Description

Technical Field

[0001] The utility model relates to the technical field of membrane wall splicing welding auxiliary equipment, in particular to a membrane wall splicing welding pitch control device. Background Art

[0002] Membrane water walls are composed of airtight panels welded together from flat steel and pipes. They ensure excellent furnace tightness and, for negative pressure boilers, significantly reduce furnace air leakage, improving combustion conditions. They also increase the effective radiant heating area, thereby saving steel consumption.

[0003] The existing membrane wall needs to be spliced and welded, which means that multiple tubes and symmetrical diaphragm flat steels are spliced together and welded. In the known technology, Chinese patent number "CN 217096454 U" mentions a membrane wall splicing welding pitch control device, in which a membrane wall tube row is fixedly installed on the bottom of the pitch control device body, and diaphragm flat steels are fixedly added to the upper part of both sides of the membrane wall tube row. The pitch control device for the membrane wall splicing welding is composed of two sets of profiling dies that are bonded together. 14-20 sets of semicircular holes are provided on each side of the two sets of profiling dies that are bonded together. After the pipes and flat steels are fixed by the two sets of profiling dies, the spacing between the pipes is limited by the mounting holes of the profiling dies. The profiling dies have a corresponding number of fixing bolt holes. When welding the pipes and the membrane flat steel, the device is installed at the end of the pipe, and welding is started after the bolts are tightened. In this way, the pitch size change caused by welding deformation can be effectively controlled, so that the pitch of the pipe reaches the standard value.

[0004] The above-mentioned membrane wall splicing welding pitch control device adopts bolts and other connection methods between the profiling molds, which requires workers to use external tools to disassemble and assemble. In addition, the semicircular holes in the profiling mold for placing pipes are fixed in the profiling mold. The spacing between the multiple semicircular holes cannot be adjusted, which reduces the scope of applicability.

[0005] In view of this, a membrane wall splicing welding pitch control device is provided to overcome the above-mentioned defects. Utility Model Content

[0006] In response to the problems in the related art, the present invention proposes a membrane wall splicing welding pitch control device to overcome the above-mentioned technical problems existing in the existing related art.

[0007] To this end, the specific technical solutions adopted in this utility model are as follows:

[0008] A membrane wall splicing welding pitch control device includes multiple mounting plates, which are connected by adjustment mechanisms, and the adjustment mechanisms are symmetrically arranged on both sides of the mounting plates. A placement plate is fixedly connected below the front surface of the mounting plate, and a scale value is set on the front surface of the placement plate. A braking mechanism is symmetrically arranged on the front surface of the mounting plate, and the front surface of the braking mechanism is connected to a connecting plate. A positioning mechanism is equidistantly arranged between the connecting plate and the placement plate.

[0009] Preferably, the adjustment mechanism includes a sleeve and a reset spring, the sleeves are symmetrically arranged on the left and right sides of the mounting plate, and a reset spring is arranged between the sleeves located on the same vertical line.

[0010] Preferably, the braking mechanism includes a brake groove, a brake screw, a brake block, a groove and a motor. The brake groove is symmetrically dug on the front surface of the mounting plate. A brake screw is provided at the bottom of the inner cavity of the brake groove. The outer wall of the brake screw is connected to the brake block through a thread. A groove is dug at the top of the brake groove, and a motor is provided in the groove.

[0011] Preferably, the top of the brake screw rod passes through the top of the inner cavity of the brake groove and extends into the groove, and the brake screw rod is connected to the motor.

[0012] Preferably, the connecting plate is arranged on the front surface of the brake block, and the connection between the brake block and the connecting plate is a fixed connection.

[0013] Preferably, the positioning mechanism includes a positioning block and a positioning ring. The positioning block is arranged between the placement plate and the connecting plate and is arranged at equal distances. The front surface of the positioning block is fixedly connected to the positioning ring.

[0014] This utility model has the following beneficial effects:

[0015] Compared with the existing technology, the membrane wall splicing welding pitch control device forms a new structure by combining multiple mechanisms such as the adjustment mechanism, the braking mechanism and the positioning mechanism. The multiple mounting plates are connected by the elastic drive of the return spring. Compared with the positioning method used for bolts and the like in the known technology, it is simpler and does not require staff to use external tools to disassemble and assemble. The components in the positioning end used for pipe positioning adopt a snap-fit installation method, and the spacing can be freely adjusted, which improves flexibility and scope of application.
