Description
WEDGE-TYPE SELF-LOCKING CATCHING DEVICE OF BROKEN BELT CATCHER
I. Technical field
The present invention relates to a wedge-shaped self-locking capturing device for a broken belt catcher, belonging to machinery field.
II. Background Art
A belt conveyer is the most important production equipment in a coal mine, wherein the conveyer belt plays an important role in bearing and conveying materials and develops towards high power, large inclination, large conveyance volume, long distance and high speed, accompanying with occurrence of broken belt accidents, which causes damage to the equipment, blockage of the tunnel and shutdown of the mine. More severely, it will cause casualties, and the loss is uncountable.
The belt conveyer needs a certain broken belt protecting measure according to the regulations of the State, mainly for mounting the broken belt catcher. Most of the current capturing devices locally clamps the two idle sides of the conveyer belt of the belt conveyer, and provides a small capturing force, a skew acting position and a small clamping area. The capturing forces distributed on two sides of the conveyer belt cannot keep balance easily, which easily causes secondary longitudinal tearing of the broken conveyer belt. Moreover, randomness and adaptability for the position of the broken belt are not high, which goes against capturing of the broken belt.
III. Contents of the Invention
The present invention aims to provide a wedge-shaped self-locking capturing device for a broken belt catcher.
The present invention provides a wedge-shaped self-locking capturing device for a broken belt catcher, comprising a rack, a movable beam, a fixed beam, a cross bar and an oil cylinder; the movable beam, the cross bar and the oil cylinder are located above a conveyer belt, and the fixed beam is located below the conveyer belt; the movable beam is a quadrangular prism, and the cross section of the movable beam is in a right trapezoid shape; the cross bar is fixed to the upper end portion of the rack; the fixed beam and the cross bar are connected with the rack through a bolt; a cylinder barrel of the oil cylinder is connected with the cross bar, the other side of the cross bar is connected with a piston rod of the oil cylinder, the other end of the piston rod of the oil cylinder is fixed to the middle portion of the movable beam, guide blocks at two ends of the movable beam are respectively arranged in guide grooves on two sides of the rack; the guide blocks have small quadrangular prism structures; the guide blocks can move along the guide grooves; the guide blocks contact with the conveyer belt when sliding to the bottommost part; the contact face of the fixed beam, the movable beam and the conveyer belt is a rectangular plane; and the bottom surface of the movable beam is parallel to the bottom surface of the rack and is subjected to hatching knurling. Hatching knurling processing can increase the frictional force caused by mutual contact, so that all-sided integral lateral clamping capture can be performed to the broken belt, and the frictional force between the movable beam and the conveyer belt is increased to form wedge-shaped self-locking. The capturing frictional force is large enough to prevent secondary longitudinal tearing of the broken belt, and capturing is performed to the broken belt efficiently to guarantee safe operation of the belt conveyer.
In the above-mentioned device, the included angle a between the piston rod of the oil cylinder and the horizontal direction is equal to the wedge angle β, and β < 18.01°. The huge sliding force and the inertia force caused at the moment of breaking belt can be satisfied with the capturing force produced by self-locking of the mechanical structure. The movable beam slides along the guide groove of the rack through the guide block and matches with the fixed beam to lock up the broken conveyer belt with the huge frictional force caused according to the principle of wedgeshaped self-locking. The frictional coefficients between the movable bean and the rack and between the movable bean and the conveyer belt are μι, μ2 respectively; the positive pressure of the conveyer belt on the movable bean is Ni, the frictional force of the conveyer belt to the movable beam is Fi, the positive pressure of the rack on the movable beam is N2, and the frictional force of the rack to the movable wedge is F2; taking the movable wedge as a study object, 2 cos /7 + F sin ,0 = 0 , F, - F, cos β - sin β = 0 , wherein: 7V2/Z2=F2, the condition for the movable beam to clamp the conveyer belt is: M/zi^Fi; the wedge angle condition for the β < arctan—— movable beam to exert self-locking to the conveyer belt is: l+FiFz ; after looking up the machinery book, the frictional coefficient of rubber to the cast iron is 0.5 ~ 0.8; due to presence of coal flow on the conveyer belt in the actual use, it is equal to a lubricant that will reduce the frictional coefficient, taking μι =0.5; it is steel to steel friction between the movable beam and the rack, taking //2=0.15, β < 18.01° can be obtained, and the mechanical structure can be self-locked. The above explanation is applicable to any tension condition, and can further be applied to various materials with a greater frictional coefficient. No matter how large the sliding force and the inertia force caused by the broken belt, the movable beam can produce a balanced frictional force to complete reliable capturing. When the wedge angle is within 18°, the mechanical structure of the capturing device can form self-locking; the maximum stress on the rack is gradually decreased when the wedge angle is less than 12°, and gradually increase after the wedge angle is greater than 12°; the stress is minimum when the wedge angle is 12°, which means that the wedge angle selected to be 12° is reasonable under such a design, self-locking can be guaranteed and the produced stress is minimum.
In the device, the width of the movable beam is not less than that of the conveyer belt, belonging to all-sided integral lateral clamping capture that is different from the capturing device with local clamping. Therefore, the problems of small capturing area, insufficient braking force and secondary longitudinal tearing of the broken belt are efficiently solved.
In the device, the contact face of the slide block of the capturing device and the conveyer belt is a hatching knurling structure, and the contact side of the fixed beam and the conveyer belt is also a hatching knurling structure.
Benefits:
(1) the contact area between the movable beam and the conveyer belt is large, leading to all-sided lateral clamping capture;
(2) at the same time, textured finishing of the capturing wedge surface can increase the frictional force, which is beneficial to increase of the capturing force;
(3) the formed wedge-shaped self-locking clamps tighter and tighter, and the broken conveyer belt can be reliably captured;
(4) for the design of setting the angle a between the oil cylinder and the guide grooves and the rack of the capturing device to be equal to the wedge angle β, with permission of the structural strength and the conveyance intensity, no matter how large the sliding force and the inertia force caused by the broken belt, the slide blocks can produce a balanced frictional force, and the broken conveyer belt is clamped within a short time and is reliably captured;
(5) the rectangular plane surface of the movable beam is designed as a hatching knurling surface; the pressure produced by wedge-shaped self-locking is constant; increasing the degree of roughness of the contact face can increase the frictional force; the contact face of the fixed beam and the conveyer belt is also designed as a hatching knurling surface, so that the frictions of the upper and lower surfaces of the conveyer belt are increased, and the conveyer belt has uniform upper and lower frictional forces and is not easy to tear. Therefore, the capturing effect is guaranteed, and the requirement for the self-locking principle in the utility model is satisfied.
