Description

Hanging basket for tunnel

Technical Field

The invention relates to the technical field of tunnel construction equipment, in particular to a hanging basket for a tunnel.

Background

In recent years, tunnel construction projects have been increasing with importance placed on traffic construction. In the tunnel construction process, many personal safety accidents occur every year. Particularly, when tunnel construction is carried out on poor geology such as weak surrounding rocks and easily weathered phyllite, due to the fact that geological deformation is large and the weathering resistance is poor, rock debris is generated due to fragile falling of geology. Loose soil layers and broken stones can even fall in a large area in the blasting area of the tunnel, and great safety risks are caused to constructors in the tunnel.

Baskets are often used during tunnel construction. However, most of the existing hanging baskets are open type hanging baskets, and a protective ceiling for protecting the top of constructors is not arranged; if loose soil layers and broken stones drop in the tunnel construction process, the hanging basket without the protective ceiling can cause great threat to the personal safety of constructors. Although few hanging baskets have protective ceilings, the protective ceilings are fixed protective ceilings or turnover protective ceilings; the protective ceiling of the hanging basket occupies a large space, is clumsy to use, cannot be flexibly adjusted according to the complex landform in the tunnel, and limits the use of the hanging basket to a certain extent.

Example one

Referring to fig. 1 to 9, a basket for a tunnel includes a main platform assembly 100, a lifting driving member 200, a support assembly 300, and a protective ceiling 400.

The main platform assembly 100 includes a main platform 110 for providing a standing surface for a constructor, a fence 120 around the periphery of the main platform 110, and a sub-platform 600 hinged to the main platform 110. In which the rail 120 is erected on a partial area of the periphery of the main platform 110, i.e., the rail 120 does not completely surround the entire main platform 110, but two oppositely disposed openings are formed between the rail 120 and the main platform 110. The sub-platform 600 is disposed at the opening. When the sub-platform 600 is not deployed, the sub-platform 600 stands on the main platform 110 in a vertical state and is perpendicular to the main platform 110. The vertically arranged secondary platform 600 cooperates with the fence 120 to surround the primary platform 110, forming a fence that prevents the constructors on the primary platform 110 from falling over the primary platform 110.

Referring to fig. 5, the lifting driving member 200 is fixedly mounted on the main platform assembly 100. Specifically, two fixing arms 130 are fixedly mounted on the outer side of the rail 120 of the main platform assembly 100. The fixed arm 130 is a hollow straight tube that is vertically placed and has a square opening. The lifting driving members 200 are lifting hydraulic cylinders, and in order to increase the stability of the lifting driving members 200 during lifting, the number of the lifting driving members 200 is preferably two or more. The main body part of the lifting hydraulic cylinder is arranged inside the fixing arm 130, namely the main body part of the lifting hydraulic cylinder cannot be seen from the outside, so that the attractiveness of the hanging basket is improved. When the lifting hydraulic oil cylinder is started, a piston rod of the lifting hydraulic oil cylinder extends and retracts in the vertical direction.

In some possible embodiments, the lifting driving member 200 may also be an electric push rod or an electric cylinder, while ensuring that the lifting driving member 200 can be lifted stably.

The supporting component 300 is fixedly installed on the moving portion of the lifting driving component 200, and the lifting driving component 200 can drive the supporting component 300 to lift according to a preset lifting height, or artificially control the lifting height of the lifting driving component 200 according to an acting space in a tunnel. Specifically, the support assembly 300 includes vertically arranged lifting arms 310, and the number of the lifting arms 310 is preferably two or more to ensure the stability during lifting. The lower section of the lifting arm 310 is positioned in the hollow straight pipe and is fixedly connected with a piston rod of a lifting hydraulic oil cylinder, and the upper section of the lifting arm 310 extends upwards out of the hollow straight pipe.

As shown in fig. 7, a nylon slider 320 is filled between the lifting arm 310 and the inner side wall of the fixing arm 130, and the nylon slider 320 is fixed on the inner side wall of the hollow straight tube. When the lifting hydraulic oil cylinder stretches and retracts to drive the lifting arm 310 to lift, the nylon slider 320 limits the periphery of the lifting arm 310. In addition, the nylon slider 320 has a low friction coefficient on its surface, so that it does not generate a large friction resistance to the movement of the lifting arm 310.

