Description

Technical Field

[0001] This utility model belongs to the technical field of civil engineering pipe storage racks, specifically relating to a civil engineering pipe storage rack. Background Technology

[0002] In civil engineering construction, pipes are important building materials, and their storage and management directly affect construction efficiency and safety. Traditional methods of storing pipes often involve stacking them on the ground or using simple wooden racks. These methods not only occupy a large area but also easily cause problems such as damage, deformation, and loss of pipes. With the expansion of project scale and the increase in the types of pipes, the demand for pipe storage racks is also increasing. Therefore, it is particularly important to design a storage rack with a reasonable structure, simple operation, and effective protection for pipes.

[0003] Most pipe storage racks on the market currently have the following shortcomings: First, they have complex structures, making installation and disassembly difficult and hindering rapid deployment on construction sites; second, they have a single fixing method, which cannot adapt to the storage needs of pipes of different diameters and lengths, thus limiting their versatility; and third, they lack stability, especially when used on complex terrain or uneven ground, as they are prone to tipping over and damaging the pipes. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a civil engineering pipe storage rack that solves the problems of complicated operation, difficulty in rapid deployment on construction sites, inapplicability to pipes of different diameters, low versatility, insufficient stability, and easy tipping, which can damage the pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a civil engineering pipe storage rack, comprising two connecting rods, each connected to a connecting seat at its top end. Limiting rods are fixedly mounted on the inner sides of the two sets of connecting seats. The limiting rods are connected to a clamping assembly, which includes a ratchet. The ratchet is rotatably connected to the limiting rod, and the limiting rod is rotatably connected to a pawl. The pawl engages with the ratchet. A second connecting rod is connected to the bottom surface of the ratchet. Movable arms are rotatably connected to both ends of the second connecting rod. Movable arms are rotatably connected to a sliding sleeve, which is fitted onto the outside of a sliding rod and slidably connected to it. Two sets of sliding rods are provided, each connected to a connecting seat. Each set of sliding rods is fitted with a clamping assembly. A spring has two ends connected to a connecting seat and a sliding sleeve on one side of the connecting seat, respectively. The bottom surface of the sliding sleeve is connected to a clamping component. The connecting rod one is connected to an unfolding support assembly, which includes a sleeve. The sleeve is slidably fitted on the outside of the connecting rod one. The two sides of the sleeve are rotatably connected to a support rod via pins. The support rod is rotatably connected to a movable arm two via pins. The end of the movable arm two away from the support rod is rotatably connected to the two sides of the connecting rod one via pins. The surface of the connecting rod one has a positioning slot one and a positioning slot two. The positioning slot one and the positioning slot two are adapted to insert a plug rod. The plug rod is slidably connected to the sleeve. A universal wheel is fixed at the bottom end of the connecting rod one.

[0006] The beneficial effects of this utility model are:

[0007] The operator only needs to hold the handle and turn the ratchet counterclockwise. The clamping component can clamp and limit the pipe through the clamping parts. At the same time, when it is necessary to disassemble the pipe, the operator only needs to pull the pawl outward. The clamping parts can be automatically unfolded by the elastic potential energy of the spring, quickly completing the disassembly of the pipe and restoring it to the initial state for easy use next time. The operation is simple and convenient for rapid deployment on the construction site.

[0008] The clamping assembly adopts a ratchet and pawl design. By adjusting the position of the ratchet and the clamping degree of the pawl, it is possible to clamp and fix pipes of different diameters and lengths.

[0009] The unfolding support assembly forms a stable triangular support structure through the combination of sleeve, support rod and movable arm II. At the same time, the support rod adopts a channel steel structure, which increases its load-bearing capacity and stability.

[0010] As a further improvement to the above technical solution: when the insertion rod is inserted into the positioning slot and the through hole opened on the sleeve, the side of the support rod is in contact with the side of the connecting rod, the bottom end of the support rod is not lower than the bottom end of the universal wheel, and the support rod is a channel steel structure.

[0011] The beneficial effects of this improvement are: when the support rod is folded, it can effectively reduce the standing area of ​​the device, without affecting the rolling of the casters, making it convenient to move the device.

[0012] As a further improvement to the above technical solution: when the insertion rod is inserted into the positioning slot 2 and the through hole opened on the sleeve, the bottom end of the support rod is not higher than the bottom end of the universal wheel.

[0013] The beneficial effects of this improvement are: when the support rod is extended, it can effectively increase the contact area between the device and the ground, provide oblique support for the device, and increase the stability of the device.

[0014] As a further improvement to the above technical solution: a mounting rod is provided at the center of the bottom surface of the ratchet, the mounting rod passes through the center of the connecting rod two, and the bottom end of the mounting rod rotates to engage with the connecting block.

[0015] The beneficial effect of this improvement is that it ensures the stability of the ratchet during rotation.

[0016] As a further improvement to the above technical solution: a mounting block is provided on the top surface of the end of the pawl facing the ratchet and connected to a tension spring, and the other end of the tension spring is connected to a positioning block installed on the limiting rod.

[0017] The beneficial effect of this improvement is that the elastic force provided by the tension spring ensures a tight contact between the pawl and the ratchet.

[0018] As a further improvement to the above technical solution: a handle is fixedly provided at the eccentric position of the top surface of the ratchet.

