Description

Technical Field

[0001] The present invention belongs to the technical field of pipe hoisting equipment in pipe galleries, and specifically refers to a large pipe hoisting equipment for pipe galleries. Background Art

[0002] A pipe gallery usually refers to a structure specifically designed to accommodate and manage pipelines, cables, communication lines, etc. It is usually an underground or elevated structure used to concentrate and protect various pipelines and cables for easy maintenance and management. When carrying out hoisting operations in a pipe gallery, it is necessary to fully understand and plan the environment in the pipe gallery before starting the hoisting to ensure that the pipeline can pass through the required path safely and unobstructed. At the same time, the pipeline should be properly reinforced and protected to avoid breakage or damage during the hoisting process.

[0003] Currently, when carrying out pipe hoisting operations in a pipe gallery, only two sets of lifting ropes are used to fix the pipeline. The operation is simple and the cost is relatively low. However, the fixing effect is directly related to the smoothness of the pipeline surface. When the pipeline surface is smooth, it is easy for the lifting ropes to fall off from the pipeline, causing the pipeline to fall and injure the construction workers at the bottom. Therefore, how to effectively fix the pipeline and not affect the docking task between multiple pipelines is the problem to be solved in this application. Summary of the Invention

[0004] In view of the above situation, in order to improve the fixing effect of pipelines in a pipe gallery and at the same time achieve the design goal of facilitating connection during pipeline installation, the present invention provides a large pipe hoisting equipment for pipe galleries, which adapts to the fixation of pipelines with different diameters through an automatic clamping method. The single-sided clamping and fixing method not only ensures the stability of the pipeline but also does not increase the difficulty of pipeline docking. The operation is simple and fast, saving labor costs.

[0005] The technical solution adopted by the present invention is as follows: A large pipe hoisting equipment for pipe galleries provided by the present invention includes a pipe gallery, a hanging support, and a pipe gallery pipeline. The hanging support is fixedly installed on the inner wall of the pipe gallery, and the pipe gallery pipeline is installed on the hanging support. A pipe gallery transport vehicle for transporting pipelines is arranged on the bottom wall in the pipe gallery, and a pipeline fixing and docking device for fixing the pipeline and adjusting its position is arranged on the top wall of the pipe gallery. The pipeline fixing and docking device includes a pipeline transmission and transport device, a single-sided automatic limit fixing device, and a clamping and fixing structure. The pipeline transmission and transport device is fixedly installed on the top wall of the pipe gallery. The single-sided automatic limit fixing device is in contact connection with one end of the pipe gallery pipeline and is fixedly connected to the pipeline transmission and transport device. The clamping and fixing structure is in snap connection with the pipe gallery pipeline and is fixedly connected to the pipeline transmission and transport device.

[0006] Furthermore, the pipeline transmission and transportation device includes a track, a rack, and an edge card slot. The track is fixedly installed on the top wall of the pipe gallery. The edge card slot is fixedly arranged on the side wall of the track. The rack is fixedly arranged on the top wall of the track. There are a first gear and a second gear meshing and rotatably connected on the rack. A first connecting plate is provided at the bottom of the first gear, and the first gear is snap-fitted and rotatably arranged on the first connecting plate. A first connecting disk is fixedly connected to the bottom of the first connecting plate, and a first chain is connected inside the first connecting disk. Similarly, a second connecting plate is provided at the bottom of the second gear, and the second gear is snap-fitted and rotatably arranged on the second connecting plate. A second connecting disk is fixedly connected to the bottom of the second connecting plate, and a second chain is connected inside the second connecting disk.

[0007] Furthermore, sliding blocks are respectively arranged on the outer walls of the first connecting plate and the second connecting plate, and the sliding blocks are snap-fitted and slid in the edge card slot on the track. The first gear and the second gear are respectively connected to a motor, and the first gear and the second gear are driven to rotate by the motor.

[0008] Furthermore, the unilateral automatic limit and fixing device includes an automatic clamping device and an automatic locking structure. The automatic clamping device is connected to the pipe gallery pipeline in a contact manner, and the automatic locking structure is fixedly arranged on the automatic clamping device. The automatic clamping device includes a central cylinder, an edge touch plate, a touch plate chute, an elastic pressing protrusion, a base disk, a bending bracket, a touch piece, and an arc-shaped resistance increasing piece. The base disk is fixedly connected to the first chain. The central cylinder is fixedly arranged at the center of the base disk. The touch plate chutes are arranged in an array on the side wall of the central cylinder. The edge touch plate is snap-fitted and slid along the touch plate chute. The elastic pressing protrusion is fixedly arranged on the bottom wall of the edge touch plate. A card slot penetrating the upper and lower walls of the base disk is provided on the base disk. The bending bracket is snap-fitted and rotatably arranged in the card slot of the base disk, and the bending bracket and the base disk are connected by a torsion spring. The touch piece is hinged to one end of the bending bracket. The arc-shaped resistance increasing pieces are linearly arranged on the other side of the bending bracket.