The protective roof 400 is movably mounted on the supporting member 300 and can be turned over relative to the supporting member 300, so that the protective roof 400 is directly above the platform surface of the main platform assembly 100 or laterally above the platform surface of the main platform assembly 100. The protective roof 400 is generally plate-shaped and has substantially the same size as the main platform 110.

In some embodiments, the deployment process of the protective canopy 400 is as follows: the protective roof 400 is turned toward the main platform 110 with respect to the supporting member 300, and the turning angle is not particularly limited, and it is preferable that the protective roof 400 is positioned right above the platform surface of the main platform 110 in a horizontal state or a nearly horizontal state. The moving part of the lifting driving member 200 is lifted upwards to drive the lifting arm 310 to be lifted, and the lifting arm 310 is lifted to drive the protective ceiling 400 arranged on the supporting assembly 300 to be lifted. The lifting height of the lifting driving member 200 is adjusted according to the size of a specific accommodating space in the construction tunnel. When there is a large space above the gondola, the lifting height of the lifting driving member 200 can be increased appropriately to allow a sufficient working space for the worker below. When the empty space above the basket is insufficient, the lifting height of the lifting driving member 200 is appropriately reduced to avoid the protective ceiling 400 from being damaged. In summary, the unfolding process of the protective ceiling 400 can be adjusted according to the size of the specific accommodating space in the construction tunnel, and the flexibility is strong.

In some embodiments, the process of stowing the protective canopy 400 is as follows: the protective roof 400 is turned away from the main platform 110 relative to the supporting assembly 300, and the turning angle is not limited in particular, and it is preferable that the protective roof 400 is in an upright state or a nearly upright state above the side of the platform surface of the main platform 110. The moving part of the lifting driving member 200 is retracted downward to drive the lifting arm 310 to retract into the fixing arm 130, and the lifting arm 310 descends to drive the protective ceiling 400 to fall down. Until the protective roof 400 is received on the outer side of the main platform assembly 100. In summary, the protective ceiling 400 can be stored when not in use, so as to reduce the occupied space, and the hanging basket is suitable for compact construction space.

As shown in fig. 3 and 4, in some embodiments, the protective canopy 400 is horizontally oriented when it is flipped over the top of the platform surface of the main platform assembly 100 and vertically oriented when it is flipped over the side of the platform surface of the main platform assembly 100. When the protective roof 400 is positioned in a horizontal position directly above the deck of the main platform assembly 100, it provides the greatest protective area for the workers below. When the protection ceiling 400 is stored in the upright state, the protection ceiling 400 can be attached to the outer side surface of the main deck 110 as much as possible, thereby reducing the occupied space when the protection ceiling 400 is stored.

Referring to fig. 6, in some embodiments, the hanging basket further includes a ceiling limiting rod 500, one end of the ceiling limiting rod 500 is movably connected to the supporting component 300, and the other end of the ceiling limiting rod 500 is used for being clamped with the protective ceiling 400 when the protective ceiling 400 is turned over to be directly above the platform surface of the main platform component 100, so as to increase a stressed supporting point of the protective ceiling 400. Specifically, one end of the ceiling limiting rod 500 is hinged in the lifting arm 310, and the other end is detachably connected with the protective ceiling 400. When the protective ceiling 400 is turned over the platform surface of the main platform assembly 100, one end of the ceiling limiting rod 500 is embedded into the limiting groove of the protective ceiling 400 to limit the protective ceiling 400, and meanwhile, the stress supporting points of the protective ceiling 400 are increased, and the protective ceiling 400 is prevented from being turned over continuously. When the protective ceiling 400 needs to be stored, one end of the ceiling limiting rod 500 is pulled out of the protective ceiling 400.

Referring to fig. 2, in some embodiments, the basket further comprises a secondary platform restraining assembly 700. One side of the sub platform 600 is hinged to the outer side of the main platform assembly 100. The secondary platform limiting component 700 is connected with the secondary platform 600 and the primary platform component 100, and is used for limiting the secondary platform 600 from excessively turning downwards after the secondary platform 600 is flattened relative to the primary platform component 100. Specifically, the secondary platform limiting assembly 700 is a linkage mechanism including a first link 710 and a second link 720 hinged to each other. The first link 710 is hinged to the main platform assembly 100, and the second link 720 is hinged to the sub platform 600.

