Please refer to a scene diagram of manually hoisting heavy objects shown in fig. 1, which takes an antenna as an example of a material to be hoisted, and assume that a preset hoisting height is a height of an iron tower 50 meters away from the ground. The manual hoisting method at least needs 5 persons (A, B, C, D, E5 persons are needed in fig. 1) for 1 hour to complete the hoisting of the antenna on one side. In the figure, a assists B, C, D in pulling a lifting rope (such as the rope indicated by "1" in fig. 1) at a predetermined height above the tower, and a releases the antenna from the pulling rope (such as the rope indicated by "2" in fig. 1) when the antenna rises to the predetermined height; B. c, D providing a pulling force on one side of the tower to raise the antenna to a predetermined height; and E, controlling a traction rope on the other side of the iron tower to avoid collision between the antenna and the iron tower.

If adopt above-mentioned artifical hoist and mount's mode, it is more time-consuming and laboursome, have great potential safety hazard moreover. If the B, C, D is loose, the antenna may be dropped and damaged by the fall. Therefore, a winch is generally adopted for hoisting in the current hoisting process. The hoist is also called a winch, and is a device for hoisting or pulling a heavy object by winding a wire or a chain around a drum, and the hoist can hoist or pull the heavy object vertically, horizontally or obliquely by winding a wire around the drum.

Fig. 2 provides a scene diagram of hoisting by a winch. Referring to fig. 2, 3 persons (A, B, C3 persons are needed in fig. 2) are needed to finish hoisting by using a hoisting machine. The winch can be fixed at the position (A in figure 2) of the tower bottom at one side, and A controls the winch by a switch near the winch; b, controlling a traction rope on the other side of the iron tower to avoid collision between the antenna and the iron tower; and C, releasing the antenna from the traction rope when the antenna rises to a preset height on the iron tower at the preset height. The manpower can be saved by adopting the winch to hoist heavy objects.

Fig. 3 provides a schematic structural diagram of a conventional winch applied to the hoisting scenario shown in fig. 2, and the winch includes a motor (01), a transmission device (02), two couplers (03), and a working machine (04). One end of the transmission device (02) is connected with the motor (01) through a coupling (03), and the other end of the transmission device is connected with the working machine (04) through the coupling (03). When the winch works, the motor (01) drives the transmission device (03) to rotate through the coupler (03), and the transmission device (03) drives the working machine (04) to rotate through the coupler (03), so that the heavy object is lifted.

In the working process of the winch shown in fig. 3, the coiled traction rope is easy to wind and knot in high-speed movement, so that the hoisting efficiency is influenced. In view of this, the present application provides a winch, and specifically, refer to fig. 4, 5 and 6, which are three-angle perspective views of the winch. This hoist engine includes: the anti-falling device comprises a fixed base (1), a driving motor (2), a control unit (3), a reel (4), a rope guide mechanism (5), an anti-falling device (6), a power supply (7) and a foot switch (8).

Referring to fig. 4 and 5, the fixing base (1) includes a first base (11), a second base (12) and at least two adjusting screws (10). The first base (11) and the second base (12) may include a top plate, a bottom plate, and side plates. The top plate is fixedly connected with the side plate, the side plate is fixedly connected with the bottom plate, and the top plate and the bottom plate are arranged oppositely. One end of the adjusting screw rod (10) is fixedly connected with the inner surface of the side plate of the first base (11), the adjusting screw rod (10) penetrates through the side plate of the second base (12) and is movably connected with the side plate of the second base (12), and the adjusting screw rod (10) is used for adjusting the distance between the first base (11) and the second base (12). The inner surface of the side plate of the first base (11) refers to the surface of one side of the side plate of the first base (11) close to the second base (12), and the outer surface of the side plate of the first base (11) refers to the surface of one side of the side plate of the first base (11) far away from the second base.

Further, referring to fig. 5, a top plate and a bottom plate of the first base (11) are provided with a first card slot (110), and a top plate and a bottom plate of the second base (12) are provided with a second card slot (120). The first clamping groove (110) and the second clamping groove (120) are arranged in opposite directions, and the adjusting screw (10) is used for adjusting the distance between the first clamping groove (110) and the second clamping groove (120). The distance between the first clamping groove (110) and the second clamping groove (120) can be adjusted through the adjusting screw (10), so that objects in various shapes and sizes can be clamped in the first clamping groove (110) and the second clamping groove (120). The shapes of the first card slot (110) and the second card slot (120) are not limited. For example, the first slot (110) and the second slot (120) may be triangular, so that cylinders with various shapes and sizes can be effectively clamped. The depths of the first clamping groove (110) and the second clamping groove (120) are not limited, and can be customized according to the size of a cylinder to be clamped.

