Description

Technical Field

[0001] The utility model belongs to the field of coal mining, in particular to a flexible support coal sweeper. Background Art

[0002] In coal mine engineering, due to the fissure water on the old pond side of the working face, the water from the cleaning pipeline of the kneading mold grouting machine along the empty lane at the outlet of the working face, and the cooling water of the working face equipment flowing to the tail section of the transfer machine, the water-mixed cargo reaches the upper warehouse belt (the upper warehouse belt belongs to the upward belt) through the transfer machine and the belt conveyor. It will adhere to the belt surface and increase the running resistance of the belt. Therefore, it is necessary to clean the coal slime attached to the belt surface. At present, a cleaning rubber is usually fixed under the belt, and the top of the cleaning rubber contacts the belt surface. When the belt moves, the cleaning rubber scrapes the belt surface to achieve the purpose of cleaning the belt. However, since the cleaning rubber wears quickly, once it is not replaced in time, it will not meet the requirements of cleaning the belt surface quickly. Frequent replacement of the cleaning rubber increases the labor intensity of belt operators and maintenance personnel, is not conducive to belt management, and seriously restricts safe production.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Flexible support coal sweeper, such as Figure 1 and Figure 2As shown, it includes a support frame 1 and a connecting seat 2 for mounting on a belt frame 9, and cleaning rubbers 3 extending horizontally along the support frame 1 are fixed on the front and rear sides of the support frame 1 along the longitudinal direction of the support frame 1. The cleaning rubber 3 is used to contact the belt 7 and clean the coal mud on the belt 7 during the movement of the belt 7. The cleaning rubber 3 is arranged on the front and rear sides of the support frame 1 along the longitudinal direction of the support frame 1, so that each part of the belt 7 is cleaned twice by the cleaning rubbers 3 arranged in front and behind, and the cleaning capacity is improved. The support frame 1 is used to install the supporting cleaning rubber 3. The connecting seat 2 is used to install the flexible support coal sweeper to the belt frame 9, so as to realize the installation of the flexible support coal sweeper at the required position. Vertically penetrating through holes 13 are respectively arranged at the left and right ends of the support frame 1 along the transverse direction of the support frame 1, and the full-thread bolt 4 passes through the through hole 13 of the support frame 1 and the connecting seat 2 from bottom to top in sequence and is connected to the nut 5; a telescopic spring 6 is arranged between the support frame 1 and the bottom end head of the full-thread bolt 4. The support frame 1 is hoisted on the connection seat 2 by the full-thread bolt 4, so that when the connection seat 2 is installed on the belt frame 9, the support frame 1 is hoisted on the connection seat 2, and the top of the cleaning rubber 3 fixed on the support frame 1 is centered and contacts the surface of the belt 7. A telescopic spring 6 is arranged between the support frame 1 and the bottom head of the full-thread bolt 4, and the telescopic spring 6 is freely arranged between the support frame 1 and the bottom head of the full-thread bolt 4, that is, in this embodiment, the top of the telescopic spring 6 is not directly connected to the support frame 1, and it is only in a compressed or natural length state, and does not appear in an elongated state. When the telescopic spring 6 is in a compressed state, its top acts on the support frame 1 upward, pushing the support frame 1 toward the belt 7, thereby ensuring that the cleaning rubber 3 contacts the surface of the belt 7. When the cleaning rubber 3 is worn, the cleaning rubber 3 is pushed toward the belt 7 by the elastic force of the telescopic spring 6, so that the worn cleaning rubber 3 contacts the surface of the belt 7, playing a cleaning role, thereby extending the service life of the cleaning rubber 3. When the cleaning rubber 3 is further worn until the telescopic spring 6 recovers its natural length, and the cleaning rubber 3 cannot clean the surface of the belt 7 due to wear, the nut 5 on the full-thread bolt 4 can be adjusted to lift the cleaning rubber 3 so that the cleaning rubber 3 contacts the surface of the belt 7. At the same time, the telescopic spring 6 is compressed again, so that the cleaning rubber 3 continues to perform the cleaning work, and the service life is greatly extended, which avoids frequent replacement of the cleaning rubber, alleviates the labor intensity of belt operators and maintenance personnel, and is beneficial to the management of the belt.