In the construction process, in order to increase the standing area of the basket, the constructor can flatten the link mechanism to make the swing angle between the first link 710 and the second link 720 be 180 degrees, and put down the sub platform 600 horizontally. When the hanging basket needs to be collected, the link mechanism is folded, so that the first link 710 and the second link 720 are overlapped, the auxiliary platform 600 is erected on the main platform 110, the occupied space of the auxiliary platform 600 is reduced, and an enclosure is formed.

A guard rail 610 is also hinged on the sub platform 600 to protect the constructors working on the sub platform 600 when the sub platform 600 is horizontally laid down.

In some embodiments, the sub-platform 600 is made of a thin steel plate with holes or a steel wire mesh to reduce the weight of the nacelle, while ensuring that the sub-platform 600 has sufficient mechanical strength to withstand the constructors.

Referring to fig. 4 and 9, in some embodiments, two parallel sliding grooves 410 are disposed on the supporting beams of the protective ceiling 400. The chute 410 may be a through slot. The ceiling limiting shaft pins 340 at both ends of the supporting assembly 300 are respectively inserted into the two sliding grooves 410 and form two pairs of moving pairs which can slide along the sliding grooves 410 and rotate, and the protective ceiling 400 can turn around the supporting assembly 300 through the pairs of moving pairs. The sunroof 400 is slidably coupled to the support assembly 300 in a vertical direction along the slide grooves 410 to raise or lower the sunroof 400.

During deployment of the protective roof 400, the constructor manually lifts the protective roof 400 up along the chute 410 until the bottom surface of the protective roof 400 is higher than the top surface of the main platform assembly 100. Then, the protective roof 400 is turned over around the roof limit shaft pins 340 toward the main platform assembly 100, so that the protective roof 400 is positioned right above the platform surface of the main platform assembly 100 in a horizontal state.

In the process of storing the protection ceiling 400, the constructor manually turns the protection ceiling 400 in a direction away from the main platform assembly 100, so that the protection ceiling 400 is vertically above the platform surface of the main platform assembly 100. Then, the protection ceiling 400 slides down to the position of the ceiling stopper pin 340 along the slide groove 410, so that the protection ceiling 400 is accommodated on the outer side surface of the main platform assembly 100.

Referring to fig. 8 and 9, in some embodiments, the supporting assembly 300 includes a supporting beam 330 and a ceiling-restraining shaft pin 340 screwed to two ends of the supporting beam 330, and a side of the ceiling-restraining shaft pin 340 away from the supporting beam 330 is inserted into the sliding slot 410 to form the kinematic pair. Specifically, two lifting arms 310 are symmetrically disposed about the supporting beam 330, and two ends of the supporting beam 330 are respectively inserted into and fixedly connected to the tops of the two lifting arms 310 in a transverse direction. On the side of the sliding groove 410 away from the support beam 330, a circlip 350 is disposed between the head of the ceiling limiting shaft pin 340 and the side walls on both sides of the sliding groove 410, and the circlip 350 is pressed against the protective ceiling 400 by the head of the ceiling limiting shaft pin 340 to limit the lateral movement of the protective ceiling 400.

Referring to fig. 9, in some embodiments, the protective canopy 400 is provided with a hook 420 movably connected thereto, and the hook 420 is configured to hook to the main platform assembly 100 when the protective canopy 400 is received at one side of the main platform assembly 100. Specifically, the hook member 420 is hinged to the canopy frame 430 of the protective canopy 400.

Referring to fig. 9, in some embodiments, the protective canopy 400 includes a canopy frame 430 and a canopy cover 440 disposed in the canopy frame 430. In some embodiments, the ceiling cover 440 is preferably a see-through cover with a high degree of transparency so as not to obstruct the operator's view of the conditions above it.

Referring to fig. 1-6, in some embodiments, the basket further includes a collision prevention structure and a controller 800, where the collision prevention structure is electrically connected to the controller 800 and is capable of sending a signal to the controller 800 when the collision prevention structure is pressed by an external force; the controller 800 may analyze the signal to obtain an analysis result, and control a power source of the basket or issue an alarm according to the analysis result. The power source for the gondola in some embodiments includes a lifting drive 200 that drives the lifting of the protective roof 400.

