular to the first link 150. The grip stabilizer 120 may be rotatably connected to the second link 121.

In the embodiment of the present utility model, the clamping stabilizer 120 is connected to the first link 150, and in addition, the clamping stabilizer 120 is rotatably connected to the first link 150. Thus, when the first driving member 140 drives the first link 150, the grip stabilizer 120 moves toward/toward the tower body, the grip stabilizer 120 is positioned at a side facing the tower body, and when the distance monitor 130 detects that the distance between the grip stabilizer 120 and the tower body is less than or equal to the preset distance, the first driving member 140 stops driving the grip stabilizer 120. In maintenance operation, because reasons such as wind blows, the suspension platform probably has slight rocking, and the centre gripping stabilizer 120 probably contacts with the tower body this moment, owing to centre gripping stabilizer 120 sets up to be rotatable coupling with first connecting rod 150, and after centre gripping stabilizer 120 contacted with the tower body, can rotate according to the cambered surface shape adaptability of tower body, be soft contact with the contact of tower body week wall to can effectively avoid causing the condition of scratch to the tower body week wall, can effectively protect the anticorrosive coating of tower body week wall.

Fig. 3 is a cross-sectional view of a connection between a first link and a clamping body in a suspension platform stabilizing mechanism according to an embodiment of the present utility model.

Referring to fig. 3, in an alternative example of the embodiment of the present utility model, a first shaft hole 112 is formed on a first link 150, a pin 113 is inserted into the first shaft hole 112, and a first damping member 114 is sleeved on the outer circumference of the pin 113; the first link 150 is in damped connection with the clamping body 110.

In some specific examples, the first shaft hole 112 may be provided on the first link 150, and referring to fig. 3, an end of the holding rod 117 may be provided with a transfer lug 1171, a through hole may be provided on the transfer lug 171 at a position corresponding to the first shaft hole 112, and the pin 113 may penetrate through the through hole and the first shaft hole 112. The pin 113 may be made of high-strength steel. The first damping member 114 may be a damping member made of nylon material, for example, a damping sleeve. When specifically arranged, the first damping member 114 may be sleeved on the outer periphery of the pin 113 and abuts against the inner wall of the first shaft hole 112.

Like this, the pore wall of first shaft hole 112 and some burrs or rough surfaces that exist on the perisporium of round pin axle 113 can form intermeshing's relation with first damping piece 114 between, can promote the rotation resistance between first connecting rod 150 and the holding pole 117 to a certain extent, can effectively avoid after the sensor signal is sent from monitor 130, first connecting rod 150 can effectively avoid the collision condition between centre gripping stabilizer 120 and the tower body because of inertial mechanical movement's condition, can play effectual guard action to the tower body.

With continued reference to FIG. 3, in alternative examples of embodiments of the present utility model, a second damping element 116 is provided between the adapter ear 1171 and the first link 150.

Specifically, as described with reference to fig. 3, the second damping element 116 is disposed between the adapter lug 1171 and the first connecting rod 150, and specifically, the second damping element 116 may be in a ring shape and sleeved on the pin 113. In an embodiment of the present utility model, the second damping member 116 may be made of the same material as the first damping member 114, for example, nylon materials.

In addition, by providing the buffer block 160 at one side of the grip stabilizer 120 facing the tower body, thus, when the grip stabilizer 120 contacts with the peripheral wall of the tower body, the buffer block 160 can provide a sufficient friction force to support the grip stabilizer 120 and the grip main body 110 connected with the grip stabilizer 120, thereby ensuring the overall stability of the suspension platform and effectively avoiding the shaking of the suspension platform.

In a specific example of the embodiment of the present utility model, the buffer blocks 160 include two, and the two buffer blocks 160 are arranged along the extending direction of the grip stabilizer 120.

Thus, the two buffer blocks 160 can respectively protect the edges and corners of the two ends of the clamping stabilizer 120, so as to avoid damage to the peripheral wall of the tower body caused by the edges and corners of the ends of the clamping stabilizer 120.

As a specific example of an embodiment of the present utility model, referring to fig. 2, a buffer block 160 is rotatably coupled to the grip stabilizer 120.

Specifically, the buffer block 160 and the clamping stabilizer 120 may be rotatably connected by a structure such as a rotation shaft, a first shaft hole 112, or a shaft pin.

Thus, when the swing angle control member 30 is extended and contracted, for example, as illustrated in fig. 4, the position of the clamping body 110 is not moved when the length of the swing angle control member 30 is extended, the cantilever 20 can swing in the direction indicated by the arrow x in fig. 4, so as to adjust the swing angle of the cantilever 20, thereby facilitating maintenance of the entire blade of the wind turbine. In addition, in some examples, as the length of the yaw angle control member 30 is shortened, the cantilever 20 swings in a direction indicated by an arrow y in fig. 4, thereby adjusting the swing angle of the cantilever 20 in the opposite direction.

