Description

Technical Field

[0001] The utility model belongs to the technical field of pulverized coal furnaces, in particular to a unit assembly bracket for pulverized coal furnaces. Background Art

[0002] The pulverized coal boiler is a boiler equipment that uses pulverized coal as fuel, and the unit assembly bracket is a bracket used to install and support the pulverized coal boiler.

[0003] Due to the large size and numerous components of the pulverized coal furnace, power plants need to use unit assembly brackets to install and support the pulverized coal furnace. During this process, the legs, cones, and ribs are welded according to the marked positions.

[0004] However, during the entire unit assembly process, precise positioning is required, and the stability of the bracket is particularly important. Any slight instability will affect the installation of the entire pulverized coal furnace, so it needs to be improved. Summary of the Invention

[0005] The purpose of the utility model is to improve the problem of reduced equipment assembly quality due to lack of stability of the bracket during the unit assembly construction of the pulverized coal furnace, and to provide a unit assembly bracket for the pulverized coal furnace.

[0006] The utility model is achieved through the following technical solutions:

[0007] A unit assembly bracket for a pulverized coal furnace includes a main rod and a base placed at the bottom of the main rod, the side walls of the main rod are provided with a first connecting rod, a second connecting rod and a third connecting rod in the up and down directions, and the two side walls of the main rod are provided with a connecting groove body, the first connecting rod, the second connecting rod and the third connecting rod are connected at one end and provided with a first connecting piece, the first connecting rod, the second connecting rod and the third connecting rod are provided with a second connecting piece at one end away from the first connecting piece, the outer side walls of the first connecting piece and the second connecting piece are respectively abutted against the inner side walls of the corresponding connecting groove body; the first connecting piece, the second connecting piece and the connecting groove body are all provided with fixing holes, and the corresponding fixing holes are provided with fixers.

[0008] By adopting the above technical solution, the main pole is fixed to the ground through the base; the intersecting ends of the first connecting rod, the second connecting rod and the third connecting rod overlap on the first connecting piece, and the ends away from the first connecting piece are connected to their respective second connecting pieces, and the connecting pieces are inserted into the connecting groove body to achieve a stable connection between the two main poles; the three connecting rods of the first connecting rod, the second connecting rod and the third connecting rod are at a certain angle, and every two connecting rods and the main poles can form a triangular structure, which effectively enhances the stability of the connection between the main poles; after the outer wall of the connecting piece is pressed against the inner wall of the connecting groove body, the position of the connecting piece is adjusted so that the fixing hole of the connecting piece and the fixing hole of the connecting groove body overlap, and then the fixer is inserted into the fixing hole to fix the connecting piece, effectively preventing the connecting piece from detaching from the connecting groove body.

[0009] Furthermore, an elastic member connected to the fixer and used to insert the fixer into the fixing hole is provided on the outer side wall of the connecting groove body at the fixing hole.

[0010] By adopting the above technical solution, one end of the elastic member is connected to the outer side wall of the connecting groove body, and the other end is connected to the fixer. At the same time, the fixer is wrapped by the elastic member. When the connecting piece is not inserted into the connecting groove body, the fixer remains in a state of passing through the fixing hole on the connecting groove body, and the elastic member does not undergo elastic deformation. When the connecting piece needs to be inserted, the operator pulls the elastic member, and the fixer moves with the elastic member until it is disengaged from the fixing hole. After inserting the connecting piece into the connecting groove body and adjusting the fixing holes of the two to the appropriate position, the elastic member is released. Under the action of elastic force, the fixer is pushed and reinserted into the fixing hole. By pulling the elastic member, the insertion and exit of the fixer from the fixing hole can be efficiently controlled.

[0011] Furthermore, the outer side wall of the connecting groove body is provided with a pull box for placing the elastic member and the fixer, the elastic member is provided with a connecting rope at one end away from the fixer, and the pull box is provided with a pull hole for the connecting rope to pass through on the side away from the connecting groove body.

[0012] By adopting the above technical solution, one end of the pull box is fixedly connected to the connecting groove body for storing the elastic part and the fixer, which is convenient for the operator to fix the connecting piece and the connecting groove body, and provides wind and rain protection for the fixer and the elastic part during use; one end of the connecting rope is outside the pulling hole, and the other end passes through the pulling hole and is connected to the elastic part. The operator controls the degree of elastic deformation of the elastic part through the connecting rope, thereby controlling the fixer to insert or leave the fixing hole; the pulling hole makes it easy to ensure that the fixer can be easily moved and is always not affected by the pulling direction of the operator.

[0013] Furthermore, a handle is provided at one end of the connecting rope that passes through the pull hole and is away from the elastic member.

[0014] By adopting the above technical solution, the handle can facilitate the operator to pull the draw rope, while preventing the draw rope from being retracted into the draw box, making it difficult to move the fixer.

[0015] Furthermore, a groove is provided on the outer surface of the handle.

[0016] By adopting the above technical solution, the groove on the handle is ergonomically designed, making it easier for operators to pull the handle.

[0017] Furthermore, a rubber pad is provided on the surface of the groove.

[0018] By adopting the above technical solution, when the operator pulls the handle, the rubber pad plays an anti-slip role.

[0019] Furthermore, the fixer is provided with a guide at one end away from the elastic member.

[0020] By adopting the above technical solution, the guide adopts a conical structure, which can prevent the end of the fixer away from the elastic member from hitting the edge of the fixing hole during movement, making it easier for the fixer to enter the fixing hole quickly and accurately, thereby improving work efficiency.

[0021] Furthermore, a support plate is provided at the junction of the bottom of the connecting trough body and the main rod.

[0022] By adopting the above technical solution, the support plate supports the connecting trough body, preventing the connecting trough body from being deformed due to long-term pressure, and playing a stabilizing role.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1) Every two main rods are connected by the first connecting rod, the second connecting rod and the third connecting rod. The three connecting rods are connected at different angles. Every two connecting rods and the main rods form a triangular support, which enhances the stability between the connecting rods.

[0025] 2) By inserting the connecting pieces at both ends of the first connecting rod, the second connecting rod and the third connecting rod into the connecting groove body and fixing them with a fixer, the connecting pieces can be stably fixed by the fixer and will not deviate under the action of external force.

[0026] 3) The support plate provided at the junction of the bottom of the connecting trough and the main rod can effectively support the connecting trough to ensure the stability of the connection between the main rods. BRIEF DESCRIPTION OF THE DRAWINGS