[0021] It should be noted that the full-thread bolt 4 may be only a full-thread screw, and the bottom end thereof may be a nut.

[0022] The connection seat 2 may be a shoulder pole beam supported on the belt frame 9. If a shoulder pole beam is used, the top of the full-thread bolt 4 needs to extend to the shoulder pole beam, which makes the full-thread bolt 4 longer and inconvenient to install. Figure 5As shown, the connecting seat 2 includes an upper clamping plate 21 and a lower clamping plate 22. Laterally along the supporting frame 1, the lower clamping plate 22 includes an inner section 22A aligned with the upper clamping plate 21 and an outer section 22B extending laterally outward from the upper clamping plate 21; four connecting bolts 23 are arranged between the inner sections 22A of the upper clamping plate 21 and the lower clamping plate 22, and the four connecting bolts 23 are located at four corners of a square, and are surrounded by the inner sections 22A of the upper clamping plate 21 and the lower clamping plate 22 and the four connecting bolts 23 to form a frame-shaped area for embracing the belt frame 9; the top end of the fully threaded bolt 4 is connected to the outer section of the lower clamping plate 22.

[0023] When installing this arrangement, the upper clamping plate 21 and the lower clamping plate 22 can be firstly used to hold the belt frame 9 up and down by four connecting bolts 23, so that the connecting seat 2 is stably installed on the belt frame 9. When the full-thread bolt 4 is subsequently installed, the belt frame 9 will not shake, and the installation is convenient. The top of the full-thread bolt 4 is installed on the lower clamping plate 22, the length is shorter, and the height of the nut 5 is reduced, which is convenient for adjustment. The arrangement of the inner section 22A and the outer section 22B of the lower clamping plate 22 can effectively avoid interference between the full-thread bolt 4 and the connecting bolt 23 or the belt frame 9 when installing.

[0025] The support frame 1 may be a rectangular truss, etc. In this embodiment, Figure 3 and Figure 4 As shown, the support frame 1 includes an L-shaped steel plate 11 longitudinally arranged on the front and rear sides and a horizontal plate 12 between the two L-shaped steel plates 11; one side of the L-shaped steel plates 11 on the front and rear sides is arranged vertically, and the other side is arranged horizontally and is located on the inner side of the vertically arranged side; the horizontal plate 12 is respectively fixed to the L-shaped steel plates 11 on the front and rear sides along the longitudinal direction. An L-shaped steel plate 11 is connected to each of the two ends of the horizontal plate 12, and the structure is simple. The L-shaped steel plate 11 can be made of bent steel plate, or it can be directly made of angle steel, which has good strength and can effectively support the cleaning rubber 3. In order to further improve the strength of the L-shaped steel plate 11, preferably, the horizontal plate 12 is vertically fixed to the middle of the vertically arranged side of the L-shaped steel plate 11.

[0026] The through holes 13 on the support frame 1 may be arranged on the horizontal side of the L-shaped steel plate 11 . For ease of installation, preferably, the through holes 13 on the support frame 1 are arranged on the horizontal plate 12 .

[0027] In order to further facilitate installation, the left and right ends of the horizontal plate 12 extend beyond the L-shaped steel plate 11 in the transverse direction; the through hole 13 is provided at the portion of the horizontal plate 12 extending beyond the L-shaped steel plate 11 .

[0028] In order to further improve the stability and reliability of the installation of the cleaning rubber 3, the inner side of the cleaning rubber 3 is in contact with the vertical edge of the L-shaped steel plate 11, and the outer side is in contact with the pressure plate 8. The pressure plate 8, the cleaning rubber 3 and the L-shaped steel plate 11 are tightened by connecting the bolt assembly.
