Description

The present invention relates to the field of pipe production technology, and specifically to a fixed support for laying pipes.

Piping is a device for transporting a fluid containing gas, liquid, or solid particles composed of tubes, tube couplings, valves, etc., and piping is widely used because of its unique characteristics. .. Plumbing has a wide range of uses, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic work, various machinery and equipment. And construction of pipes to transport solid slurry, including pipe route work, station work and pipe attachment work, and pipe work in a broad sense also includes supply of equipment and facilities, in which pipe laying There are two types of construction, above-ground (fictitious) laying and underground laying. Underground laying refers to the laying method in which pipes are laid underground, because it does not affect the appearance of the city or traffic. , It is a laying method widely used for urban centralized heat supply piping. Underground laying is also divided into drainage ditch laying, direct burial laying, sleeve laying and tunnel laying. However, in the process of laying pipes, the following problems exist:
Commonly seen pipe laying equipment can only handle foundations with a certain depth, and cannot function if the foundations are above or below the certain range, and pipe laying generally involves piping. The method of mounting one by one is adopted, and the efficiency is low and the stability of the entire device during mounting is low.
In the process of laying the pipe, the weight of the laying device and the entire pipe is mainly concentrated on the upper end surface of the foundation resistance, and the inner wall surface of the foundation resistance is extremely large, whether it is a vertical structure or an inclined structure. Due to the pressure, the possibility of deformation or dehiscence is greatly increased.

A plate is provided, and the transmission mechanism is symmetrically attached to the lower end surface of the base plate. The intervention mechanism is symmetrically attached to the central portion of the end face, and the intervention mechanism is located between the two transmission mechanisms.

The base plate has a structure that can be expanded and contracted, and a rectangular groove is formed on the left end surface of a fixed end of the base plate, and an active end is slidably attached to the inside of the rectangular groove. Electric sliders are symmetrically attached to the right ends of the front and rear end surfaces at the ends, and the electric slider and the inner wall surface of the rectangular groove are slidably connected to each other. Before laying the pipe, the electric slider moves the active end to the left or right according to the size of the foundation, and the active end is attached to the active end with the transmission mechanism and the interposition mechanism. By synchronously moving the above, the distance between the transmission mechanisms and the distance between the interposition mechanisms can be adjusted to meet the demand for laying pipes on different foundations.

The transmission mechanism includes a fixed block, a first linear actuator, a standing plate, a fixed shaft, a turntable, and a pulley, and an upper end of the fixed block is attached to a lower end surface of the base plate. The first linear actuator is symmetrically attached to the lower ends of both front and rear ends of the fixed block, and the standing plates are symmetrically provided on both front and rear sides of the fixed block, and the standing plates are arranged symmetrically to the left and right.

Attached, the mandrel is slidably attached to the lower end of the turntable, the pulley is attached to the mandrel at the lower end of the turntable, and when the foundation resistance is deep, the first linear actuator is said. Rotate the turntable outward so that the pulley therefore slides outward, which causes the base plate to be lower than the upper end surface of the base plate, thereby being sandwiched by the interposition mechanism and inserted into the base resistance. The situation where the length of the pipe to be installed becomes long and the pipe cannot be installed in the specified position is avoided.

The upper end of the third linear actuator is connected to the lower end surface of the connection plate. The third linear actuator pulls the pinching claw upward to open the pinching claw to match the pinching target pipe, and the third linear actuator pushes the pinching claw downward to pinch the pipe. The second linear actuator pushes the connecting plate downward, the connecting plate moves the holding claw synchronously by the third linear actuator, and the pipe is positioned at an internal corresponding position in the foundation resistance.

As a preferred technical solution of the present invention, a rectangular block is attached to the middle portion of the lower end surface of the connection plate, and a rectangular through groove is formed in the middle portion of the left end surface of the rectangular block.

Connected, the inner right end of the U-shaped locking base is slidably connected to the front end of the mandrel in the rotating rod. At the same time that the second linear actuator pushes the connecting plate downward, the rectangular block moves the rotating rod synchronously, and the push plate stops moving when the outer end surface comes into contact with the inner side wall of the foundation. In the process up to this point, the push plate moves in close contact with the inner wall surface of the foundation resistance, and at the same time, the push plate acts as a support for both sides of the foundation resistance and at the same time assists in fixing and guiding the positioning of the pipe mounting. When the inner wall surface of the foundation is an inclined surface, the U-shaped locking base is manually pulled out, the rotating rod is rotated by a certain angle, and the U-shaped locking base is engaged again.

That is, the compression spring and the first linear actuator can maintain the turntable in a force equilibrium state, thereby improving the degree of stability of the pipe laying fixed support base.

However, by supporting different sizes of foundations and adopting a rotatable structure, it is possible to lay pipes for foundations with inclined inner walls.

It reduces the damage to the foundation resistance caused by the push plate and reduces the incidence of dents inside the foundation resistance.

The cooperation between the rotating rod, the U-shaped locking base, and the angle meter in the present invention adjusts the tilt angle of the rotating rod, further increases the adaptability of the support base of the present invention, and at the same time, the user can adjust the angle.