[0009] Preferably, the edge touch plate and the touch plate chute are fixedly connected by a spring.

[0010] Furthermore, the elastic pressing protrusion is in contact connection with the touch piece, the arc-shaped resistance increasing piece is in contact connection with the pipe gallery pipeline. The arc-shaped resistance increasing piece is set as a semi-cylindrical structure and is made of rubber material.

[0011] Furthermore, the automatic locking structure includes an ejection block, an ejection slot, a first electromagnet, and a second electromagnet. The ejection slot is arranged on the side wall of the card slot of the base disk. The ejection block is snap-fitted and slid in the ejection slot. The first electromagnet is fixedly arranged on the ejection block. The second electromagnet is fixedly arranged in the ejection slot. The first electromagnet and the second electromagnet attract each other under the energized state.

[0012] Furthermore, the ejection block is fixedly connected to the ejection slot through a spring, and the ejection block is in contact connection with the bending bracket.

[0013] Preferably, a central controller is arranged inside the base disc. There is a signal between the central controller and the first electromagnet and the second electromagnet. The operator is equipped with a wireless remote control. There is a signal between the wireless remote control and the central controller. By operating the wireless remote control to send an instruction to the central controller, the central controller converts the instruction and then transmits it to the first electromagnet and the second electromagnet, making them energized and attracted, so that the ejection block loses the support for the bending bracket. When the edge touch plate slides horizontally and disengages from the pipe gallery pipeline, the arc-shaped resistance increasing piece reduces the fixed pressure on the side wall of the pipe gallery pipeline.

[0014] Furthermore, the clamping and fixing structure includes a positioning bracket, a support bracket, a cylinder and a pipe clamp. The positioning bracket is fixedly installed on the second chain. The support bracket is fixedly installed on the side wall of the positioning bracket. The pipe clamp is rotatably clamped on the positioning bracket and is concentrically arranged. The cylinder is fixedly arranged on the support bracket, and the connection between the cylinder and the pipe clamp is rotatably clamped.

[0015] Furthermore, the pipe gallery transport vehicle includes a crawler, a base, a lifting cylinder and a single-sided support plate. The crawler slides in the pipe gallery. The transmission equipment inside the base is connected to the crawler. The lifting cylinder is fixedly arranged on the side wall of one side of the base. The single-sided support plate is fixedly arranged on the side wall of the other side of the base. And the lifting cylinder is provided with a support plate with an arc-shaped structure that is rotatably clamped. The support plate is in contact connection with the pipe gallery pipeline, realizing the supporting effect on the pipe gallery pipeline. By raising the lifting cylinder, one side of the pipe gallery pipeline is tilted up, facilitating the insertion of the central column body in the single-sided automatic limit fixing device into the pipe gallery pipeline, and fixing and lifting one side of the pipe gallery pipeline.

[0016] During use, one side of the pipe gallery pipeline is fixed by the single-sided automatic limit fixing device, and then the middle part of the pipe gallery pipeline on the pipe gallery transport vehicle is clamped by the clamping and fixing structure. The first connection disc and the second connection disc are rotated respectively. After the height and angle of the pipe gallery pipeline are adjusted, it is docked with the already fixed pipe gallery pipeline. After being fixed by a flange, the external welded hanging bracket supports the pipe gallery pipeline, thereby connecting and installing the pipe gallery pipeline.

[0017] Furthermore, during installation, the track is installed at the middle position of the hanging bracket.

[0018] A pipe gallery large pipeline hoisting device provided by this solution has the following beneficial effects:

[0019] (1) By applying pressure on one side of the pipeline, the central column is inserted into the pipeline. The contact between the edge touch plate and the pipeline causes the spring-loaded protrusion to approach the bottom end of the bending bracket and contact the contact piece at the bottom end of the bending bracket. After being pressed, the bending bracket deflects, so that the other side of the bending bracket approaches the side wall of the pipeline, thereby realizing the clamping and fixing of the pipeline. Cooperating with two groups of electromagnets controlled by electricity, the control and limiting function of the bending bracket after flipping is realized, and the release of the fixed pipeline can be achieved through the operation method of the operator.

[0020] (2) The structure of the transmission equipment and the lifting device in the pipe gallery reduces the risk of casualties caused by the falling of the pipeline during manual lifting. Cooperating with the pipeline transportation equipment, the pipeline is tilted on one side, which improves the simplicity of the operation when the fixing equipment fixes the pipeline. When fixing the equipment, the supporting clamping and fixing structure improves the stability of transporting the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

The bending bracket 25 is clamped and rotatably arranged in the card slot of the base disk 24, and the bending bracket 25 is connected to the base disk 24 through a torsion spring. The touch piece 26 is hinged to one end of the bending bracket 25. The arc-shaped resistance increasing pieces 27 are linearly arranged on the other side of the bending bracket 25.