In the embodiment of the utility model, the electric cylinder, the electric push rod, the air cylinder, the oil hydraulic cylinder or the piston cylinder and the like are adopted as the swing angle control member 30, so that the torque required for swinging the cantilever 20 or adjusting the swing angle of the cantilever 20 can be reduced, the requirement on the first driving member 140 can be reduced, and the processing production cost is saved.

It will be appreciated that the blades of a wind turbine are typically at an oblique angle to the tower, i.e. typically the blades are inclined relative to the vertical; thus, in the height direction, the distance between each part of the blade and the tower is different, and the length of the cantilever 20 needs to be adjusted so as to overhaul different positions of the blade. Referring to fig. 8 and 9, in an embodiment of the present utility model, the boom 20 may be a telescopic boom.

Of course, it will be appreciated that the telescopic joint 220 may also be slid in a direction opposite to the direction shown by arrow x in fig. 8, thereby shortening the length of the entire cantilever 20.

In a specific setting, in an embodiment of the present utility model, the length of each expansion joint 220 may be manufactured to be a standard length according to a certain manufacturing specification, for example, the length of each expansion joint 220 is set to be 4m, 5m, or 6 m. In this way, production and processing of each expansion joint 220 is facilitated.

Referring to fig. 9, in the embodiment of the present utility model, during the process of the suspension platform cantilever 20 being extended or the cantilever 20 being extended, there is a certain stress between the expansion joint 220 located at the middle and the end and other expansion joints 220 under the action of gravity, or a certain deformation of the expansion joint 220 under the action of gravity.

Because of the stress between the expansion joints 220 or the deformation of the expansion joints 220, when the expansion joints 220 slide relatively, the friction effect between the expansion joints 220 is obvious in the stress concentration area or the deformation area, or the friction force is large, so that the situation of sliding and clamping (commonly referred to as holding force) is easy to occur; when the first driving member 140 is driven, it is required to overcome the friction force, which may cause abrupt sliding between the expansion joints 220, thereby generating resonance.

Wherein the fixing beam 510 may be fixed to the front end of the first expansion joint 221. It will be understood herein that, referring to fig. 11, the front end of the first telescopic joint 221 may specifically refer to one end in the sliding out or sliding in direction (i.e., the telescopic direction) of the second telescopic joint 222; in some examples, the front end of the first telescopic joint 221 may also be understood as the open end of the first telescopic joint 221 when the second telescopic joint 222 0 is inserted into the first telescopic joint 221.

In the embodiment of the present utility model, the fixing beam 510 may be specifically connected to the first expansion joint 221 through a connection fixing member such as a bolt, a screw, or a nut.

Specifically, in the embodiment of the present utility model, the sliding block 520 may be fixedly connected to the fixed beam 510. For example, in some examples, a counterbore may be formed in the slider 520, and a connecting member such as a screw, bolt, or screw may be inserted through the counterbore to be fixed to the fixed beam 510. In some alternative examples of the embodiment of the present utility model, the sliding block 520 may also be connected to the fixed beam 510 by using a clamping manner, for example, in some examples, a clamping groove may be formed on a side of the fixed beam 510 facing the second expansion joint 222, and a portion of the sliding block 520 is embedded into the clamping groove by using an interference fit manner, so as to connect the sliding block 520 to the fixed beam 510.

In particular use, after the second expansion joint 222 is inserted into the first expansion joint 221, the sliding block 520 may abut against the sliding beam of the second expansion joint 222, so as to facilitate the sliding of the second expansion joint 222 relative to the first expansion joint 221.

As a specific example, in the embodiment of the present utility model, the telescopic arm is telescopic in the horizontal or approximately horizontal direction as an example. The slider 520 may be disposed above or on top of the second expansion joint 222. When the telescopic arm is stretched, because a certain stress exists at the connection position of the second telescopic joint 222 stretching with the first telescopic joint 221 under the action of gravity, in the embodiment of the utility model, the sliding block 520 is arranged above or on the top wall of the second telescopic joint 222, so that friction caused by the stress can be effectively reduced, and smoothness of the second telescopic joint 222 sliding relative to the first telescopic joint 221 is facilitated.

Fig. 12 is a schematic structural view of a slider in a suspension platform according to an embodiment of the present utility model.

Referring to fig. 12, in an alternative example of the embodiment of the present utility model, a side of the sliding block 520 facing the second expansion joint 222 is provided with a receiving groove 521, and the receiving groove 521 is adapted to receive a lubricant.

Specifically, in the embodiment of the present utility model, the accommodating groove 521 may be integrally formed with the sliding block 520.