It should be noted that the top plate and the bottom plate of the first base (11), and the top plate and the bottom plate of the second base may also be provided with other numbers of slots, as long as the column can be clamped in the slots, and this is not limited here. For example, in other embodiments, a clamping groove may be provided only on the top plate of the first base (11) and not on the top plate of the second base (12), and the first base (11) and the second base (12) may be clamped with cylinders of various shapes by adjusting the adjusting screw (10); or two clamping grooves are arranged on the first base (11), one clamping groove is arranged on the second base, and the adjusting screw rod can be adjusted, so that the first base (11) and the second base (12) are clamped with cylinders in various shapes and sizes.

It should be noted that if the shapes of the clamping grooves formed in the bottom plate and the top plate are different, the clamping groove in the top plate can clamp the column body, and the clamping groove in the bottom plate is not clamped, so that the clamping groove formed in the bottom plate does not play a role. Therefore, the bottom plate of the first base (11) needs to be provided with a clamping groove with the same shape as the top plate of the first base (11), and the bottom plate of the second base (12) needs to be provided with a clamping groove with the same shape as the top plate of the second base (12). So that the top plate and the bottom plate can clamp the columns with the same shape and size.

Referring to fig. 4, the driving motor (2) is disposed on the fixed base (1), and specifically, the driving motor (2) is disposed on an outer surface of a side plate of the first base (11). The manner of fixedly connecting the driving motor (2) and the first base (11) is not limited, and welding, riveting or the like may be used. The driving motor (2) is in driving connection with the reel (4), and the driving motor (2) is used for driving the reel (4) to rotate. Illustratively, the driving motor (2) can be connected with the reel (4) through a shaft coupling.

The control unit (3) is used for controlling the working state of the driving motor (2). For example, the operation state of the driving motor may include a direction in which the driving motor (2) drives the reel (4) to rotate, a speed of the rotation, and the like, which is not limited herein. The control unit (3) can be a chip or a circuit board and the like and is arranged in the driving motor (2); the control unit (3) can also be an independent structure and is mutually independent from the driving motor (2), and the control unit (3) is electrically connected with the driving motor (2). The control unit (2) can control the working state of the driving motor (2) according to a preset program code or a preset circuit structure. The control unit (3) can be provided with a control panel, and the rotating direction and the rotating speed of the driving motor (2) can be set or the driving motor can be controlled to start or stop through operation on the control panel; the control unit (3) can also be provided with a remote control switch, and the wireless signal of the remote control switch is received so as to set the rotating direction and the rotating speed of the driving motor (2) or control the driving motor to start or stop.

Further, referring to fig. 5, the winding shaft (4) may further include an anti-slip groove (40), the shape of the anti-slip groove is not limited, the anti-slip groove (40) may cause the surface of the winding shaft (4) to become uneven, so that the friction coefficient may be increased, and when the traction rope contacts the surface of the winding shaft (4), the anti-slip groove (40) may increase the friction force between the winding shaft (4) and the traction rope, so as to prevent the winding shaft (4) from slipping when the traction rope is wound.

With continued reference to fig. 5, the cord guiding mechanism (5) comprises two guide rods (51). The two guide rods (51) are fixed on the fixed base (1). Specifically, the rope guiding mechanism (5) may further include a fixing block (50), the two guide rods (51) are mounted on the fixing block (50), and the fixing block (50) is mounted on a top plate of the first base (11). The manner in which the two guide rods (51) are attached to the fixed block (50) is not limited, and the manner in which the fixed block (50) is attached to the first base (11) is not limited. Illustratively, welding, riveting, etc. may be included.

It is understood that in another embodiment, the cord guiding mechanism (5) may also be fixed to the bottom plate of the first base (1), in which case the "bottom plate" corresponds to the "top plate" in the previous embodiment. This corresponds to turning the hoist 180 degrees in the foregoing embodiment.

The rope guide mechanism (5) is arranged opposite to the reel (4), and the winch can be arranged at the bottom of the tower or at the top of the tower. The absolute position of the winch arranged at the tower bottom and the absolute position of the winch arranged at the tower top can be changed, but the relative position is not changed. If the winch is arranged at the bottom of the tower, as shown at A in figure 2, the rope guiding mechanism (5) is positioned above the winding shaft (4). If the hoist is arranged on the top of the tower, as shown at C in fig. 2, the rope guiding mechanism (5) is located below the reel (4). That is, when the hoist is disposed at the tower top, the hoist is turned 180 degrees compared to the hoist disposed at the tower bottom.