[0019] The benefits of this improvement are: the eccentric handle design reduces the force required to turn the ratchet, thereby reducing the operator's workload and improving work efficiency.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0028] like Figure 1-5 As shown, a civil engineering pipe storage rack includes a connecting rod 1. The top of the connecting rod 1 is connected to a connecting seat 3. Two sets of connecting seats 3 are fixedly provided with limiting rods 4. The limiting rods 4 are connected to a clamping assembly 5. The clamping assembly 5 includes a ratchet 501. The ratchet 501 is rotatably connected to the limiting rod 4. The limiting rod 4 is rotatably connected to a pawl 502. The pawl 502 engages with the ratchet 501. The bottom surface of the ratchet 501 is connected to a connecting rod 2 505. The two ends of the connecting rod 2 505 are rotatably connected to a movable arm 1 506. The movable arm 1 506 is rotatably connected to a sliding sleeve 508. The sliding sleeve 508 is fitted onto the outside of a sliding rod 503 and slidably connected to it. The sliding rod 503 is connected to the connecting seat 3. Springs 509 are fitted onto the outside of both sets of sliding rods 503. The two ends of the springs 509 are respectively connected to connecting rods 2 503 6 7 8 9 ... The seat 3 and the sliding sleeve 508 are connected to one side of the seat 3. The bottom surface of the sliding sleeve 508 is connected to the clamping member 6. The connecting rod 1 is connected to the unfolding support assembly 2. The unfolding support assembly 2 includes a sleeve 201. The sleeve 201 is slidably fitted on the outside of the connecting rod 1. The two sides of the sleeve 201 are rotatably connected to the support rod 206 through the pin. The support rod 206 is rotatably connected to the movable arm 2 through the pin. The end of the movable arm 2 away from the support rod 206 is rotatably connected to the two sides of the connecting rod 1 through the pin. The surface of the connecting rod 1 is provided with a positioning slot 1 203 and a positioning slot 204. The positioning slot 1 203 and the positioning slot 204 are adapted to insert the plug rod 202. The plug rod 202 is slidably connected to the sleeve 201. The bottom end of the connecting rod 1 is fixed with a universal wheel 205.

[0029] When the insertion rod 202 is inserted into the through hole opened in the positioning slot 203 and the sleeve 201, the side of the support rod 206 is in contact with the side of the connecting rod 1, and the bottom end of the support rod 206 is not lower than the bottom end of the caster wheel 205. The support rod 206 is a channel steel structure. When the support rod 206 is folded, it can effectively reduce the standing area of ​​the device, without affecting the rolling of the caster wheel 205, and facilitate the movement of the device.

[0030] When the insertion rod 202 is inserted into the through hole opened in the positioning slot 204 and the sleeve 201, the bottom end of the support rod 206 is not higher than the bottom end of the caster wheel 205; in the unfolded state, the support rod 206 can effectively increase the contact area between the device and the ground, provide oblique support for the device, and increase the stability of the device.

[0031] A mounting rod is provided at the center of the bottom surface of the ratchet 501. The mounting rod passes through the center of the connecting rod 505, and the bottom end of the mounting rod is rotatably engaged with the connecting block 504, thus ensuring the stability of the ratchet 501 during rotation.

[0032] The mounting block on the top surface of the pawl 502 facing the ratchet 501 is connected to the tension spring 507, and the other end of the tension spring 507 is connected to the positioning block 401 installed on the limiting rod 4; the elastic force provided by the tension spring 507 ensures close contact between the pawl 502 and the ratchet 501.

[0033] A handle is fixedly provided at the eccentric part of the top surface of the ratchet 501; the design of the eccentric handle makes the force required to turn the ratchet 501 less, reducing the labor intensity of the operator and improving work efficiency.

[0034] The working principle and usage process of this utility model are as follows: When using this device, it can first be moved to the designated position using the universal wheel 205. After reaching the designated position, the operator pulls the insertion rod 202 outward to disengage it from the sleeve 201 and the positioning slot 203, causing the sleeve 201 to slide downward. The insertion rod 202 is then fitted into the sleeve 201 and the positioning slot 204. At this time, the support rod 206 unfolds, and its bottom end contacts the ground, increasing the contact area between the device and the ground and enhancing the stability of the device. Then, the operator places the pipe between the two sets of clamping parts 6. The operator then holds the handle and rotates the ratchet 501 counterclockwise. The counterclockwise rotation of the ratchet 501 presses the pawl 502 outward, causing the pawl 502 to rotate outward. The tension spring 507 limits the maximum rotation angle of the pawl 502. When the ratchet 501 rotates, the connecting rod 505 causes the two sets of sliding sleeves 508 to slide relative to each other through the movable arm 506, which allows the clamping member 6 to move relative to the outside of the pipe to clamp the pipe. After the clamping member 6 has clamped the pipe, the handle is released. At this time, the pawl 502 is adapted to engage with the ratchet 501 in the appropriate position. At the same time, the tension spring 507 limits the minimum rotation angle of the pawl 502. The pawl 502 limits the ratchet 501, thereby completing the clamping of the pipe. When it is necessary to remove the pipe, the pawl 502 is pulled outward. At this time, the pawl 502 releases the limitation on the ratchet 501. The elastic potential energy of the spring 509 causes the sliding sleeves 508 to slide relative to each other, which drives the rotation of the ratchet 501. Then, the pawl 502 is released, and the clamping assembly 5 automatically returns to the initial state for easy use next time.
