Technical Field

[0001] The present invention relates to the field of utility tunnel construction, and specifically to a hoisting device for in-tunnel construction for assembling integral prefabricated components of a utility tunnel. Background Art

[0002] A utility tunnel is the main place for centralized laying of large-scale device pipelines. It consists of columns, crossbeams, and trusses made of steel structures or reinforced concrete structures. It can be divided into single-layer or multi-layer, passable or non-passable, etc. Some utility tunnels are built by in-situ casting, or can also be built by assembling prefabricated components to improve the construction efficiency.

[0003] When assembling prefabricated components in a tunnel, a crane is often required to hoist the prefabricated components to a preset position. However, the space in the tunnel is relatively narrow, resulting in the inability of existing cranes to carry out effective hoisting work in the tunnel. Due to the limited space in the tunnel, existing cranes cannot move flexibly in the tunnel, that is, they cannot quickly and effectively lift the prefabricated components and transport them to the assembly position. Therefore, a hoisting device for in-tunnel construction is specifically designed to solve this problem. Summary of the Invention

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In the present invention, when the multi-directional walking assembly is moving, the drive motor drives the Mecanum wheels through the belt transmission member to move. The arrangement of the four Mecanum wheels has its own unique characteristics. The omnidirectional motion equipment based on Mecanum wheel technology can realize forward movement, lateral movement, oblique movement, rotation and their combination. It can rotate 180 degrees without taking up much space and can also move sideways perfectly. It is particularly suitable for environments with limited transfer space and narrow working channels, increases the utilization rate of the space in the tunnel, facilitates the lifting and assembly of prefabricated parts, and improves the work efficiency of the prefabricated parts assembly in the pipeline corridor.

[0024] 2. In the present invention, after the second driving motor is started, it can drive the rotating base shaft to rotate through the gear transmission member. The rotation of the rotating base shaft will drive the top plate to rotate, thereby realizing 360-degree rotation adjustment of the vacuum suction cup assembly without dead angles, which is beneficial to improving the flexibility of the device. Moreover, when the top plate rotates, the ball end of the universal ball contacts the bottom of the top plate, playing a rolling support role for the top plate and evenly distributing the force on the top plate to ensure the stability of the top plate during rotation.

[0025] 3. In the present invention, the telescopic warehouse frame slides inside the basic warehouse frame, and a hydraulic rod 1 is installed inside the telescopic warehouse frame. The movable end of the hydraulic rod 1 contacts the inner wall of the basic warehouse frame through the connecting plate. When the hydraulic rod 1 is extended, the connecting plate is connected to the basic warehouse frame, which drives the telescopic warehouse frame as a whole to extend to the outside of the basic warehouse frame, that is, the telescopic frame assembly is extended. Conversely, the hydraulic rod 1 is shortened to shorten the telescopic frame assembly, so as to increase the height position that the device can be lifted to. The dovetail slide and the dovetail slider slide to support and limit the telescopic warehouse frame, ensuring that the telescopic warehouse frame slides smoothly inside the basic warehouse frame. At the same time, the fixed stop bar and the movable stop bar touch and interfere with each other, avoiding accidents when the telescopic warehouse frame is completely pulled out from the inside of the basic warehouse frame, thereby further improving the stability of the device.

[0026] 4. In the present invention, the hydraulic rod 2 is rotatably connected to the positive U-shaped seat through the hydraulic rod seat, and is rotatably connected to the inverted U-shaped seat through the rotating block. In addition, the hydraulic rod 2 is rotatably connected to the hinged seat through the rotating seat, that is, when the hydraulic rod 2 is extended, the basic warehouse frame can be pushed upward, and when the hydraulic rod 2 is shortened, the basic warehouse frame can be pulled downward. The rotation of the basic warehouse frame is controlled by the extension and retraction of the hydraulic rod 2, that is, the rotation of the telescopic frame assembly is realized to achieve the regulation of its inclination angle.