In the rope guide mechanism (5), the surface distance between two guide rods (51) is greater than or equal to the diameter of one traction rope and less than or equal to the diameter of two traction ropes, and the two guide rods (51) are used for guiding the traction ropes wound on the reel. The two guide rods (51) can be arranged in parallel or not, and the arrangement is not limited in the above. When the two guide rods (51) are parallel, the surface distance of the two guide rods (51) is equal to the distance between the central axes of the two guide rods minus the radius of the two guide rods (51). The surface distance between the two guide rods (51) is a definite value. The determined value is greater than or equal to the diameter of one traction rope and less than or equal to the diameters of two traction ropes.

When the two guide rods (51) are not parallel, if one guide rod of the two guide rods (51) is A and the other guide rod is B, (the length of the guide rod A is less than or equal to that of the guide rod B). Then, a perpendicular line can be drawn from any point on the central axis of the guide bar a to the central axis of the guide bar B, and the intersection point of the perpendicular line and the central axis of the guide bar B can be determined. This allows the distance from any point on the central axis of guide rod a to the central axis of guide rod B to be determined. When the guide bar a and the guide bar B of the two guide bars (51) are not parallel, the surface distance of the two guide bars (51) can be understood as a value obtained by subtracting the radius of the two guide bars (51) from the distance from a point on the central axis of the guide bar a to the central axis of the guide bar B. The surface distance of the two guide rods (51) is a value range. The minimum value in the value range is larger than or equal to the diameter of one traction rope, and the maximum value is smaller than or equal to the diameters of two traction ropes.

When the winch works, the rope guide mechanism (5) can guide the traction rope coiled on the reel (4), and the traction rope cannot be wound and knotted in high-speed movement, so that the hoisting efficiency can be improved.

When the surface distance between the two guide rods (51) is within the range of being larger than or equal to the diameter of one traction rope and smaller than or equal to the diameter of two traction ropes, the traction ropes can be guided. If the surface distance of the two guide rods (51) is smaller than the diameter of a traction rope, the traction rope cannot pass through the gap between the two guide rods (51). If the surface distance of the two guide rods (51) is greater than the distance between the two traction ropes, the traction ropes still can pass through the gap between the two guide rods (51) under the condition that the traction ropes are knotted, and thus the guiding effect of the two guide rods (51) is weakened.

Referring to fig. 7, the reel (4) is disposed obliquely relative to the guide rod (51), and a side of the reel (4) away from the guide rod is lower than a side of the reel close to the guide rod (51). When the reel receives the traction rope, the traction rope which is received firstly can slide into one side far away from the guide rods under the action of gravity, so that the condition that the received traction rope is accumulated in the reel (4) area corresponding to the gap between the two guide rods (51) can be avoided.

The two guide rods (51) may be the same or different in length. If the lengths of the two guide rods are the same, the traction rope is not easy to slide into a gap between the two guide rods when penetrating into the two guide rods. When the lengths of the two guide rods (51) are different, the traction rope can enter a gap between the two guide rods (51) conveniently, and therefore the working efficiency of the winch can be improved. Referring to fig. 8, one of the two guide rods (51) is 13 cm long, the other guide rod is 12 cm long, and the difference between the lengths of the two guide rods is 1 cm, so that the pull rope can conveniently penetrate. When the hauling rope slides in for the first time, the hauling rope can enter conveniently.

The guide bar may further include a guide bar body (510) and a guide bar head (511). At this time, the surface distance of the two guide rods specifically refers to the surface distance of the two guide rod bodies (510), that is, the surface distance of the two guide rod bodies (510) is greater than or equal to the diameter of one traction rope and less than or equal to the diameter of two traction ropes. The surface distance of the two guide rod heads (511) is larger than or equal to the diameter of a traction rope and smaller than the surface distance of the two guide rod bodies (510). Because the surface distance of the two guide rod heads (511) is smaller than that of the two guide rod bodies (510), after the traction rope slides into the two guide rods (51), the probability of the traction rope sliding out can be reduced to a certain extent by the two guide rod heads (511).

The material of the guide rod is not limited specifically, and for example, the guide rod can be made of a steel structure, a layer of stainless steel sleeve is added outside the guide rod, and the sleeve is polished to ensure that the outer edge is smooth, so that the friction force between the guide rod and the traction rope is as small as possible.

Further, the winch also comprises a falling prevention device (6). The fall-preventing device (6) is mounted on a hook a which is fixed on the first base (11) by a bar-shaped steel. The fall arrest device is detachable from the hook a. It should be noted that the hook a and the rope guide mechanism (5) are on the same side of the reel (4), and the rope guide mechanism (5) is located between the anti-falling device (6) and the reel (4). For example, the hook a and the rope guide mechanism (5) are fixed on the top plate of the first base (11), the hook a and the rope guide mechanism (5) are both arranged above the reel (4), and the anti-falling device (6) is arranged above the rope guide mechanism (5); the hook a and the rope guide mechanism (5) are fixed on the bottom plate of the first base (11), so that the hook a and the rope guide mechanism (5) are both arranged below the reel (4), and the anti-falling device (6) is arranged below the rope guide mechanism (5).