Specifically, the anti-collision structure is composed of the safety edge collision strip 900 with different specifications and models and corresponding electrical components, and the electrical components used in cooperation with the safety edge collision strip 900 (hereinafter referred to as an anti-collision strip) are prior art and will not be described herein again.

In some embodiments, the bumper strip includes an inner disposed induction band and a flexible contact edge surrounding the induction band. The induction belt is provided with a safety contact. The flexible contact edge is made of rubber material, so that the flexible contact edge has certain elasticity, the anti-collision strip can be protected from being damaged, the impact angle of the anti-collision strip is allowed to exceed 90 degrees, and specifically, the rubber material can be ethylene propylene diene monomer. The anti-collision strip is fixedly arranged at each position of the hanging basket through an aluminum alloy base arranged at the bottom of the anti-collision strip.

Referring to fig. 10, when the basket is collided to cause the flexible contact edges of the bumper strips to be pressed, the conductors of the sensor strip are contacted with each other, so that the current in the conductors is changed, and the current change signal is transmitted to the controller 800 for analysis. When the controller 800 analyzes the signal to obtain the result that the basket is actually collided by the foreign object, the controller 800 turns off the power source for driving the basket to move or gives an alarm.

In some embodiments, the activation distance of the bumper strip is between 3mm and 6mm, i.e., the bumper strip sends a signal to the controller 800 after the flexible contact edge generates a deformation amount of 3mm to 6 mm.

In some embodiments, the trigger force value of the bumper strip is between 4N and 10N, that is, the bumper strip sends a signal to the controller 800 after the flexible contact edge receives the acting force of 4N to 10N.

Referring again to FIG. 1, bumper strips are provided on each edge of the main platform assembly 100.

After the constructor enters the interior of the hanging basket, the hanging basket is driven to be lifted by the suspension arm, so that the constructor reaches the position to be operated. When the basket is bumped, the controller 800 sends a command to turn off the power source, and the boom stops moving to avoid the basket from being damaged by the continued movement.

In summary, the anti-collision strip and the controller 800 form a stop protection system for protecting the hanging basket from being damaged, and after the controller 800 closes the power source for driving the hanging basket to move, the operator needs to manually release the stop command of the controller 800 to continue moving the hanging basket.

In addition, in order to avoid the hanging basket from being mistakenly touched by an operator after the hanging basket is collected, the protection system can be set to be in a closed mode. The constructor enters a command at the controller 800 to shut down the protection system. The controller 800 then masks signals from all or particular crash structures (e.g., crash strips on the main basket assembly or crash strips on the protective ceiling 400) to eliminate false feedback from operator mis-hits.

As shown in fig. 3, in some embodiments, the crash ceiling 400 has the crash structure mounted thereon; when the protection ceiling 400 is collided during the movement operation, so that the anti-collision structure on the protection ceiling 400 is squeezed, the anti-collision structure can send a signal to the controller 800. Specifically, the anti-collision structure is an anti-collision strip, and the anti-collision strip is arranged at each edge of the protective ceiling 400 which is likely to be touched.

When the protective ceiling 400 is collided in the process of being unfolded or stored and the bumper strips are extruded, the bumper strips send signals to the controller 800, and the controller 800 analyzes the signals and controls the lifting driving pieces to stop operating after confirming that the protective ceiling 400 is actually collided by foreign objects, so as to avoid the protective ceiling 400 from being damaged due to continuous movement.

When the gondola is used in a complicated enclosed environment such as a tunnel, it is necessary to open the protective ceiling 400 to protect the top of a constructor. However, when the space above the protective roof 400 is insufficient, there is an optimum value for the specific elevation of the protective roof 400. The worker under the protection ceiling 400 has enough space to facilitate the construction operation, and the protection ceiling 400 is prevented from being damaged by the rock wall above the protection ceiling 400 due to over-high rise. The optimal raised position of the protective roof 400 is therefore to stop just touching the rock wall above. Since the empty space above the protection ceiling 400 is not a constant value, the elevation height of the protection ceiling 400 cannot be set in advance, but the optimum elevation height of the protection ceiling 400 is determined according to the working environment of the gondola at the site. If the elevation of the elevation drive 200 is manually controlled by the operator (the elevation drive 200 is a hydraulic ram in some embodiments), it may malfunction due to poor field environment visibility conditions or carelessness of the operator himself, and also increase the workload of the operator.

