The trolleys used for spraying polyurethane in the prior art lack a fixing mechanism, which causes the steel pipe to roll off easily during the spraying process, endangering the safety of workers. At the same time, the worker is working hard to turn the steel pipe with his hands.
A thermal insulation pipe support fixing device including left and right moving trolleys is designed, and a clamping mechanism is installed on the trolley. The clamping mechanism consists of a vertical plate, a support plate, a clamping plate, a clamping block, a clamping cylinder and a synchronous shaft, which can clamp the steel pipe and allow it to rotate.
Through the use of the clamping mechanism, the steel pipe is firmly fixed during the spraying process, which improves safety, reduces the labor intensity of workers, and ensures the stability of the spraying process.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of thermal insulation pipes, and in particular relates to a thermal insulation pipe supporting and fixing device. Background Art
[0002] Prefabricated direct buried insulated pipes are composed of steel pipes (working pipes) for conveying media, polyurethane rigid foam plastic layers (insulation layers), and high-density polyethylene outer sleeves (outer protective layers). They are widely used in the insulation and cold preservation projects of central heating pipes, central air-conditioning pipes, chemical, pharmaceutical and other industrial pipes due to their advantages of low heat loss, good corrosion resistance and insulation performance, and quick and safe construction. The main process is to spray polyurethane on the surface of the steel pipe that has been derusted, and then insert an external protective pipe on the outside of the steel pipe, and then inject the foaming liquid of the insulation material into the gap between the steel pipe and the external protective pipe to complete the production of the insulation pipe. When spraying polyurethane on the surface of a steel pipe, the steel pipe needs to be suspended in the air to facilitate uniform spraying. At present, the method used by workers is to put the two ends of the steel pipe on a trolley and rotate the steel pipe for spraying. In the prior art, this trolley has no fixing mechanism, and only limits the position after the two ends of the steel pipe are overlapped. If the limit is forgotten, the steel pipe is easy to roll off the trolley and injure the workers during the spraying process. In addition, it is very laborious for workers to rotate the steel pipe by hand, so it is urgent to improve this trolley in the prior art. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0014] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0015] like Figure 1 and Figure 2As shown, the utility model discloses an insulation pipe supporting and fixing device, including left and right moving trolleys 1 with the same structure. The left and right trolleys have universal wheels at the bottom. The left and right moving trolleys are used in conjunction with each other. The left moving trolley is used to carry the left port of the steel pipe, and the right moving trolley is used to carry the right port of the steel pipe.
[0016] Specifically, a clamping mechanism is installed on the left and right moving trolleys respectively, and the clamping mechanism includes a vertical plate 2, a support plate 3, a left clamping plate 4, a right clamping plate 5, a left clamping block 6, a right clamping block 7, a clamping cylinder 8 and a synchronization shaft 9. The vertical plate is fixed on the trolley. In order to improve the stability of the vertical plate, the device is provided with a reinforcing beam 14 between the vertical plate and the left and right moving trolleys.
[0017] The support plate is fixed to one side of the vertical plate by bolts. A through hole 10 for the steel pipe to pass through is provided in the center of the support plate. Three rotating wheels 11 are provided at the bottom of the through hole along the axial direction of the through hole. The support plate is used to support the port of the steel pipe. When in use, the port of the steel pipe is overlapped on the three rotating wheels and can rotate by itself, thereby facilitating the spraying of polyurethane.
[0018] In order to keep the steel pipe stationary, in this device, the left clamp and the right clamp are located on the outside of the support plate, the left clamp block and the right clamp are respectively fixed on the left clamp and the right clamp, and the left clamp block and the right clamp block are respectively provided with clamping grooves 13. The upper parts of the left clamp and the right clamp are respectively connected to the two pistons of the clamping cylinder, and the clamping cylinder is fixed to the upper part of the vertical plate. The lower parts of the left clamp and the right clamp are slidably connected to the synchronous shaft through the guide sleeve 12, and the two ends of the synchronous shaft are fixed to the lower part of the vertical plate through the connecting seat. The clamping cylinder in this device is a customized cylinder, and the principle is still the traditional clamping cylinder principle, but the size is smaller and larger. Through the action of the two piston rods of the cylinder, the left clamp and the right clamp are driven to open and close, thereby driving the left clamp block and the right clamp block to clamp or loosen the two sides of the steel pipe.
[0019] When in use, the worker first lifts one end of the steel pipe into the through hole of the left moving trolley, and then lifts the other end of the steel pipe into the through hole of the right moving trolley. The clamping cylinder clamps both ends of the steel pipe and starts spraying polyurethane. After that, the clamping cylinder loosens and rotates the steel pipe, and then sprays the other side. After all spraying is completed, the steel pipe can be removed. The clamping mechanism of this device can fix the steel pipe during the spraying process to ensure the safety of the workers.
[0020] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
