Description

Technical Field

[0001] The utility model relates to the technical field of mine transportation equipment, in particular to a coal mine slurry material transport vehicle. Background Art

[0002] Slurry materials are required for both reinforcing mine tunnels and constructing sealing walls. When reinforcing mine tunnels, the slurry materials can penetrate into the inner part of the mine wall, thereby reinforcing the mine tunnel. When constructing a sealing wall, the slurry materials can block the gaps to ensure the sealing performance of the sealing wall. Most slurry materials are transported to the construction site by a transport vehicle equipped with a slurry discharge pipe. During the transportation process of the transport vehicle, the slurry discharge pipe is blocked by a matching plug to maintain the stable transportation of the slurry materials. After the transport vehicle arrives at the destination, the operator needs to remove the plug from the slurry discharge pipe, and then quickly discharge the slurry materials through the slurry discharge pipe. Subsequently, the discharged slurry materials can be used for reinforcing the mine tunnel and constructing the sealing wall.

[0003] Most of the ways to block the slurry discharge pipe with a plug are of a threaded connection structure. Therefore, when the operator removes the plug to discharge the slurry materials from the slurry discharge pipe, the pressure of the slurry materials inside the transport vehicle will cause the slurry materials to spray out quickly from the slurry discharge pipe, and thus it is very likely to splash and impact the hands that the operator cannot dodge in time. When the operator's hands are impacted by the slurry materials, the sharp sand and gravel in the slurry materials will cause harm to the operator's hands. At the same time, the chemical substances contained in the slurry materials will also cause pollution or corrosive damage to the operator's hands. And although the plug with a threaded structure can block the slurry discharge pipe relatively stably, when removing the plug, the operator needs to use tools such as a wrench to overcome the frictional force caused by the pressure of the slurry materials on the threaded structure, and then complete the removal work of the plug. This brings certain obstacles to the operator to quickly and safely discharge the slurry materials from the transport vehicle. Content of the Utility Model

[0004] The utility model aims to provide a coal mine slurry material transport vehicle to assist in quickly and safely removing the plug, thereby improving the safety and efficiency of discharging the slurry materials from the transport vehicle.

[0005] To solve the above technical problems, the specific solution adopted by the utility model is as follows: a coal mine slurry material transport vehicle, including a transport vehicle body, a diversion pipe protruding outside the transport vehicle body, and a plug arranged on the diversion pipe. The plug is hinged to the protruding end of the diversion pipe;

[0006] A control rope is fixedly connected to the plug, and one end of the control rope passes through the transport vehicle body and is connected with a control rope assembly. The control rope assembly is used to control the relaxation or tension of the control rope, and thus control the opening and closing of the plug.

[0007] As a further optimization of a coal mine slurry material transport vehicle of the present utility model, the plug includes a sealing plate disposed at the outer end of the diversion pipe. A sealing ring is fixedly provided on the side of the sealing plate facing the diversion pipe. The sealing ring is in clearance fit with the inner wall of the diversion pipe. The sealing plate is hinged to the protruding end of the diversion pipe through a hinge seat.

[0008] As a further optimization of a coal mine slurry material transport vehicle of the present utility model, the sealing ring is made of elastic rubber material.

[0009] As a further optimization of a coal mine slurry material transport vehicle of the present utility model, the control rope assembly is disposed on the outer side surface of the transport vehicle body facing away from the diversion pipe.

[0010] As a further optimization of a coal mine slurry material transport vehicle of the present utility model, the control rope assembly includes a hanging rope ring fixedly connected to the control rope. The hanging rope ring is sleeved on a C-shaped hanging rope frame. The hanging rope frame is vertically disposed on the outer side surface of the transport vehicle body facing away from the diversion pipe.

[0011] As a further optimization of a coal mine slurry material transport vehicle of the present utility model, a blocking plate for blocking the C-shaped notch is clamped on the outer side surface of the hanging rope frame, and the upper side wall of the hanging rope frame is inclined upward.

[0012] As a further optimization of a coal mine slurry material transport vehicle of the present utility model, the control rope assembly includes a positioning seat fixedly provided on the transport vehicle body. A threaded rod is threadedly connected to the positioning seat. One end of the threaded rod is rotatably connected to the control rope, and the other end of the threaded rod is fixedly connected to a rotating handle.

