Description

Technical Field

[0001] This utility model relates to the field of coal mining equipment transportation technology, and in particular to a frame-type vehicle blocking device for mining vehicles. Background Technology

[0002] Currently, trackless wheeled vehicles are widely used for transporting materials and equipment in coal mine production and fully mechanized mining face installation and withdrawal. Vehicle stoppers are particularly important during transportation. The currently used stoppers are wedge-shaped (made of wood or rubber); the driver needs to get out of the vehicle to operate them. When stopping on a sloped driving route, the driver faces a high risk in placing the stopper, and the stopper may not be in place in time when the vehicle malfunctions, which may cause certain risks.

[0003] Currently, wheel chocks need to be transported with the vehicle, posing a risk of loss. When parking, drivers must manually install the wheel chocks under the tires, which can lead to improper operation, especially when parking on slopes. Installing and removing the wheel chocks also poses a safety hazard to the driver. Furthermore, if the vehicle breaks down on a slope, the driver cannot get out of the vehicle in time to install the wheel chock, creating a driving safety hazard. Utility Model Content

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] Before providing a further detailed description of the embodiments of this utility model, the directional terms used in the embodiments of this utility model, such as "upper part", "lower part" and "side part", do not have the meaning of limiting the scope of protection of this utility model.

[0038] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0039] One embodiment of this utility model provides a frame-type vehicle blocking device 100 for mining vehicles, the frame-type vehicle blocking device 100 comprising:

[0040] The power unit is located on mining vehicle 200;

[0041] The control component 110 is connected to the power component and is located between the two tires 210 on the same side of the mining vehicle 200.

[0042] The actuator 1120 is connected to the control assembly 110, and when the vehicle is stopped, at least part of the actuator 120 abuts against the tire 210 of the mining vehicle 200;

[0043] The power component provides power to the control component 110, and the control component 110 controls the movement of the execution component 120.

[0044] The frame-type vehicle blocking device 100 includes a power component, a control component 110, and an execution component 120 connected in sequence. The power component directly uses the on-board air tank of the mining vehicle 200. The pressure of the on-board air tank provides power to the control component 110. The operation of the control component 110 drives the execution component 120 to move, thereby enabling the execution component 120 to block the movement of the tire 210 or move away from the tire 210. The frame-type vehicle blocking device 100 is directly fixed between the gaps of the two tires 210 on the same side, avoiding the loss caused by placing the blocking blocks directly on the vehicle during transportation. The driver does not need to get off the vehicle to operate it; the vehicle blocking operation can be completed directly on the vehicle, improving the convenience of the vehicle blocking operation. When the mining vehicle 200 stops on a slope, the two tires 210 on the same side can be engaged without the staff getting off the vehicle, improving the safety of vehicle blocking and the safety of the staff. The simultaneous engagement of the two tires 210 improves the reliability of the vehicle blocking operation.

[0045] Figure 3 This is a schematic diagram of the use of a frame-type vehicle blocking device according to an embodiment of the present invention.

[0046] In one feasible implementation, such as Figure 3 As shown, the control component 110 includes: an auxiliary pump 111, a reversing valve 112 and a hydraulic cylinder 113. The reversing valve 112 is connected to the auxiliary pump 111 and the hydraulic cylinder 113 respectively. The reversing valve 112 is driven to reverse through the power component. The extension rod of the hydraulic cylinder 113 is connected to the execution component 120.

[0047] The frame-type vehicle blocking device 100 also includes an oil tank, an auxiliary pump 111 and a reversing valve 112, which are respectively connected to the oil tank.

[0048] When the mine vehicle 200 needs to be stopped, the handbrake of the mine vehicle 200 is closed, and the reversing valve 112 is in the first working position. At this time, the auxiliary pump 111 draws oil from the oil tank, and after passing through the reversing valve 112, it enters the rodless chamber of the hydraulic cylinder 113. As the oil in the rodless chamber increases, it pushes the extension rod of the hydraulic cylinder 113 to extend, thereby causing the actuator 120 to extend. The actuator 120 then abuts against the tire 210, thus stopping the vehicle. When the mine vehicle 200 needs to move, the handbrake of the mine vehicle 200 is opened, and the reversing valve 112 is in the second working position. At this time, the auxiliary pump 111 draws oil from the oil tank, and after passing through the reversing valve 112, it enters the rod chamber of the hydraulic cylinder 113. As the oil in the rod chamber increases, it pushes the extension rod of the hydraulic cylinder 113 to retract, thereby causing the actuator 120 to retract as well. The actuator 120 moves away from the tire 210, and the mine vehicle 200 moves normally.

[0049] It should be noted that the control switch for the auxiliary pump 111 can be located inside the vehicle or controlled remotely, with the remote control kept by the driver. The power source for pushing the reversing valve 112 to change its operating position is the pressure of the on-board air tank. The on-board air tank is a device in the automotive braking system used to store compressed air or vacuum booster, and its main function is to improve braking safety performance, which is related to the operating position of the handbrake. This is conventional technology in this field and will not be elaborated further.

