Manual opening device for mine car body

Abstract

The car body comprises a chassis and a compartment hinged to the position, located at the rear end, of the chassis, a compartment door capable of being opened and closed relative to the compartment is hinged to the top of the rear end of the compartment, the manual opening device is arranged on the compartment, and one end of the manual opening device extends to a driving position. And the other end extends to the compartment door and can be propped against or separated from the outer wall of the compartment door. The compartment door is limited by abutting the manual opening device against the compartment door, and the problem that raw ores are scattered due to the fact that the compartment door is automatically opened and the raw ores are pushed to be opened in the transportation process is solved. When the raw ore is dumped, one end of the manual opening device extends to a driving position, so that a driver can drive the manual opening device to enable the tail end of the manual opening device to be separated from the compartment door to realize dumping, and the convenience and safety of opening and closing operation of the compartment door are improved. Meanwhile, the manual opening device is simple in structure and can be arranged and used on similar dragging type locomotive bodies at low cost.

Description

Technical Field

[0001] This application relates to the field of raw ore transportation technology, and in particular to a manual opening device for a mining vehicle body. Background Technology

[0002] Gold mines are ores containing a certain amount of gold. These ores are typically processed through mining, crushing, and beneficiation to extract the gold. For surface or shallow gold deposits, open-pit mining is commonly used. This method has advantages such as large-scale mining, high efficiency, and low cost, but it can also damage the surface environment. For deep or complex geological conditions, underground mining is a more suitable option. Underground mining requires the construction of shafts and mining facilities, and strict control of influencing factors such as ground pressure and groundwater is necessary during the mining process.

[0003] After mining, ore beneficiation and smelting will be carried out, and the raw ore will need to be transported. Currently, depending on the specific conditions of the mine and the mining method, the transportation methods for raw ore may include conveyor belt transportation, narrow-gauge railway transportation, automobile transportation, and aerial cableway transportation. The transportation of gold mines needs to overcome the limitations of natural conditions such as terrain and climate.

[0004] Currently, road transport offers greater flexibility compared to other modes of transportation, and trucks are typically used. However, in mining areas with complex geographical environments and limited road conditions, large transport vehicles cannot pass smoothly. Therefore, smaller ore trucks are generally used to transport raw ore in mining areas. (See attached instruction manual) Figure 1 As shown, the ore truck body includes a chassis and a cargo box articulated at the rear end of the chassis. A cargo door, which can be opened and closed relative to the cargo box, is articulated at the bottom of the rear end of the cargo box. The opening method of the cargo door is as follows: Figure 2 As shown, the cargo door is first opened downwards, and then driven by the drive cylinder in the chassis, the vehicle body tilts at the rear hinge, allowing the ore to be dumped. However, in this method, some of the ore inside the cargo box will spill out when the cargo door is opened, potentially causing impact contact to the operator and spilling ore onto them, posing a safety hazard. To address this issue, the upper part of the cargo door of the ore truck is now hinged to the cargo box, as shown... Figure 3-4 As shown, during the opening process, driven by the cylinder, the raw materials are gradually poured out, automatically pushing open the door to allow the ore to be dumped, thus eliminating the safety hazards associated with manually opening the door. Furthermore, as the vehicle moves after loading the ore, the ore inside the compartment will automatically push the door open, spilling some of it, such as... Figure 5 The state shown results in the waste of raw ore and environmental pollution. Summary of the Invention

[0005] To address the aforementioned problems, this application aims to provide a manual opening device for a mining truck body, which can restrict the opening of the truck door, prevent the door from opening on its own during transportation, and allow operation from the driver's seat when dumping raw ore, thereby improving the ease of operation of the manual opening device.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a manual opening device for a mining car body, the car body including a chassis and a car body hinged at the rear end of the chassis, a door hinged at the top of the rear end of the car body that can be opened and closed relative to the car body, characterized in that: the manual opening device is disposed on the car body, and one end extends to the driver's seat, and the other end extends to the door and can abut or detach from the outer wall of the door.

[0007] Preferably, the manual opening device includes clamping blocks arranged at horizontal intervals on the side wall of the carriage, with a rotatable opening and closing rod passing through the clamping blocks. The front end of the opening and closing rod near the driver's seat is provided with a drive handle, while the rear end is provided with a locking rod that can abut against or disengage from the outer wall of the carriage door.

[0008] Preferably, the locking rod is axially movable and passes through the clamping block, and a protective block that can contact the clamping block is provided on the opening and closing rod between the drive handle and the clamping block.

[0009] Preferably, the opening and closing rod and the inner wall of each clamping block are both tapered and interlocking structures.

[0010] The beneficial effects of this application are: by using a manual opening device to restrain the tractor door, the problem of the door opening on its own during transportation and the ore scattering due to the ore being pushed open is overcome. When dumping the ore, one end of the manual opening device extends to the driver's seat, allowing the driver to disengage the rear end from the door by driving the device, thus improving the convenience and safety of opening and closing the door. Furthermore, this manual opening device has a simple structure and can be installed and used at low cost on similar tractor bodies. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] See attached document Figures 1-11 The illustration shows a manual opening device for a mining truck body. The truck body includes a chassis 1 and a cargo box 2 hinged to the rear end of the chassis 1. A door 3, which can be opened and closed relative to the cargo box 2, is hinged to the top rear end of the cargo box 2. Currently, when dumping raw ore, the cargo box 2 is tilted by a drive cylinder, which then automatically pushes open the door 3 to dump the raw ore. To address the problem of raw ore spillage and waste caused by the door 3 opening automatically during transportation, this application provides a manual opening device for the mining truck body, such as... Figure 6As shown, the manual opening device is installed on the carriage 2, with one end extending to the driver's seat and the other end extending to the door 3, which can abut or detach from the outer wall of the door 3. When the carriage is loaded with raw ore, the abutment of the door 3 by the manual opening device restricts the door 3, overcoming the problem of the door 3 opening on its own during transportation and the raw ore scattering due to pushing open. When dumping the raw ore, one end of the manual opening device extends to the driver's seat, allowing the driver to disengage the rear end from the door 3 by driving the manual opening device, thus releasing the restriction on the door 3. Then, the drive cylinder drives the carriage 2 to tilt, completing the dumping of the raw ore. After dumping, the lower carriage 2 is in a horizontal state, and the manual opening device is driven again from the driver's seat to abut and restrict the door 3 again, thus allowing for the next loading and transportation of raw ore.