[0013] As a further optimization of a coal mine slurry material transport vehicle of the present utility model, two guide wheels for guiding the control rope are fixedly connected to the inner wall of the transport vehicle body.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In the present utility model, one end of the control rope is fixedly connected to the plug, and then the control rope assembly connected to the other end of the control rope is used to control the tension or relaxation of the control rope, thereby controlling the opening and closing of the plug. When the control rope is tightened, the plug will be pulled to rotate under the support of the protruding end of the slurry discharge pipe, and then the plug will block the slurry discharge pipe, that is, the slurry material will be confined to the transport vehicle body to transport the slurry material. When the control rope is relaxed, the slurry material in the transport vehicle body will flush open the plug, and then the slurry material can be discharged through the slurry discharge pipe. The cooperation of the control rope assembly and the control rope can control the opening and closing of the plug, thereby reducing the probability of the slurry material impacting on the hands of personnel, and at the same time avoiding the process of manually searching for a wrench for control, thus improving the safety and efficiency of discharging the slurry material from the transport vehicle.

[0016] As a further optimization of the present utility model, the present utility model facilitates the operator to control the tension of the control rope by arranging a positioning seat and a threaded rod, that is, it facilitates the operator to control the plug to flip on the slurry discharge pipe by using the hinge seat, and further controls the size of the opening of the discharge port of the slurry discharge pipe, so as to facilitate the operator to control the discharge speed of the slurry material.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Embodiment 1

[0023] A coal mine slurry material transport vehicle of the present utility model, which is the same as the prior art, includes a transport vehicle body 3. The transport vehicle body 3 can transport coal mine slurry materials, and a protruding slurry discharge pipe 2 is provided on the outer side surface of the transport vehicle body 3. The slurry discharge pipe 2 can assist personnel in discharging the coal mine slurry materials. A plug 1 is provided at the protruding end of the slurry discharge pipe 2. The plug 1 can ensure the restraint of the slurry materials during the transportation of the coal mine slurry materials by the transport vehicle body 3, and thus maintain a stable slurry material transportation function.

[0024] Different from the prior art that the plug 1 is threadedly connected to the slurry discharge pipe 2, the plug 1 is hinged to the protruding end of the slurry discharge pipe 2 through a hinge seat 103, so as to maintain the connection stability between the plug 1 and the slurry discharge pipe 2 during the opening and closing process of the plug 1. A control rope 4 is fixedly connected to the plug 1, and the other end of the control rope 4 is connected to a control rope assembly 5. Personnel can use the control rope assembly 5 and the control rope 4 to control the opening and closing of the plug 1, that is, it is convenient for personnel to control the safety, stability and convenience of the transportation and discharge of coal mine slurry materials by the transport vehicle body 3.

[0025] One end of the control rope 4 passes through two guide wheels 6, and the transport vehicle body 3 is connected with a control rope assembly 5. The arrangement of the two guide wheels 6 can reduce the wear of the control rope 4 and at the same time reduce the force used by personnel to manipulate the control rope 4. One end of the control rope 4 is arranged at the end of the plug 1 and is distributed at the position of the plug 4 away from the hinge seat 103, so as to facilitate personnel to pull the plug 1 back to its position to block the slurry discharge pipe 2 with less effort.

[0026] The plug 1 includes a sealing plate 101 arranged at the outer end of the slurry discharge pipe 2. A sealing ring 102 is fixedly arranged on the side of the sealing plate 101 facing the slurry discharge pipe 2. The sealing ring 102 is made of elastic rubber material. When the sealing ring 102 is in clearance fit with the inner wall of the slurry discharge pipe 2, it can increase the stability of the sealing plate 101 in blocking the slurry discharge pipe 2, thereby improving the stability of the transport vehicle body 3 in transporting coal mine slurry materials.

[0027] The control rope assembly 5 can relax or tension the control rope 4. When the control rope 4 is tensioned, the plug 1 will be tightened by the control rope 4, and then cooperate with the hinge of the plug 1 and the slurry discharge pipe 2 to overcome the pressure of the coal mine slurry materials in the transport vehicle body 3, that is, block the slurry discharge pipe 2 to facilitate personnel to transport coal mine slurry materials by using the transport vehicle body 3. When the control rope 4 is relaxed, the plug 1 will be pushed open by the pressure of the coal mine slurry materials and flip on the slurry discharge pipe 2, and then the coal mine slurry materials can be discharged by using the slurry discharge pipe 2. After all the slurry materials are discharged, the control rope 4 can also be tightened by using the control rope assembly 5 to make the plug 1 reset, so as to facilitate personnel to carry out the next transportation of coal mine slurry materials.

