Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The embodiment of the utility model provides a buffer shock absorbing device and a drilling vehicle system, which can ensure the stability of the mining hanging rail type drilling vehicle during the travel process.

[0021] The present invention is further described in detail below with reference to the accompanying drawings.

[0022] See also Figure 1 As shown, a buffer shock absorbing device and a drilling vehicle system provided in this embodiment include a buffer mounting seat 11, a buffer assembly 12 and a moving assembly 13, wherein the moving assembly 13 includes a connecting base plate 131 and a moving portion 132; the bottom of the buffer assembly 12 is fixedly connected to the first side of the buffer mounting seat 11, the connecting base plate 131 is fixedly connected to the top of the buffer assembly 12, the moving portion 132 is movably connected to the connecting base plate 131, and the rotation range of the moving portion 132 around the connecting base plate 131 is 300 degrees to 360 degrees.

[0023] Among them, the buffer component 12 is installed above the buffer mounting seat 11, and the bottom fixed end of the buffer component 12 is fixedly connected to the first side of the buffer mounting seat 11. The first side of the buffer mounting seat 11 is the side of the buffer mounting seat 11 facing the tunnel roof, and the second side of the buffer mounting seat 11 is the side of the buffer mounting seat 11 facing the drilling vehicle. The connecting bottom plate 131 and the top of the buffer component 12 are fixedly connected by welding, and the moving part 132 is movably connected to the connecting bottom plate 131. The moving part 132 can make a 300-degree curved motion and / or a 360-degree circular motion around the connecting bottom plate 131 on the connecting bottom plate 131, thereby making the structure of the buffer shock absorbing device more solid and facilitating the device itself to adjust the direction of travel.

[0024] The utility model provides a buffering and shock absorbing device and a drilling vehicle system, comprising a buffering mounting seat, a buffering assembly and a moving assembly, the moving assembly comprising a connecting bottom plate and a moving part, the bottom of the buffering assembly is fixedly connected to the first side of the buffering mounting seat, the connecting bottom plate is fixedly connected to the top of the buffering assembly, the moving part is movably connected to the connecting bottom plate, and the rotation range of the moving part around the connecting bottom plate is 300 degrees-360 degrees; in this way, when the drilling vehicle travels on the hanging rail to the protruding part of the uneven position such as the tunnel wall or the top plate, the buffering assembly and the moving part can buffer and absorb the shock of the drilling vehicle while adjusting the traveling direction of the drilling vehicle in time according to the terrain, which can reduce the influence of the tunnel terrain on the drilling vehicle, thereby improving the working efficiency of coal mine work.

[0025] See also Figure 1 In order to increase the buffering effect of the buffering and shock absorbing device 10 on the force acting on the drilling vehicle, in some embodiments, the buffer assembly 12 includes a first buffer structure 121 and a second buffer structure 122; the fixed end of the second buffer structure 122 is fixedly connected to the buffer mounting seat 11, the first buffer structure 121 is vertically fixed to the free end of the second buffer structure 122, and the moving assembly 13 is arranged at the top of the first buffer structure 121 and is movably connected to the second buffer structure 122; wherein, the stiffness of the first buffer structure 121 is less than the stiffness of the second buffer structure 122, when the force on the first buffer structure 121 reaches the limit, the first buffer mechanism 121 can transfer the residual force to the second buffer structure 122, and when the first buffer structure 121 reaches the compression limit, secondary buffering and shock absorption are performed, thereby realizing the buffering effect of double shock absorption.

[0026] The lowest deformation stiffness threshold of the first buffer structure 121 may be slightly smaller than the highest deformation stiffness threshold of the second buffer structure 122 , wherein the deformation of the first buffer structure 121 and the second buffer structure 122 refers to elastic deformation.

