Abstract
Disclosed is an adjustable mining bottom plate rail clamping device, wherein a support seat is fixed on a mining bottom plate, clamping arms are installed on the support seat. The device is characterized in that the upper portions of the clamping arms are installed on the support seat via a hinge pin, simultaneously, a through hole is respectively disposed in the middle portions of the two clamping arms, one of the through holes is provided with threads, and a fastening screw and a fastening nut are arranged in the through holes. In an optimized scheme, a handle parallel to the hinge pin is further installed on the support seat and used for stopping rotation of the clamping arms. When in need of moving, the handle can be drawn out to loosen the clamping arms and rotate upwards, and then the handle is inserted to prevent the clamping arms from falling down to affect driving safety. The clamping arms are capable of moving along the hinge pin. The adjustable device overcomes problems that a conventional mining bottom plate rail clamping device is not suitable for rails with different rail distances, and when a machine is transferred from one coal mine to another for construction, the clamping device is often unusable so as to affect work schedule, thereby the adjustable device is suitable for different rail distances in underground coal mines, and leads work to be more convenient and quick.
Description
Technical field
The utility model relates to a kind of mining chassis rail clamping device that can regulate, is mainly used in the fixing of mining chassis.
Background technology
Coal mining is mechanization gradually, and machine is generally walked on the rail of down-hole, utilizes rail clamping device to be fixed on the rail during work, body instability when preventing work; At present, the used rail clamping device of underground equipment all is the down-hole rails that are suitable for specific gauge, the rail square of China's down-hole rail has 3 kinds, be respectively 900mm, 762mm and 600mm, rail clamping device often can't use when causing machine to transfer to the construction of another colliery from a colliery like this, has had a strong impact on job schedule.
Summary of the invention
The purpose of this utility model provides a kind of mining chassis rail clamping device that can regulate, this device can overcome the rail that traditional mining chassis rail clamping device can not adapt to different gauges, rail clamping device often can't use and influences the problem of job schedule when machine is transferred to the construction of another colliery from a colliery, can under coal mine, be suitable for different gauges, make work more convenient.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of mining chassis rail clamping device that can regulate, be fixed with bearing on the mining chassis, on this bearing, clamp arm is installed, it is characterized in that the top of described clamp arm is to be installed on the bearing, simultaneously by bearing pin, the middle part of described two clamp arms is provided with through hole, and one of them through hole is a tapped bore; In these two through holes, be provided with fastening screw and clamp nut.
In the above design of the present utility model, bearing is the supporting construction of clamp arm and bearing pin, with mining chassis weld together.Each fixing device all has left and right two clamp arms, and clamp arm adopts the 45# forging to make processing, and top is fixed on the bearing by bearing pin; Bearing pin adopts tempered steel to make, and is fixed on the bearing by spring cotter, mainly act as the support clamp arm.Process tapped bore on a clamp arm therein, so that fastening screw is tightened.Fastening screw one end processes screw thread, so that screw with clamp arm; The effect of clamp nut is that clamp arm is further tightened reinforcement again, prevents that fastening appearance is loosening.
The utility model has following prioritization scheme:
Install on bearing and also be provided with handle, this handle and bearing pin be arranged in parallel, and its effect is the upset that stops clamp arm; When needs move mining chassis, handle is extracted out, unclamp clamp arm and upwards upset, then handle is inserted, prevent that clamp arm from falling, and influences traffic safety.
The mounting means of described clamp arm and bearing pin is: mobile clamp arm can move along bearing pin.
A general mining chassis needs 2 rail clamping devices; The clamp arm of rail clamping device is designed to and can moves axially along bearing pin, and the stroke that moves can satisfy the requirement of different gauges; When running into the rail of different gauges at every turn, clamp arm is moved to the position clamping that needs get final product.During use clamp arm is moved along bearing pin, it is fixing behind the position suitable clamp arm and down-hole rail to be coincide, and screws with fastening screw and clamp nut and to get final product.
The utility model has overcome the rail that traditional mining chassis rail clamping device can not adapt to different gauges, rail clamping device often can't use and influences the problem of job schedule when machine is transferred to the construction of another colliery from a colliery, can under coal mine, be suitable for different gauges, make work more convenient.
