Description

Technical Field

[0001] The utility model relates to the technical field of endless rope continuous traction vehicles, in particular to a rope pressing device for endless rope continuous traction vehicles. Background Art

[0002] The endless rope continuous traction vehicle is a common rail transportation equipment pulled by steel wire rope in underground coal mine tunnels. It is suitable for direct transportation of materials and equipment such as working face drifts, up and down mining areas, and concentrated rail tunnels under long distances, large inclinations, variable slopes, and large tonnage conditions without relocation. It is an ideal equipment to replace the traditional small winch relay and pulling transportation method to transport integral hydraulic supports and various equipment in mines. It can also be used in underground tunnels and on the ground of metal mines.

[0003] The traction rope is prone to drifting when the tractor is moving uphill, which will affect the safe operation of the tractor. In order to prevent the traction rope from shifting during the movement of the tractor, it is necessary to apply greater pressure to the traction rope on uphill sections. The existing tractor rope pressure device can only prevent the traction rope from shifting, but cannot adjust the tightness of the traction rope during movement. Utility Model Content

When the tractor is traveling on a slope, the balls are in contact with the piezoelectric sensors, and the piezoelectric sensors send signals to the driving motor. As the inclination angle of the road surface changes, the pressure on the pressure sensor also changes, and the signal strength sent is different, so that the traction rope maintains different tightness.

[0011] Furthermore, it also includes a left support wheel and a right support wheel;

[0012] The left support wheel and the right support wheel are rotatably connected to the fixed plate respectively, so as to prevent the traction rope from being displaced during the movement;

[0013] The side walls of the left support wheel and the right support wheel are provided with grooves for the traction rope to pass through;

[0014] The fixing plate is fixedly connected to the tractor by means of bolts.

[0017] Furthermore, the movable groove is two T-shaped grooves parallel to each other;

[0018] The openings of the movable groove are respectively located on the upper and lower sides of the fixed plate;

[0019] The movable racks are fixed on two adjacent side walls of the movable seat.

[0021] The movable racks are respectively meshed with the driving gears;

[0022] The moving directions of the moving seat are opposite, so that the upper pressure rope wheel and the lower pressure rope wheel move in opposite directions, thereby adjusting the tightness of the traction rope to keep the traction rope at a suitable tension.

[0023] Furthermore, the upper pressure rope wheel and the lower pressure rope wheel are both provided with rectangular grooves, and the traction rope passes through the rectangular groove between the upper pressure rope wheel and the lower pressure rope wheel;

[0024] The upper pressure rope wheel and the lower pressure rope wheel can apply pressure to the traction rope;

[0025] The upper pressing rope wheel and the lower pressing rope wheel are respectively rotatably connected to the side walls close to the ends of the two moving seats.

[0026] Furthermore, a cylindrical hollow cavity is provided inside the regulating switch;

[0027] The ball is spherical and can roll in the inner cavity of the regulating switch.

[0028] Furthermore, the driving motor is fixed on the back side of the fixing plate, a circular hole is formed on the fixing plate, and a rotating shaft of the driving motor passes through the hole.

[0029] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0030] The driving motor drives the moving seat to move in the opposite direction, drives the upper pressure rope wheel and the lower pressure wheel to move, and then applies pressure to the traction rope to keep the traction rope taut. This effectively solves the problem that the traction vehicle in the prior art is prone to rope drifting when going uphill, causing the traction rope to be displaced and affecting the safe operation of the traction vehicle. It is then possible to adjust the tightness of the traction rope according to the road surface on which the traction vehicle is traveling to avoid the rope drifting phenomenon.

When the tractor travels on a slope, the ball 13 contacts the piezoelectric sensor 12, and the piezoelectric sensor 12 sends a signal to the driving motor 11. As the inclination angle of the road surface changes, the pressure on the pressure sensor also changes, and the signal strength sent is different, so that the traction rope maintains different tightness.

[0042] Preferably, it also includes a left support wheel 2 and a right support wheel 9; the left support wheel 2 and the right support wheel 9 are respectively rotatably connected to the fixed plate 1, which can prevent the traction rope from being displaced during the movement; the side walls of the left support wheel 2 and the right support wheel 9 are provided with grooves for the traction rope to pass through; the fixed plate 1 is fixedly connected to the tractor by bolts.