It will be appreciated that in alternative examples of embodiments of the utility model, the receiving groove 521 may be formed by a secondary machining of the surface of the slider 520. For example, after the slider 520 is molded and cured, one of the surfaces of the slider 520 may be grooved or hollowed by a machining tool such as a lathe, a milling cutter, or the like, thereby forming the accommodating groove 521. In addition, in some alternative examples, the receiving groove 521 may be formed on one of the surfaces of the slider 520 by etching, laser engraving, or the like. When the slider 520 is connected to the fixed beam 510, the side having the accommodation groove 521 is installed facing the second expansion joint 222.

In the embodiment of the present utility model, the accommodating groove 521 may accommodate or place therein a lubricant, which may be, as a specific example, a lubricating grease, which may be filled in the accommodating groove 521. In a specific arrangement, the sliding block 520 may be connected to the fixed beam 510 after the lubricant is filled in the accommodating groove 521. It should be noted that the lubricating grease needs to be grease which is not corrosive to the plastic parts, for example, the lubricating grease can be silicon-based grease. In other examples of embodiments of the utility model, the lubricant may also be a graphite block, the graphite block being embedded within the receiving slot 521, and portions of the graphite block protruding out of the receiving slot 521.

In the embodiment of the present utility model, the accommodating groove 521 is disposed on the sliding block 520, when the sliding block 520 is mounted on the fixed beam 510, the accommodating groove 521 faces to/faces the sliding beam of the second expansion joint 222, so that the lubricant filled in the accommodating groove 521 can contact with the sliding beam of the second expansion joint 222 to perform a lubrication function, thereby effectively reducing the friction force between the sliding block 520 and the sliding beam of the second expansion joint 222, avoiding the occurrence of a jamming condition/phenomenon between the sliding block and the sliding beam after long-term friction, and effectively prolonging the service life of the telescopic arm.

With continued reference to fig. 12, in an alternative example of the embodiment of the present utility model, the accommodation grooves 521 are arranged at intervals along the sliding direction of the second expansion joint 222, and the plurality of accommodation grooves 521 arranged at intervals communicate with each other.

Specifically, taking fig. 11 and 12 as specific examples, generally, the second expansion joint 222 may be inserted into the first expansion joint 221 and slide along the length direction of the first expansion joint 221 (or the length direction of the second expansion joint 222), specifically may slide along the direction indicated by the arrow x in fig. 12 (taking the stretching process as an example), or, in some examples, the sliding direction of the second expansion joint 222 may also slide along the direction opposite to the direction indicated by the arrow x in fig. 12 (taking the shortening process as an example). In the embodiment of the present utility model, the plurality of receiving grooves 521 may be arranged along the sliding direction of the second expansion joint 222. For example, the direction shown in fig. 12 is taken as an example, wherein the direction shown by the arrow x may be the sliding direction of the slider 520 with respect to the sliding beam (i.e., the sliding direction of the second expansion joint 222), the direction shown by the arrow y may be the width direction of the slider 520 (i.e., the width direction of the sliding beam), and the direction shown by the arrow z may be the thickness direction of the slider 520.

In a specific arrangement, referring to fig. 12, in the embodiment of the present utility model, the accommodating groove 521 may be a bar-shaped groove, and the extending direction of the bar-shaped groove may specifically extend along the width direction of the sliding block 520, that is, the length direction of the bar-shaped groove may be the same, similar or identical to the direction shown in the y direction in fig. 12. Thus, the length direction in the bar-shaped groove can cover the width of the sliding beam, so that the lubricant can be arranged in the width direction of the sliding beam, and the lubricating effect between the sliding beam and the sliding block 520 can be improved.

In addition, referring to fig. 12, in the embodiment of the present utility model, a plurality of receiving grooves 521 are communicated with each other. For example, as shown in fig. 12, a groove along the sliding direction of the slider 520 may be provided at a side of the slider 520 having the receiving groove 521, and the groove sequentially passes through the plurality of receiving grooves 521, thereby communicating the plurality of receiving grooves 521. In some examples, perforations or through holes may be provided in the direction shown by x in fig. 12, the perforations or through holes communicating with the plurality of receiving slots 521. In this way, the lubricants in the plurality of receiving grooves 521 are facilitated to flow each other between the receiving grooves 521, thereby improving the uniformly distributed area of the lubricants on the surface of the slider 520 and improving the lubrication effect of the lubricants between the slider 520 and the sliding beam.