[0043] As Figure 7 , Figure 11 shown, the edge touch plate 21 and the touch plate chute 22 are fixedly connected by a spring.

[0044] As Figure 1 , Figure 7 shown, the elastic protrusion 23 is in contact connection with the touch piece 26, and the arc-shaped resistance increasing piece 27 is in contact connection with the pipe gallery pipeline 42. The arc-shaped resistance increasing piece 27 is set as a semi-cylindrical structure, and the arc-shaped resistance increasing piece 27 is made of rubber material.

[0045] As Figure 13 shown, the automatic locking structure 19 includes an ejection small block 28, an ejection slot 29, an electromagnet 30 and an electromagnet 31. The ejection slot 29 is arranged on the side wall of the card slot of the base disk 24. The ejection small block 28 is clamped and slid in the ejection slot 29. The electromagnet 30 is fixedly arranged on the ejection small block 28. The electromagnet 31 is fixedly arranged in the ejection slot 29.

[0046] As Figure 8 , Figure 11 , Figure 13 shown, the ejection small block 28 and the ejection slot 29 are fixedly connected by a spring, and the ejection small block 28 is in contact connection with the bending bracket 25.

[0047] As Figure 6As shown, the clamping and fixing structure 5 includes a positioning bracket 32, a support bracket 33, a cylinder 34 and a pipe clamping plate 35. The positioning bracket 32 is fixedly installed on the second chain 16, the support bracket 33 is fixedly installed on the side wall of the positioning bracket 32, the pipe clamping plate 35 is rotatably clamped on the positioning bracket 32 and is concentrically arranged. The cylinder 34 is fixedly arranged on the support bracket 33, and the connection between the cylinder 34 and the pipe clamping plate 35 is rotatably clamped.

[0048] When in use, the gallery pipe 42 is placed on the base 37 on the gallery transport vehicle 1, and the gallery transport vehicle 1 transports the gallery pipe 42 to the depth of the gallery 40. When it reaches the installation position in the gallery 40, the lifting cylinder 38 is extended to lift the support plate to lift one side of the gallery pipe 42, and the other side of the gallery pipe 42 is restricted by the single-sided support plate 39. The roller in the connecting plate 12 rotates, and the chain 13 is lowered to move the base disc 24 to the raised end of the gallery pipe 42. The central column 20 is inserted into the gallery pipe 42, and the connecting plate 12 is horizontally moved to a horizontal position on the track 6, and the gear 9 is meshed with the rack 7 to drive the connecting plate 12 to move to the horizontal position on the track 6. The connecting plate 11 moves horizontally, and at the same time, the external force is increased, and the edge touch plate 21 is made close to the pipe gallery pipe 42 by squeezing the base disc 24, so that the edge touch plate 21 is displaced; when the edge touch plate 21 moves laterally, the spring-pressing protrusion 23 presses the contact piece 26 at the bottom of the bending bracket 25, so that one end of the bending bracket 25 is deflected after being subjected to force. In the absence of external force, the ejection block 28 is in direct contact with the side walls on the left and right sides of the bending bracket 25. When there is an external force and the bending bracket 25 rotates, the ejection block 28 is ejected from the ejection slot 29 under the action of the spring, and the ejection block 28 presses against the rear wall of the bending bracket 25, so that the bending bracket 25 is relative to the ejection block 28. The arc-shaped resistance-increasing sheet 27 is only pressed on the side wall of the gallery pipe 42; then the connecting plate 2 15 is controlled to move to the middle position of the gallery pipe 42, and the chain 2 16 is extended until the pipe clamp 35 wraps the gallery pipe 42, and then the cylinder 34 is controlled to extend. Under the action of the cylinder 34, the pipe clamp 35 rotates with its engaging point on the positioning bracket 32 ​​as the center of the circle to clamp the gallery pipe 42; at this time, both ends of the gallery pipe 42 are fixed, and the chain 1 13 and the chain 2 16 are shortened, so that the gallery pipe 42 moves to a position parallel to the horizontal plane, and then the connecting plate 1 11 and the connecting plate 2 14 are controlled to move at the same linear speed along the direction of the track 6 to reach the fixed position. After placement, the hanging bracket 41 is installed and fixed at the bottom of the gallery pipe 42, so that the gallery pipe 42 is effectively fixed; when the fixation of the gallery pipe 42 is released, the cylinder 34 contracts, and the pipe clamp 35 loosens the clamping of the gallery pipe 42. Then, the electromagnet 1 30 and the electromagnet 2 31 are attracted under the action of the central controller, and the ejection block 28 is retracted into the ejection slot 29. The bending bracket 25 is acted upon by the torsion spring and rotates in the opposite direction. The bending bracket 25 causes the arc-shaped resistance-increasing sheet 27 to be separated from the fixation of the gallery pipe 42, and the pipe fixing docking device 2 is separated from the gallery pipe 42; then the above operation is repeated to complete the hoisting and fixation of the gallery pipe 42 in the gallery 40.
