Abstract
The utility model discloses a kind of bolt fixed base, be specifically related to one and be applied to Double chain scraper conveyor of China telescopic machine tail place, for the bolt fixed base of the baffle plate that is connected and fixed, fixing shovel board and telescopic machine tail.The technical problem solved be connected and fixed at present baffle plate, fixing shovel board and telescopic machine tail method operative difficulty greatly, required precision is high, and whole parts are easily scrapped, and assembling difficulty is large.The utility model bolt fixed base is provided with the bolt hole of up/down perforation, and it comprises top annulus and bottom annulus, and described top annulus is greater than bottom annulus.The utility model structure is dexterous, beautiful shape, and be effectively connected and fixed groove and telescopic machine tail, solid and reliable, effectively protects bolt, greatly reduces underground labour and changes bolt, changes the workload of fixed groove, improve productivity; Reduce component processing difficulty, reduce processing cost.
Description
Technical field
The utility model relates to a kind of connection set, is specifically related to one and is applied to Double chain scraper conveyor of China telescopic machine tail place, for the bolt fixed base of the baffle plate that is connected and fixed, fixing shovel board and telescopic machine tail.
Background technique
Be applied to Double chain scraper conveyor of China telescopic machine tail place at present, the method for the baffle plate that is connected and fixed, fixing shovel board and telescopic machine tail is mainly direct processes counterbore, construction bolt on parts, and two parts are fixed together.This method needs to hole on parts, and operative's difficulty is large, and required precision is high, and processing cost is very high; Stressed serious time, causing hole be out of shape, whole component exhaustion; Assembling difficulty is large.
Model utility content
The technical problems to be solved in the utility model is that be connected and fixed the at present method operative difficulty of baffle plate, fixing shovel board and telescopic machine tail is large; required precision is high; whole parts are easily scrapped, and assembling difficulty is large, provide that a kind of cost is low, assembling is simple, the bolt fixed base of proterctive equipment.
For achieving the above object, the utility model adopts following technical proposals: a kind of bolt fixed base, this bolt fixed base is provided with the bolt hole of up/down perforation, and it comprises top annulus and bottom annulus, and described top annulus is greater than bottom annulus.
Described top annulus and bottom circle ring inner wall are smooth cylndrical surface.
Adopt the utility model after said structure, structure is dexterous, beautiful shape, and be effectively connected and fixed groove and telescopic machine tail, solid and reliable, effectively protects bolt, greatly reduces underground labour and changes bolt, changes the workload of fixed groove, improve productivity; Reduce component processing difficulty, reduce processing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is practical view of the present utility model.
Embodiment
As shown in Figure 1, the utility model is provided with the bolt hole 3 of up/down perforation, and it comprises top annulus 1 and bottom annulus 2, and described top annulus 1 is greater than bottom annulus 2.
Described top annulus 1 and bottom annulus 2 inwall are smooth cylndrical surface.
In the course of the work, when slipper of coal producer goes to the operation interference of fixing shovel board place, first destroy fixed base, can bolt be protected, change fixed base, reduce coal miner's maintenance difficulty; Meanwhile, bolt fixed base, is equivalent to a large pad of bolt, makes evenly bolt strained; During installation, first mounting-fixing base, then construction bolt, reduce the labor intensity of operator; Assembling is simple, improves efficiency.
Claims (1)
1. a bolt fixed base, this bolt fixed base is provided with the bolt hole (3) of up/down perforation, it is characterized in that: described bolt block connects fixed groove and the telescopic machine tail of double chain conveyor, it comprises top annulus (1) and bottom annulus (2), and described top annulus (1) is greater than bottom annulus (2); Described top annulus (1) and bottom annulus (2) inwall are smooth cylndrical surface.
