Abstract

The utility model discloses a retrograde stopper for a cam column rubber belt, more particularly to a retrograde stopper for a plurality of cam column rubber belts symmetrically arranged on two sides of a rubber belt conveyer framework. The utility model comprises a box body, a press belt cam, a flow separating-type top plate, a top press plate, a cam replacement handle, a cam shaft, a support belt shaft, a support belt bearing, a cam connecting rod, a tension spring, a rubber retrograde sensor, as well as an electromagnet etc. When the rubber belt conveyor is in failure-free operation, the press belt cam is locked to the position with minimal radius by the cam connecting rod and the electromagnet, at the same time, the sealing supports arranged on two press belt cams propel the bearing play actions of bracket rubber belt and preventing the rubber belt from being wore. When the rubber belt retrogrades due to the broken belt or the slippage, the rubber belt retrograde stopper issues a directive, the electromagnetic acts to release the cam connecting rod, the press belt cam is rapidly dragged to the large-radius position by the tension spring and the cam connecting rod, so that the retrograding rubber belt is tightly pressed by the flow separating-type top plate, thereby stopping the rubber belt from retrogradation.

Description

The cam lap siding adhesive tape interceptor that drives in the wrong direction

Technical field

The utility model relates to a kind of travelling apron, specifically refers to be installed in be used to the holdout device that stops adhesive tape to drive in the wrong direction on the travelling apron.

Background technology

Travelling apron is used in the mine widely, harbour etc., is mainly used in all kinds of loose unpacked materials of transportation.In transportation, reason such as aging owing to adhesive tape, damaged, as to skid easily causes the adhesive tape broken belt or skids and drive in the wrong direction, drives in the wrong direction as can not in time stoping adhesive tape, will cause damage and destruction to equipment, personnel and production scene.The retrograde holdout device of adhesive tape substantially all is not installed at present, the worker that normally makes children inspection on the travelling apron.

In recent years, some travelling apron broken belts also occurred and arrest device, the structure that has is too complicated, and installation, maintenance cost height is difficult to promote; Though have simple in structure but braking force is not enough; The design defectiveness that has stops the material of transportation and the adhesive tape that weares and teares easily.

Summary of the invention

The purpose of this utility model provides a kind of for the cam lap siding adhesive tape that travelling apron prevents the adhesive tape broken belt or adhesive tape drives in the wrong direction when the skidding interceptor that drives in the wrong direction, this device symmetry is installed in two of travelling apron frame, when travelling apron normally moves, two pressure zone cams of file, are installed in two sealings on the pressure zone cam and entrust bearing and hold adhesive tape near the adhesive tape lower surface in the minimum radius position by cam link rod and locked with electromagnet.When adhesive tape because of broken belt or skid when driving in the wrong direction, two pressure zone cams that adhesive tape reserve motion sensor sends instruction-electromagnet and move-release cam link rod-file are drawn to the long radius position rapidly by extension spring and cam link rod, with the top pressing board of bypass type top board lower end the adhesive tape that drives in the wrong direction is compressed, thereby stop adhesive tape to drive in the wrong direction.

The utility model is realized with following technical scheme: a kind of cam lap siding adhesive tape interceptor that drives in the wrong direction, comprise casing, pressure zone cam, tape movement sensor, controller and electromagnetic valve, it is characterized in that: described casing is installed in the bottom of travelling apron frame, two camshafts that are parallel to each other are installed in the bottom of casing, and preceding pressure zone cam, back pressure zone cam sliding fit respectively are sleeved on the middle part of two camshafts; Pressure zone cam top, front and back is two cam link pins of vertical fixing respectively, and cam link rod two ends sliding fit respectively are sleeved on two cam link pins; The other end of cam link pin is installed and is entrusted bearing; On the cam coupled axle-pin before extension spring one end is sleeved on the pressure zone cam, the other end is fixed on the lower right side of casing; The outer end of pressure zone cam before cam resets and shakes hands to be vertically fixed on; The bypass type top board is by being bolted to the upper end of casing, and top pressing board is fixed on the lower surface of bypass type top board; Electromagnet is vertically fixed on the outside on casing top, and connects with controller and sensor by signal wire (SW), and the contact of electromagnet is attached to the upper surface of cam link rod.

Good effect of the present utility model is:

1, simple in structure, installation and maintenance are convenient.

2, adopt the file mode that the pressure zone cam is installed, satisfying under the prerequisite of braking force, pressure zone cam and bypass type top board are carried out the contact width miniaturized design, thereby reduce the bypass type top board with obstruction influence to the adhesive tape convey materials.

3, when travelling apron normally moves, the pressure zone cam is in the minimum radius position, enough spaces is provided for the adhesive tape of normal operation, is installed in two sealings on the protruding people of pressure zone simultaneously and entrusts the bearing bracket adhesive tape, prevents the adhesive tape wearing and tearing, prolongs adhesive tape service life.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the utility model structural representation;

Fig. 2 is the birds-eye view of Fig. 1.

Among the figure: 1, casing, 2, preceding pressure zone cam, 3, back pressure zone cam, 4, the bypass type top board, 5, top pressing board, 6, the cam handle that resets, 7, electromagnet, 8, camshaft, 9, entrust bearing, 10, the cam link rod, 11, extension spring, 12, the cam link pin.

The specific embodiment

As shown in Figure 1 and Figure 2, power 1

As shown in Figure 2: when travelling apron normally moves, preceding pressure zone cam 2 is locked in minimum radius position (position shown in the long and two-short dash line among Fig. 1) with back pressure zone cam 3 by cam link rod 10 and electromagnet 7, enough spaces are provided for the adhesive tape of normal operation, simultaneously, the bearing 9 of entrusting that is installed on two pressure zone cams plays the carriage adhesive tape, prevents the effect of adhesive tape worn-down.When adhesive tape because of broken belt or skid when driving in the wrong direction, adhesive tape reserve motion sensor sends instruction-electromagnet 7 and moves-release cam that pressure zone cam 2 is drawn to the long radius position with back pressure zone cam 3 rapidly by extension spring 11 and cam link rod 10 before the link rod 10-, with the top pressing board 5 on the bypass type top board 4 adhesive tape that drives in the wrong direction is compressed, thereby stop adhesive tape to drive in the wrong direction.Guaranteeing effectively to stop under the prerequisite of the retrograde braking force of adhesive tape, forward and backward

pressure zone cam

2,3 and bypass type top board 4 and top pressing board 5 can be carried out the contact width miniaturized design, the material direction of meeting of bypass type top board 4 and top pressing board 5 is designed to the stream line pattern inclined-plane at (material inflow end face) simultaneously, reduce stopping of bypass type top board 4 and 5 pairs of materials of top pressing board to greatest extent, avoid taking place material sun stream.