Referring to fig. 9 and 10, the anti-falling device (6) can refer to the structure of a chest riser, and includes a buckle ring (60), a body (61), a clamping piece (62), a pressing piece (63) and a spring (64), the buckle ring (60) can be provided with a plurality of parallel rings to be buckled with each other, the buckle ring (60) is detachably buckled on a hook a, the body (61) is buckled on the buckle ring (60), a pulling rope passes through the body (61), one end of the clamping piece (62) is rotatably connected with the body (61), the other end of the clamping piece (62) is provided with a barb, so that the pulling rope can be routed along the direction of the barb on the clamping piece (62).

Referring to fig. 11, if the pulling rope moves along the direction in which the barb is disposed (forward movement), the barb has no influence on the pulling rope, and the pulling rope can be smoothly routed. In fig. 11, the triangle represents a barb (which may also be called a pawl, ratchet, etc.). As shown in fig. 11 (a), when the traction rope moves in the direction in which the barb is disposed, the barb does not have an influence on the traction rope.

If the pulling rope moves against the direction in which the barb is arranged (reverse movement), the pulling rope is caught by the barb and cannot be routed. When the pulling rope moves against the direction in which the barbs are arranged, the pulling rope can be caught by the barbs and cannot be routed, as shown in fig. 11 (b). One end of the pressing piece (63) is rotatably connected with the clamping piece (62), the other end of the pressing piece (63) is abutted to the body (61), and the spring is connected with the pressing piece (63) and the clamping piece (62), so that the traction rope can be led to be routed in one direction.

It is noted that the fall arrest device (6) may be provided in both directions along the pull line. Specifically, if the winding machine is arranged at the bottom of the iron tower, when the rope is taken up, the anti-falling device (6) is located below the height of the hook a, see fig. 12. At this time, the falling-prevention device (6) allows the forward passing direction of the traction rope to be downward. When the rope is paid off, the fall-preventing device (6) is positioned above the height of the hook a, see fig. 13. At the moment, the anti-falling device (6) allows the positive passing direction of the traction rope to be upward. The length of the anti-falling device (6) is not more than that of the rod-shaped steel, so that the influence of the anti-falling device on the reel (4) in the rope receiving or releasing process can be avoided. For example, the height of the hook a with respect to the first base top plate may be 45 cm to 50 cm. The length of the anti-falling device (6) can be about 35 cm, so that a floating space of about 70 cm can be arranged above and below the anti-falling device, and the situation that the height cannot be retracted in the hoisting process can be avoided. For example, when the floating space is 70 cm, if the hoist is provided at the bottom of the tower and lifts the height of the weight more than a preset height when lifting the weight, the height of the weight can be lowered by 70 cm at most without causing the reverse movement of the traction rope in the hook member (62).

Referring to fig. 4 or fig. 6, the winch may further include a power source (7), the power source (7) may be electrically connected to the control unit (3), and the power source may be a dc power source or an ac power source, which is not limited herein. Because the winch can be operated in the field and is difficult to get electricity, the winch can be provided with a power supply (7) for supplying power.

Further, referring to fig. 4 or fig. 6, the hoisting machine may further include a foot switch (8), the foot switch (8) may be electrically connected to the control unit (3), and the foot switch (8) may control the driving motor (2) to start and stop through the control unit (2). Alternatively, the foot switch (8) may control the direction of rotation of the drive motor (2) and the like by the control unit (2). The foot switch (8) frees the hands of the user to allow more simultaneous operations.

It should be noted that, the winding machine may further include a control panel or a remote control switch, the control unit (3) may further include a wireless signal receiving module, and the operating state of the driving motor (2) may be remotely controlled through the control panel or the remote control switch, and the operating state of the driving motor (2) may include one or a combination of a rotating direction, a rotating speed, and a starting or stopping of the driving motor (2). Since the foot switch (8) is controlled by foot, it is difficult to perform a complicated operation. Certain strategies can be adopted to control the starting or stopping of the driving motor (2) and the rotating direction through the foot switch (8). The strategy for controlling the foot switch (8) is not limited herein, and two examples are provided below:

example one: when the operator steps on the foot switch (8) forward, the driving motor (2) rotates forward, when the operator steps on the foot switch (8) backward, the driving motor (2) rotates backward, and when the operator releases the foot, the rotation is stopped.

Example two: the preset rotation direction is a forward direction, the rotation direction is changed by continuously stepping twice, the stepping is started once, and the stepping is stopped once again.

The winch can be installed at the top of the tower or at the bottom of the tower, and can lift heavy objects or lower heavy objects, and the winch is not limited here. The material of the traction rope is not limited. For example, the hauling rope may be a nylon rope or a steel rope.
