Description

Adjusting bracket for crossing conveying belt

Technical Field

The utility model belongs to the technical field of the technique of batch production concrete factory and specifically relates to a stride across regulation support of conveyer belt is related to.

Background

In the current social development, the consumption of concrete is always high whether bridges, roads or house buildings. Commercial concrete has come to be used in response to the rapid development of the construction industry. Commercial concrete is usually mass produced in a factory to form an automatic concrete batching system.

The existing automatic concrete batching system comprises a conveyor belt and a motor, wherein the motor is arranged below the conveyor belt; the materials are conveyed to a high place through the conveyor belt by using the motor, and the materials are added into the stirrer positioned at the high place for stirring. Conveyor belt material transport makes the plant more efficient, since conveyors are used to transport different materials, and almost all conveyors are located throughout the plant.

Because different materials are transported on the conveyor belt, the conveyor belt is distributed in a factory and occupies a large space, and a plurality of mixers in the factory are operated simultaneously in order to improve the production efficiency. All mixers require the use of conveyor belts for the transport of concrete production materials (such as sand, rocks, etc.) and support platforms are provided below each mixer platform. If two concrete mixer broke down simultaneously, if there is the existence of conveyer belt between the supporting platform that is used for two concrete mixer, constructor need follow a supporting platform from top to bottom, repairs the mixer on another supporting platform again, leads to inefficiency.

As shown in fig. 5, in order to solve the above problem, a ladder frame 30 is provided above a conveyor belt between two support platforms in the prior art. The two support platforms are designated as platform one 28 and platform two 29, respectively. The ladder frame 30 comprises a flat plate and frame bodies 24 fixed to both ends of the flat plate 8, and the two frame bodies 24 are supported on the first platform 28 and the second platform 29, respectively. The worker can reach the first platform 28 through the steel ladder 27 erected between the first platform 28 and the ground, and then cross the conveyor belt through the ladder frame 30 to reach the second platform 29, so that the worker can conveniently reach the other supporting platform from one supporting platform, and the working efficiency of the worker is improved.

The above prior art solutions have the following drawbacks: because the height difference between the platforms at the two sides of the conveyor belt is uncertain, the height of the frame body of the ladder frame needs to be selected according to the height difference of the first platform and the second platform on the spot, and then the two frame bodies are welded at the two ends of the flat plate. When the height difference between two supporting platforms is different, the ladder frame of different models just needs to be made, and the ladder frame can not be applicable to the frame between the different platforms in a flexible way promptly.

The limiting groove 7 is provided with a handrail 25. The handrail 25 of each side comprises a handrail rod 9 and a plurality of rest bars 10 evenly arranged on the handrail rod 9, all the rest bars 10 being arranged perpendicular to the handrail rod 9. One end of the supporting rod 10 far away from the grab rail 9 is inserted into the limiting groove 7, and a fixing bolt 15 corresponding to the supporting rod 10 is arranged on the side wall of the limiting groove 7 in a penetrating mode. After the fixing bolt 15 is tightened, the fixing bolt 15 abuts against the side wall of the hand-rest brace 10, thereby locking the position of the hand-rest brace 10.

Referring to fig. 1 and 4, in order to improve the safety of the user walking on the flat plate 8, a plurality of anti-slip lines 11 are provided at intervals on the upper surface of the flat plate 8. In order to improve the structural strength of the flat plate 8, two reinforcing bars 21 are fixed to the lower surface of the flat plate 8 so as to intersect with each other, and four ends of the reinforcing bars 21 correspond to four corners of the flat plate 8.

The implementation principle of the embodiment is as follows: the positioning bolt 17 is loosened, and the straight rod 1 is rotated to adjust the angle between the straight rod 1 and the flat plate 8. The positioning bolts 17 are then passed through the appropriate bolt holes 18 to secure the positioning bolts 17 to the plate 8. The other frame 24 is adjusted as above. Then, the adjusting bolt 19 is loosened to adjust the distance between the straight rod 1 and the sleeve 4, and the length formed by combining the straight rod 1 and the sleeve 4 is changed. The adjusting bolt 19 is then tightened to insert it into one of the holes 2. The supporting rod 10 is inserted into the clamping groove 12, and the supporting rod 10 is locked by the fixing bolt 15. The steps of adjusting the angle between the straight rod 1 and the flat plate 8 and adjusting the length between the straight rod 1 and the sleeve 4 can be replaced by a front-back sequence.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