In the embodiment of the present utility model, a plurality of accommodating grooves 521 are arranged at intervals on a side of the sliding block 520 facing the sliding beam, and the accommodating grooves 521 are arranged at intervals along the sliding direction of the second telescopic member. Thus, the lubricant in the accommodating groove 521 can be uniformly distributed between the sliding block 520 and the sliding beam, and the lubrication effect can be effectively improved. In addition, the plurality of receiving grooves 521 are communicated with each other, so that the lubricants in the plurality of receiving grooves 521 flow between the receiving grooves 521, thereby increasing the uniformly distributed area of the lubricants on the surface of the sliding block 520, and increasing the lubrication of the sliding block 520 and the sliding beam by the lubricants. The friction force between the sliding block 520 and the sliding beam of the second telescopic joint 222 telescopic joint 220 can be effectively reduced, the situation/phenomenon that the sliding block and the sliding beam are blocked after long-term friction is avoided, and the service life of the telescopic arm is effectively prolonged.

With continued reference to fig. 10-12, in an alternative example of an embodiment of the utility model, slider 520 includes a first side wall 522 and a second side wall 523, where first side wall 522 abuts the top wall of the slide beam and second side wall 523 abuts the side wall of the slide beam.

Specifically, referring to fig. 12, in an embodiment of the present utility model, the first sidewall 522 and the second sidewall 523 may not be parallel. When specifically provided, the angle and shape between the first and second side walls 522 and 523 may be provided according to the specific shape of the sliding beam. As a specific example of the embodiment of the present utility model, referring to fig. 12, the specific shape of the slider 520 may be set to be an "L" shape, so that a portion of the "L" shape may collide against the top wall of the sliding beam and another portion may collide against the side wall of the sliding beam.

In the embodiment of the present utility model, the sliding block 520 is provided in two parts, namely, a first side wall 522 and a second side wall 523, wherein the first side wall 522 abuts against the top wall of the sliding beam, and the second side wall 523 abuts against the side wall of the sliding beam. In this way, in the event of failure of the sliding wheel between the side/wall of the first telescopic joint 221 and the second telescopic joint 222, the second wall 523 of the sliding block 520 can still perform a certain lubrication function, which can extend the service life or the service life of the telescopic arm. When faults occur in the overhaul process, the overhaul operation can be completed at least once, and the operation efficiency of the overhaul operation can be improved.

In the embodiment of the present utility model, the positioning portion 224 is disposed on one of the two adjacent expansion joints 220, and the limiting mechanism 70 is disposed on the top of one of the two adjacent expansion joints 220; in this way, in the process of mutual sliding and telescoping of the telescopic joints 220, part of the telescopic joints 220 which are frequently worn can be positioned, so that the telescopic joints 220 which are not frequently slid can be opened in a sliding manner, and the uniform wear degree of all the telescopic joints 220 is ensured.

When the limiting member 720 slides to the positioning portion 224, the elastic member 730 pushes the limiting member 720 to extend into the positioning portion 224, so as to position the two telescopic joints 220 that slide relatively.

As an alternative example of the embodiment of the present utility model, referring to fig. 19, the end of the stopper 720 may be provided in a wedge structure, wherein the inclined surface 721 of the wedge structure faces in a direction when the adjacent two expansion joints 220 contract with each other. Thus, when the second driving member 610 drives the telescopic joint 220 to be contracted, the contraction of the telescopic joint 220 can be facilitated.

It will be appreciated that in embodiments of the present utility model, the size of the opening of the stop collar 840 may be smaller than the radial size of the tensioner 820. Like this, the spacing ring 840 can play the effect of drawing in or gathering together to the direction that draws in each other to wind rope 830 around setting up on take-up pulley 820, can effectively increase the wrap angle between wind rope 830 and take-up pulley 820 to increase the frictional force of take-up pulley 820 to wind rope 830, guaranteed the tensioning effect to wind rope 830.

It will also be appreciated that in the embodiment of the present utility model described with reference to fig. 21 and 22, the wind rope tensioning mechanism 80 further includes a protective housing 850, and the protective housing 850 covers a side of the tensioning wheel 820 facing away from the third driving member 810. When specifically provided, the side of the protective shell 850 facing the stop collar 840 has an opening.

It is understood that as a specific example of an embodiment of the present utility model, the angle monitoring sensor may be a level gauge, a gyroscope, or a level ball.

As a specific example, in the embodiment of the present utility model, after receiving the inclination angle sent by the angle monitoring sensor, the PLC may compare the inclination angle with a preset inclination angle threshold, so as to determine whether to send a control signal to adjust the basket 90. When specifically set, the preset inclination angle threshold may be set to be ±14° with respect to the horizontal direction; in the case that the angle transmitted by the angle monitoring sensor exceeds the preset angle threshold, the PLC adjusts the angle of the basket body 90, thereby ensuring that the inclination angle of the basket body 90 is within the preset angle threshold range, i.e., maintaining the basket body 90 horizontal or approximately horizontal.