[0028] The control rope assembly 5 is arranged on the outer side surface of the transport vehicle body 3 facing away from the slurry discharge pipe 2, so as to facilitate personnel to use the control rope assembly 5 to cooperate with the control rope 4 to control the opening and closing of the plug 1, that is, control the penetration and blocking of the slurry discharge pipe 2, so as to facilitate personnel to transport and discharge coal mine slurry materials by using the transport vehicle body 3. The control rope assembly 5 is arranged at the position of the transport vehicle body 3 facing away from the slurry discharge pipe 2, so as to reduce the probability that the personnel's body is covered by the coal mine slurry materials flushed out, that is, reduce the probability of personnel being injured by the coal mine slurry materials, thereby maintaining the safety of personnel in discharging coal mine slurry materials.

[0029] The above is the basic embodiment of the present invention, and further improvements, optimizations and limitations can be made on this basis to obtain the following embodiments:

[0030] Embodiment 2

[0031] This embodiment further elaborates on the structure of the control rope assembly 5 on the basis of Embodiment 1. Its main structure is the same as that of Embodiment 1, and the specific elaboration is as follows: As Figure 1 and Figure 2As shown, the control rope assembly 5 includes a hanging rope ring 501 fixedly connected to the end of the control rope 4, and the hanging rope ring 501 is connected to a hanging rope frame 502, which is C-shaped and vertically arranged on the outer surface of the side of the transport vehicle body 3 away from the slurry discharge pipe 2. The hanging rope frame 502 can facilitate personnel to keep the control rope 4 in a stable tensioned state, thereby maintaining the closed function of the transport vehicle body 3, that is, maintaining the stability of the transport vehicle body 3 in transporting coal mine slurry materials.

[0032] The rope rack 502 is clamped with a blocking plate 503 that blocks the C-shaped notch, thereby further stabilizing the relative position of the rope ring 501, that is, assisting personnel to stabilize the tension state of the control rope 4. The upper side wall of the rope rack 502 is inclined upward, so that when the personnel loosens the control rope 4, they can easily remove the rope ring 501 from the rope rack 502, thereby facilitating the personnel to control the loosening or tensioning state of the control rope 4.

[0033] Example 3

[0034] This embodiment further describes the structure of the rope control assembly 5 on the basis of the embodiment 1. Its main structure is the same as that of the embodiment 1, and is described in detail as follows: Figure 3 and Figure 4 As shown, the rope control assembly 5 includes a positioning seat 504, which is fixed on the upper side of the side wall of the transport vehicle body 3 away from the slurry discharge pipe 2. The positioning seat 504 is threadedly connected with a threaded rod 505, and the positioning seat 504 can maintain the relative position of the threaded rod 505.

[0035] The rotation of the threaded rod 505 can cooperate with the positioning seat 504 to change the screwing amount of the threaded rod 505, so that the personnel can control the opening and closing of the plug 1 by operating the control rope 4. One end of the threaded rod 505 is rotatably connected to the end of the control rope 4, thereby preventing the control rope 4 from being damaged by the rotation of the threaded rod 505, and also reducing the influence of the torsion force generated by the self-rotation of the control rope 4 on the tightening of the plug 1.

[0036] The other end of the threaded rod 505 is fixedly connected to a rotating handle 506, which is a long handle rod, so that personnel can control the rotation of the threaded rod 505 with less effort. The rotation of the threaded rod 505 can cooperate with the positioning seat 504 to change the amount by which it is screwed into the positioning seat 504, so that personnel can control the relaxation or tightening of the control rope 4, thereby facilitating personnel to control the opening and closing of the plug 1.

[0037] The threads of the threaded rod 505 cooperate with the positioning seat 504 to more accurately control the tension of the control rope 4, that is, to control the amount of the plug 1 covering the protruding end of the slurry discharge pipe 2, thereby controlling the discharge speed of the coal mine slurry material.