[0025] Specifically, such as Figure 6-8 As shown, the manual opening device includes clamping blocks 4 horizontally spaced on the side wall of the carriage 2, preferably welded to the side wall of the carriage 2. A rotatable opening and closing rod 5 is threaded through the clamping blocks 4. The front end of the opening and closing rod 5 near the driver's seat is provided with a drive handle 51, and the rear end is provided with a locking rod 52 that can abut or disengage from the outer wall of the carriage door 3. The drive handle 51 is formed by bending the end of the opening and closing rod 5 by 90°, and similarly, the locking rod 52 is formed by bending the rear end of the opening and closing rod 5 by 90°. The driver can rotate the locking lever 52 by driving the drive handle 51 from the driver's seat. After the locking lever 52 rotates to a horizontal position, it abuts against the outer wall of the cargo door 3, thus limiting the automatic opening of the cargo door 3 and the pushing of the ore, effectively preventing spillage of the ore during transportation. When dumping the ore, the driver rotates the opening and closing lever 51 from the driver's seat, and at the same time, the locking lever 52 rotates to the outside of the cargo door 3, disengaging from the cargo door 3. Thus, when the cargo box 2 is driven by the drive cylinder, the cargo door 3 can open automatically, allowing the ore to be dumped. After dumping is completed, the driver rotates the drive handle 51 again, causing the locking lever 52 to be in a horizontal position and abut against the outer wall of the cargo door 3, thus limiting the opening of the cargo door 3.

[0026] After the raw ore is loaded into the carriage 2, the contact between the raw ore and the inner wall of the carriage door 3 will push the carriage door 3 outward, resulting in an increase in the force between the carriage door 3 and the locking rod, and an increase in the rotational resistance of the drive handle 51. Therefore, to solve this problem, such as... Figure 10 As shown, the locking rod 52 is axially movable and passes through the clamping block 4. During subsequent tilting, the opening and closing rod 5 is pushed backward during the rotation of the drive handle 51, causing the locking rod 52 to disengage from the outer wall of the door 3 at a certain distance, thus allowing the locking rod 52 to rotate smoothly and the door 3 to open. To prevent the opening and closing rod 5 from moving backward under the drive of the door 3 during transportation, which could result in the door 3 not locking properly, as follows... Figure 9 As shown, a pin 8 is preferably provided on the clamping block 4 near the driver's seat. Inserting the pin into the opening / closing lever 5 limits the movement of the lever 5, preventing the door 3 from being unable to lock properly due to the door 3's drive on the locking lever 52 during transport, and also limiting the rotation of the opening / closing lever 5 to prevent the locking lever 52 from disengaging from the door 3. When dumping the raw ore later, the pin is pulled up and removed (or pried open with a small wrench), which drives the opening / closing lever 5 to move backward and, along with the rotation of the drive handle 51, opens the door 3 via the locking lever 52.

[0027] To avoid excessive axial movement and impact of the opening / closing lever 5 within the clamping block 4 due to excessive pushing of the raw ore against the door 3, such as... Figure 9 As shown, a protective block 6 is provided on the opening / closing rod 5 between the drive handle 51 and the clamping block 4, which is in contact with the clamping block 4. After the latch is removed, under the pushing action of the ore and before the locking rod 52 has fully rotated and disengaged from the door 3, the axial drive of the opening / closing rod 5 is limited by the contact between the protective block 6 and the foremost clamping block 4, thus avoiding the impact problem caused by large axial movement of the opening / closing rod 5.

[0028] In order to facilitate the smooth rearward movement of the opening / closing lever 5 so that the locking lever 52 can smoothly disengage from the opened door 3, such as... Figure 11 As shown, the opening / closing rod 5 and the inner wall of each clamping block 4 are both tapered and interlocking structures. This tapered interlocking structure allows the gap between the opening / closing rod 5 and the clamping block 4 to gradually increase as the rod moves backward, thereby reducing the sliding friction between the rod 5 and the inner hole of the clamping block 4. This enables the opening / closing rod 5 to move smoothly backward, disengaging the locking rod 52 from the door 3 and facilitating the smooth dumping of the ore.

[0029] The principle of this application is as follows: A clamping block 4 is welded onto the side wall of the cargo compartment of the ore truck, and an opening / closing rod 5 with a drive handle 51 and a locking rod 52 is inserted inside it. When loading raw ore, the rotation of the drive handle 51 causes the locking rod 52 to abut against the outer wall of the cargo door 3, and the position of the opening / closing rod 5 is locked by the insertion of a pin in the clamping block 4, thus allowing the loading of raw ore. When dumping raw ore later, the pin is pulled out, and the opening / closing rod 5 is driven backward by rotating the drive handle 51, so that the locking rod 52 can be smoothly disengaged from the cargo door 3. Then, the raw ore can be dumped by the drive cylinder. After dumping, the cargo compartment returns to a horizontal state, and the pin is inserted into the clamping block 4 and the opening / closing rod 5 to lock the cargo door 3, so that the next raw ore loading operation can be carried out.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