[0027] 5. In the present invention, when hoisting a prefabricated component, the fixed suction cup is brought into contact with the surface of the prefabricated component. At this time, the vacuum pump is turned on for air extraction, and the negative pressure is transmitted to the fixed suction cup through the air pipe, the long horizontal pipe, and then the fixed suction cup and the surface of the prefabricated component are vacuum adsorbed to complete fixation. At the same time, the negative pressure is also transmitted to the movable suction cups on both sides through the adsorption substrate, the double-headed threaded hose, the air pipe, and the short horizontal pipe, and the movable suction cups also complete fixation by vacuum adsorption with the surface of the prefabricated component. Conversely, by canceling the negative pressure suction force, the prefabricated component can be removed. Moreover, movable plates are installed on both sides, and the movable plates can slide between the two annular frames through the support sliders. When sliding, the double-headed threaded hose is stretched, and thus the distance between the movable plate and the adsorption substrate can be adjusted. That is, when adsorbing prefabricated components of different sizes, the movable plates on both sides can be adjusted by corresponding distances, so that the adsorption points are more comprehensively dispersed on the surface of the prefabricated component, thereby improving the stability of vacuum adsorption.

[0028] 6. In the present invention, when hoisting, according to the state of the upper space in the tunnel, the corresponding support method is selected. If the upper space of the device is an arc surface, the second electric telescopic rod is in a contracted state, and the support is carried out by the cooperation of the support seat and the arc-shaped rubber sheet, making it more fitting for arc surface support. If the upper space is a plane, the second electric telescopic rod extends to drive the plane support plate to move upward, so that the bottom surface position of the plane support plate is higher than the arc-shaped upper surface position of the support seat. At this time, the plane is supported by the cooperation of the plane-shaped rubber sheet and the plane support plate. The dual top contact methods can be selected corresponding to the actual use conditions.

[0029] 7. In the present invention, the first electric telescopic rod extends to make the support seat move upward, and finally contacts and supports the contact point in the upper space, playing a supporting role for the upper space. And when supporting, the reverse acting force of the support can be fed back to the ground by the multi-directional walking component, which is equivalent to squeezing the device inside the tunnel, playing a role in supporting and limiting the device, so that the hoisting device is more stable during hoisting and is not prone to unexpected safety accidents such as tilting.

[0061] The working principle of the present invention is as follows:

[0062] The principle of the chassis drive rotation assembly 2 driving the top plate 3 to rotate is as follows:

[0063] After the driving motor two 16 is started, the rotating base shaft 18 can be driven to rotate through the gear transmission member 17. The rotation of the rotating base shaft 18 will drive the top plate 3 to rotate, realizing 360-degree dead-angle-free rotation adjustment of the vacuum chuck assembly 7, which is beneficial to improving the flexibility of the device;

[0065] The telescoping bin frame 22 slides inside the base bin frame 21, and a hydraulic rod one 26 is installed inside the telescoping bin frame 22. The movable end of the hydraulic rod one 26 contacts the inner wall of the base bin frame 21 through the connecting plate 27. When the hydraulic rod one 26 extends, since the connecting plate 27 is connected to the base bin frame 21, the whole telescoping bin frame 22 is driven to extend out of the base bin frame 21, that is, the telescoping of the telescoping frame assembly 5 is realized. On the contrary, when the hydraulic rod one 26 shortens, the telescoping of the telescoping frame assembly 5 is realized to increase the height position that the device can lift;

[0066] The principle of the rotation drive assembly 4 driving the telescoping frame assembly 5 to rotate is as follows:

[0067] The hydraulic rod two 31 is rotatably connected between the hydraulic rod seat 30 and the positive U-shaped seat 29, and the hydraulic rod two 31 is rotatably connected to the inverted U-shaped seat 33 through the rotating block 32. Moreover, the hydraulic rod two 31 is rotatably connected to the hinge seat 19 through the rotating seat 20. That is, when the hydraulic rod two 31 extends, the base bin frame 21 can be pushed up, and when the hydraulic rod two 31 shortens, the base bin frame 21 can be pulled down. The rotation of the base bin frame 21 is controlled by the telescoping of the hydraulic rod two 31, that is, the telescoping frame assembly 5 is rotated to realize the adjustment of its inclination angle;

[0068] The hoisting principle of the hoisting assembly 6 is as follows:

[0069] The forward and reverse rotation of the driving motor three 34 drives the winding disc 35 to rotate forward and backward. When the winding disc 35 rotates forward, the steel wire rope 37 is wound, and when the winding disc 35 rotates backward, the steel wire rope 37 is released from the inside of the winding disc 35. When the steel wire rope 37 is wound, the steel wire rope 37 drives the vacuum chuck assembly 7 to move upward. When the steel wire rope 37 is unwound, it drives the vacuum chuck assembly 7 to move downward;

[0070] The principle of the vacuum chuck assembly 7 adsorbing the precast member is as follows:

[0071] When hoisting the prefabricated component, the fixed suction cup 50 is brought into contact with the surface of the prefabricated component. At this time, the vacuum pump 40 is turned on for air extraction. The negative pressure is transmitted to the fixed suction cup 50 through the ventilation pipeline 39 and the long horizontal pipe 41, and then vacuum adsorption is carried out between the fixed suction cup 50 and the surface of the prefabricated component to complete fixation. At the same time, the negative pressure is also transmitted to the movable suction cups 52 on both sides through the adsorption substrate 49, the double-headed threaded hose 42, the ventilation pipeline 39 and the short horizontal pipe 51. The movable suction cups 52 also carry out vacuum adsorption with the surface of the prefabricated component to complete fixation. On the contrary, by canceling the negative pressure suction force, the prefabricated component can be removed. Moreover, movable plates 43 are installed on both sides, and the movable plates 43 can slide between the two annular frames 44 through the support sliders 47. That is, when adsorbing prefabricated components of different sizes, the movable plates 43 on both sides can be adjusted by corresponding distances to make the adsorption points more comprehensively dispersed on the surface of the prefabricated component;

[0072] The support principle is as follows:

[0073] When hoisting, according to the state of the upper space in the tunnel, the corresponding support method is selected. If the upper space of the device is an arc surface, the second electric telescopic rod 60 is in a contracted state, and the support is carried out by the cooperation of the support seat 56 and the arc rubber sheet 57 to make it more fitting for arc surface support. If the upper space is a plane, the second electric telescopic rod 60 extends to drive the plane support plate 59 to move upward, so that the bottom surface position of the plane support plate 59 is higher than the arc upper surface position of the support seat 56. At this time, the plane type rubber sheet 58 and the plane support plate 59 are used in cooperation to support the plane. The dual top contact method can be selected according to the actual use conditions;

[0074] After the selection is completed, the first electric telescopic rod 55 extends to make the support seat 56 move upward, and finally contacts and supports the contact point of the upper space, playing a supporting role for the upper space. And when supporting, the reverse acting force of the support can be fed back to the ground by the multi-directional walking component 1, which is equivalent to squeezing the device inside the tunnel, playing a role of supporting and limiting the device, making the hoisting device more stable during hoisting and not prone to accidental safety accidents such as tilting.

[0075] When the multi-directional walking component 1 is walking, the driving motor one 12 drives the Mecanum wheel 10 to move through the belt transmission part 11. The setting of the four Mecanum wheels 10 endows the four Mecanum wheels 10 with their unique characteristics. Based on the Mecanum wheel technology, the omnidirectional motion equipment can realize motion modes such as forward movement, lateral movement, diagonal movement, rotation and their combinations. It can rotate 180 degrees without occupying much space and can also move perfectly laterally, which is especially suitable for environments with limited transfer space and narrow operation channels;

[0076] After reaching the predetermined point, adjust the angle of the telescopic frame assembly 5 through the rotation drive assembly 4, and adjust the length of the telescopic frame assembly 5 itself to adapt to the lifting point. Rotate the top plate 3 by the chassis drive rotation assembly 2 so that the vacuum suction cup assembly 7 is directly above the prefabricated component. Then, support it with the top support assembly 53 to play a role in squeezing and limiting the device, strengthening the stability of the lifting device. Finally, control the lifting of the vacuum suction cup assembly 7 by the lifting assembly 6, and make the vacuum suction cup assembly 7 vacuum-adsorb and fix the prefabricated component to complete the lifting.

[0077] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