[0027] See also Figure 1In order to enhance the structural strength of the buffer structure, in some embodiments, the second buffer structure 122 includes a first elastic plate 141, a second elastic plate 142 and a gusset plate 15; the fixed end of the first elastic plate 141 is fixedly connected to one side of the buffer mounting seat 11, the fixed end of the second elastic plate 142 is fixedly connected to the other side of the buffer mounting seat 11, and the gusset plate 15 is transversely connected between the first elastic plate 141 and the second elastic plate 142; the first buffer structure 121 is fixedly connected to the free end of the first elastic plate 141 and the free end of the second elastic plate 142, respectively, thereby increasing the joint action ability of the second buffer structure 122;

[0028] Among them, the rigidity of the first elastic plate 141 is smaller than the rigidity of the second elastic plate 142, that is, the deformation degree of the first elastic plate 141 is greater than the deformation degree of the second elastic plate 142. In this way, when encountering a large terrain fluctuation, the deformation degree of the first elastic plate 141 is large, which can better absorb the energy generated by the vibration, and the deformation degree of the second elastic plate 142 is small, which can better ensure the structural stability of the buffer shock absorbing device and the equipment using the buffer shock absorbing device; in order to make the rigidity of the first elastic plate 141 smaller than the rigidity of the second elastic plate 142, in some embodiments, the width of the first elastic plate 141 is smaller than the width of the second elastic plate 142; in other embodiments, the curvature of the first elastic plate 141 is greater than the curvature of the second elastic plate 142;

[0029] The distance between the fixing plate 15 and both ends of the first elastic plate 141 is equal to the distance between both ends of the second elastic plate 142. The second buffer structure formed by the first elastic plate 141, the second elastic plate 142 and the fixing plate 15 is A-shaped, so that the second buffer structure has higher stability.

[0030] See also Figure 1 In some embodiments, the free end of the second buffer structure 122 is tilted upward, so that the second buffer structure has a larger working space when performing shock-absorbing and buffering functions, and can better eliminate the remaining force after the first buffer structure acts.

[0031] See also Figure 1In order to reduce the influence of track inclination on the smoothness of the drilling vehicle's movement, in some embodiments, the connecting bottom plate 131 includes a first connecting bottom plate 1311 and a second connecting bottom plate 1312, the moving part 132 includes a first moving part 1321 and a second moving part 1322, and the first buffer structure 121 includes a first buffer spring 1211 and a second buffer spring 1212; the bottom end of the first buffer spring 1211 is fixedly connected to the free end of the first elastic plate 141, the first connecting bottom plate 1311 is fixedly connected to the top of the first buffer spring 1211, and the first moving part 1321 is movably connected to the connecting bottom plate 131; the bottom end of the second buffer spring 1212 is fixedly connected to the free end of the second elastic plate 142, the second connecting bottom plate 1312 is fixedly connected to the top of the second buffer spring 1212, and the second moving part 1322 is movably connected to the connecting bottom plate 141;

[0032] Among them, the length of the second buffer spring 1212 is greater than the length of the first buffer spring 1211, that is, the deformation degree of the second buffer spring 1212 is greater than the deformation degree of the first buffer spring 1211. In this way, when the buffer shock absorbing device is used, the second buffer spring 1212 is in a pre-tightened state in advance. When encountering a deep pit or an area with a large degree of unevenness, the deformation degree of the first buffer spring 1211 is greater than the deformation degree of the second buffer spring 1212 in the pre-tightened state, which can immediately absorb the energy caused by the impact; in other embodiments, the elastic modulus of the first buffer spring 1211 is smaller than the elastic modulus of the second buffer spring 1212. In this way, the deformation degree of the first buffer spring 1211 is greater than the deformation degree of the second buffer spring 1212, which can reduce the impact force on the buffer shock absorbing device; so that the buffer springs arranged front and rear can both perform shock absorption and absorb various impacts caused by uneven sinking of the top plate and tilting of the track; and compared with the buffer springs arranged on the connecting bottom plate A single buffer spring is arranged, and the technical solution provided by the utility model can increase the supporting points of the buffer shock absorbing device. On the one hand, the buffer shock absorbing device can respond to more top plate sinking situations, so that the operation of the equipment installed with the buffer shock absorbing device is smoother, and on the other hand, the service life of the buffer shock absorbing device can be increased; in some embodiments, the moving component can be arranged at the top end of the first buffer spring 1211 and the second buffer spring 1212, that is, the first buffer spring 1211 and the second buffer spring 1212 are arranged in an eight-shaped or a herringbone shape, so that the load borne by the first buffer spring 1211 and the second buffer spring 1212 can be less than the load borne when vertically connected, reducing the deformation of the first buffer spring 1211 and the second buffer spring 1212, making the force of the first buffer spring 1211 and the second buffer spring 1212 more stable, and improving the buffering effect, so as to better ensure the structural stability of the buffer shock absorbing device and the equipment using the buffer shock absorbing device.