After the controller 800 is set up and the lifting actuators 200 capable of controlling the lifting height and the touch-sensitive bumper strips are controlled, an automated process can be used to determine the optimal lifting height of the protective roof 400. Under the control of the controller 800, the lifting driving member 200 drives the protection ceiling 400 to be lifted until the bumper strips on the protection ceiling 400 collide with the objects above. At this time, the bumper strip sends a signal to the controller 800, and after the controller 800 analyzes the signal and confirms that the bumper strip is indeed collided, the controller 800 controls the lifting driving member 200 to stop lifting, so as to prevent the protective ceiling 400 from being damaged due to continuous lifting. At this time, the protection ceiling 400 reaches an optimal lifting height, which is the maximum height that the protection ceiling 400 can be lifted on the premise of avoiding the protection ceiling 400 from being damaged, so as to ensure that the constructors below have a certain activity space. In summary, after the bumper strips are disposed on the protective roof 400, the bumper strips, the controller 800 and the lifting driving member 200 cooperate to automatically control the lifting and stopping of the protective roof 400, so that the protective roof 400 reaches an optimal lifting height, and the workload of the constructor caused by controlling the lifting height of the lifting driving member 200 is eliminated.

In some embodiments, the protection ceiling 400 is lifted to a proper height according to a preset height, but when the hanging basket is at a construction site, the height of the protection ceiling 400 needs to be adjusted due to the change of construction positions, and the lifting height of the lifting driving member 200 can be manually adjusted by a constructor so as to ensure that the protection ceiling 400 is at an optimal construction protection height.

Referring to fig. 2, in some embodiments, the nacelle further includes a sub-platform 600 hinged to the main platform assembly 100, and the collision prevention structure is mounted on the sub-platform 600. When the sub-platform 600 is impacted during the flattening or retracting process, so that the anti-collision structure on the sub-platform 600 is pressed, the anti-collision structure can send a signal to the controller 800. Specifically, the edge of the sub-platform 600 is provided with an anti-collision strip forming an anti-collision structure. After the bumper strip is extruded, the bumper strip sends a signal to the controller 800, and the controller 800 sends an alarm after confirming the collision result to remind the constructor to remove the object colliding with the sub-platform 600.

In some embodiments, to avoid the controller 800 from generating an alarm due to a mistake by the constructor after the sub-platform 600 is retrieved, the anti-collision structure on the sub-platform 600 is set to a mode that can turn off the protection system. After the controller 800 shields the signal sent by the bumper strip on the sub-platform 600, even if the constructor mistakenly touches the bumper strip on the sub-platform 600, the controller 800 does not send an alarm.

Compare prior art, the beneficial effect of this application: the protective ceiling 400 is movably arranged on a hanging basket, and the unfolding process of the protective ceiling comprises the following steps: the protective roof 400 is turned over relative to the support assembly 300 in the direction of the main platform assembly 100, so that the protective roof 400 is positioned right above the platform surface of the main platform assembly 100; the lifting driving member drives the supporting assembly 300 to lift according to a preset lifting height, and further drives the protective ceiling 400 to lift. The top of the constructor can be protected by unfolding the protection ceiling 400, and the lifting height of the protection ceiling 400 is controllable, and can be flexibly adjusted according to the landform of the construction tunnel. In addition, the protective ceiling 400 of the basket can also be received. The storage process comprises the following steps: the protective canopy 400 is flipped over relative to the support assembly 300 in a direction away from the primary platform assembly 100 such that the protective canopy 400 is laterally above the platform face of the primary platform assembly 100; the lifting driving member drives the supporting assembly 300 to descend, and further drives the protective ceiling 400 to descend so as to be accommodated on the outer side surface of the main platform assembly 100. Therefore, the protective ceiling 400 can be stored when not in use, and the occupied space is reduced, so that the hanging basket is suitable for compact construction space.
