Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a prefabricated drainage trough and a small well chamber clamp. Background Technology

[0002] Precast drainage troughs and small well chamber clamps are special tools used to fix and position workpieces during the production and installation of precast drainage troughs and small well chambers, so as to ensure processing or installation accuracy, improve production efficiency and safety.

[0003] Currently, construction projects using precast drainage channels all use slings or steel cables for installation and transportation. This can cause damage to the precast drainage channels and instability during transportation, which has a significant impact on construction quality and personnel safety. Repeatedly untying and untying the slings and cables can also affect the construction progress.

[0004] To address these issues, we provide a prefabricated drainage channel and a small well chamber clamp. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated drainage ditch and a small well chamber clamp. By using the cooperation of the first L-shaped clamp and the second L-shaped clamp, the existing technology of using slings or steel cables for installation and transportation of prefabricated drainage ditch in construction projects solves the problem that the prefabricated drainage ditch is damaged and unstable during the hoisting process.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a prefabricated drainage ditch and a small well chamber clamp, comprising a first sling plate, a second sling plate fixedly connected to one side of the first sling plate by a connecting pin, a first connecting rod movably connected between the first sling plate and the second sling plate, a second connecting rod movably connected to one side of the second sling plate, a first L-shaped clamping plate movably connected to one end of the first connecting rod, a second L-shaped clamping plate movably connected to one end of the second connecting rod, and anti-slip and wear-resistant clamping heads provided at one end of both the first and second L-shaped clamping heads, a clamping plate fixedly connected to one side of each anti-slip and wear-resistant clamping head, and a tension spring fixedly connected to the top of each anti-slip and wear-resistant clamping head.

[0008] The present invention is further configured such that a rope-tying plate is fixedly connected to the top of the first sling plate and the second sling plate, and an arc-shaped plate is fixedly connected to the inner cavity of the rope-tying plate. One end of the rope passes through the inner cavity of the rope-tying plate and is fixedly connected to the rope-tying plate through the arc-shaped plate.

[0009] The present invention is further configured such that a pin is movably connected between the first L-shaped clamping plate and the second L-shaped clamping plate, and hexagonal nuts are fixedly connected to both ends of the pin. The pin passes through the first L-shaped clamping plate and the second L-shaped clamping plate, and hexagonal nuts are screwed on both ends of the pin respectively, so that the first L-shaped clamping plate and the second L-shaped clamping plate are connected by the pin.

[0010] The present invention is further configured such that an anti-slip plate is fixedly connected to one side of the clamping plate, and an anti-slip strip is provided on one side of the anti-slip plate. The anti-slip structure composed of the anti-slip plate and the anti-slip strip can greatly improve the anti-slip performance of one side of the clamping plate and can better clamp the components.

[0011] The present invention is further configured such that bolts are connected through the surface of the anti-slip and wear-resistant chuck, and the first L-shaped clamp and the second L-shaped clamp are both connected through the bolts. The anti-slip and wear-resistant chuck is respectively fitted onto one end of the first L-shaped clamp and the second L-shaped clamp, and the anti-slip and wear-resistant chuck is fixed to one end of the first L-shaped clamp and the second L-shaped clamp with bolts, which facilitates the clamping of components later.

[0012] The present invention is further configured such that a partition is fixedly connected to the opposite side of the first L-shaped clamp and the second L-shaped clamp, and the surface of the partition is provided with a wear-resistant coating. The surface of the partition has good wear resistance, and when the first L-shaped clamp and the second L-shaped clamp rotate, excessive wear on their opposite surfaces can be avoided.

[0013] The present invention is further configured such that a movable pin is movably connected to one end of the first connecting rod, and one end of the movable pin penetrates into the inner cavity of the first sling plate. The movable pin at one end of the first connecting rod is inserted into the inner cavity of the first sling plate, and the first connecting rod is positioned on one side of the first sling plate by means of the movable pin.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model provides sufficient angle and space for the first L-shaped clamping plate and the second L-shaped clamping plate to clamp components by fixing the lifting rope to the binding rope plate on the top of the first lifting plate and the second lifting plate. It can flexibly adapt to prefabricated drainage channels or well chamber components of different specifications. When clamping components, it is only necessary to fasten the lifting rope to the first connecting rod and the second connecting rod, and at the same time place a set of clamps in a relaxed covering state on the side wall of the component. The clamping preparation can be completed without complicated adjustment, reducing the difficulty of operation.

[0016] 2. This utility model utilizes a scissor-like principle during lifting. The clamps automatically clamp the side walls of the component during the lifting process, ensuring a stable and reliable lifting process. After the component is lifted into place, the lifting ropes are loosened, and the clamp plates of the clamps are released accordingly, realizing the convenient operation of "lifting and tightening immediately, and releasing and loosening immediately". After completing one lifting operation, the clamps can be quickly moved to the next component to continue clamping and lifting, reducing auxiliary operation time. It is suitable for the batch installation of prefabricated components and significantly improves construction efficiency. Attached Figure Description
