Abstract

The utility model relates to a colliery belt protection technical field specifically discloses a novel coal piling protection device of end belt, the device includes the mount, and signal sensor and action actuating mechanism constitute. With the development of science and technology, the unattended equipment appears, the complete protection of the belt is particularly important in the production link, and the traditional eight-protection of the belt can not meet the actual production link. In actual production, the most feared is that after the belt is torn and the protection of head coal pile is lost, no backup protection is provided to cause the accident expansion, and the problem that the belt is damaged due to the fact that the belt is too long and the condition that the patrol is not in place in the traditional coal mine construction site is solved.

Description

Novel coal piling protection device for bottom belt

Technical Field

The application relates to the technical field of coal mine belt protection, and particularly discloses a novel coal piling protection device for a bottom belt.

Background

In the process of coal mine safety construction, it is stipulated that protective devices for preventing slipping, deviation, coal piling, tearing and the like must be arranged on conveyor belt equipment, and meanwhile, a temperature and smoke monitoring device and an automatic water spraying device are required to be arranged.

However, in an actual construction site, because the length of the belt reaches hundreds of meters or even thousands of meters, manpower cannot patrol all the time, particularly, a coal drop point is not easy to observe, tearing and backup protection of the coal drop point are very important, and the belt can be damaged due to coal drop accumulation.

Therefore, the inventor provides a novel coal piling protection device for a bottom belt so as to solve the problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve traditional colliery job site in, because there is the condition of patrolling and examining not in place in the belt overlength, lead to the coal breakage to pile up the problem of damaging the belt.

In order to achieve the above object, the utility model discloses a basic scheme provides a novel coal piling protection device of end belt, including fixed bolster, actuating mechanism, with the signal sensor of fixed bolster rigid coupling and the sweeper of locating end belt up end, the fixed bolster is located one section rigid coupling in end belt below and has the horizontally pivot, the fixed bolster include rotate the sleeve pipe of being connected with the pivot and with the commentaries on classics board of sleeve pipe outer wall rigid coupling, sweeper, actuating mechanism and signal sensor set gradually backward in the past.

The principle and effect of this basic scheme lie in:

the utility model discloses when the end skin has the return coal, the sweeper blocks that the coal cinder flows to end skin below, after piling up and reacing the set position, the long-pending coal will promote the commentaries on classics board in the actuating mechanism, change the board and will revolute the rotation of axes through the sleeve pipe, change the board and will arrive signal sensor response department, thereby make signal sensor signals stop the belt operation, thereby in having solved traditional colliery job site, because the belt overlength exists and patrols and examines the not in place condition, lead to the coal breakage to pile up the problem of damaging the belt.

Furthermore, limiting rings are arranged on the rotating shaft and positioned on two sides of the sleeve. The sleeve is prevented from falling off from the rotating shaft by the limiting ring.

Furthermore, a baffle plate is fixedly connected to the side wall of the rotating plate. The sensing area of the signal sensor can be increased through the baffle.

Further, the fixed support is angle steel. The angle steel is more economical and practical.

Further, the fixed support is made of round steel. The round steel is used for facilitating welding of the positioning actuator and the signal sensor.

Further, the rotating shaft is fixedly connected to the position 200mm below the bottom belt. The lower end surface of the bottom belt is prevented from rubbing with the rotating shaft.

Furthermore, both ends of the sweeper are positioned outside both sides of the upper end of the bottom belt. Can sweep the coal dust on the upper end surface of the bottom belt completely.

Further, the sweeper is arranged obliquely. The coal dust is guided, and the coal dust can be conveniently separated from the bottom belt.

Further, the rotating plate is rectangular as a whole. The bottom end of the rectangular rotating plate has a larger contact area with the coal dust below.

Furthermore, a supporting structure for mounting the signal sensor is fixedly connected to the fixing support. The function of auxiliary fixing of the signal sensor is achieved.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

The following is further detailed by the specific embodiments:

reference numerals in the drawings of the specification include: the cleaning device comprises a bottom belt 1, a fixed support 2, a signal sensor 3, a rotating plate 4, a sleeve 5, a baffle 6, a rotating shaft 7, a sweeper 8 and a belt frame 9.

The embodiment of the novel bottom belt coal piling protection device is shown in figure 1, and the novel bottom belt coal piling protection device comprises a fixing support 2, an actuating mechanism and a signal sensor 3, wherein the bottom belt 1 is installed between belt frames 9, the fixing support 2 can be made of 40mmx3 angle steel or round steel with the diameter of 10mm, the length of the fixing support 2 is 400mm, the fixing support 2 is integrally installed on one side of the bottom belt 1, and the top end of the fixing support 2 exceeds the height of the bottom belt 1 and is connected with the belt frame 9 for installing the bottom belt 1;

the fixing support 2 is positioned at one section below the bottom belt 1, a rotating shaft 7 is welded at a position 200mm away from the lower surface of the bottom belt 1, the rotating shaft 7 is horizontally welded at one side of the fixing support 2 facing the bottom belt 1, the whole length of the rotating shaft 7 is about 300mm, two limiting rings are further welded on the rotating shaft 7, and an executing mechanism is installed between the limiting rings;