[0050] In one feasible implementation, the control valve 112 is a two-position four-way valve. When the frame-type vehicle blocking device 100 is in working state, the first oil inlet of the two-position four-way valve is connected to the auxiliary pump 111, the first oil outlet of the two-position four-way valve is connected to the rodless chamber of the hydraulic cylinder 113, the rod chamber of the hydraulic cylinder 113 is connected to the second oil inlet of the two-position four-way valve, and the second oil outlet of the two-position four-way valve is connected to the oil tank.

[0051] When the frame-type vehicle blocking device 100 is not in operation, the first oil inlet of the two-position four-way valve is connected to the auxiliary pump 111, the first oil outlet of the two-position four-way valve is connected to the rod chamber of the hydraulic cylinder 113, the rodless chamber of the hydraulic cylinder 113 is connected to the second oil inlet of the two-position four-way valve, and the second oil outlet of the two-position four-way valve is connected to the oil tank.

[0052] Specifically, when the frame-type vehicle blocking device 100 is in working state, that is, when the actuator 120 extends and abuts against the tire 210, the two-position four-way valve is in the first working position. At this time, the auxiliary pump 111 sends oil through the two-position four-way valve into the rodless chamber of the hydraulic cylinder 113, pushing the rod chamber outward, which in turn drives the actuator 120 outward until the actuator 120 abuts against the tire 210, thus realizing the vehicle blocking operation. At this time, the oil in the rod chamber of the hydraulic cylinder 113 returns to the oil tank through the two-position four-way valve. When the frame-type vehicle blocking device 100 is not in operation, that is, when the actuator 120 is away from the tire 210, the two-position four-way valve is in the second working position. At this time, the auxiliary pump 111 sends oil through the two-position four-way valve into the cylinder chamber of the hydraulic cylinder 113, pushing the telescopic rod of the hydraulic cylinder 113 to move and retract to the rodless chamber, thereby driving the actuator 120 away from the tire 210, so as to realize the normal driving of the mining vehicle 200. At this time, the oil in the rodless chamber of the hydraulic cylinder 113 returns to the oil tank through the two-position four-way valve.

[0053] It should be noted that the extension and retraction of the telescopic rod of the hydraulic cylinder 113 is achieved by switching the two-position four-way valve, realizing the convenience and speed of both vehicle blocking and non-vehicle blocking operations; the two-position four-way valve has better sealing performance, avoiding oil leakage, which on the one hand improves the reliability of the frame-type vehicle blocking device 100, and on the other hand reduces the loss of oil in the oil tank, thus improving economy.

[0054] In one feasible implementation, such as Figure 3 As shown, the control component 110 also includes:

[0055] A one-way valve 114 is disposed between the auxiliary pump 111 and the reversing valve 112;

[0056] The accumulator 115 is located between the check valve 114 and the directional valve 112.

[0057] The one-way valve 114 prevents oil from entering the rodless or rod chamber, ensuring the oil returns along its original path and guaranteeing reliable unidirectional oil flow. This improves the stability and reliability of the hydraulic cylinder 113. The accumulator 115 stores energy, releasing it during peak demand from the control component 110. This reduces frequent start-stop cycles of the auxiliary pump 111, lowers energy consumption, and extends its lifespan. When the auxiliary pump 111 or actuator 120 stops suddenly, the accumulator 115 buffers peak pressure, protecting the connecting pipes and auxiliary pump 111 from significant impact damage. In case of auxiliary pump 111 failure or power failure, it provides temporary power to ensure a stable stop for actuator 120, improving the safety of the frame-type vehicle braking device 100. The accumulator 115 also reduces noise and vibration, improves the stability of the frame-type vehicle braking device 100, compensates for minor oil leaks, and maintains constant pressure in the control component 110.

[0058] It should be noted that, in this embodiment, the hydraulic cylinder 113 is a two-stage telescopic cylinder with a stroke of 600mm; the reversing valve 112 is a pneumatically controlled hydraulic two-position four-way reversing valve with an orifice diameter of 13mm; there are two 2.5L accumulators 115 and one 13mm diameter check valve 114. The rest are connected via air and hydraulic pipes as needed. After the control assembly 110 is connected, the driver in the cab operates the control switch and handbrake, using the air pressure in the air tank to push the cylinder, controlling the two-position four-way valve of the control assembly 110 to operate, thereby realizing the raising and lowering of the arc-shaped connecting rod 121 and the vehicle stop block 122 in the actuator 120.

[0059] In one feasible implementation, the power unit is an on-board gas tank.

[0060] The reversing power of the reversing valve 112 comes from the vehicle-mounted air tank, which is related to the working position of the handbrake. When the handbrake is closed, the frame-type vehicle blocking device 100 starts to block the vehicle. When the handbrake is pulled open, the mining vehicle 200 can drive normally. At this time, the frame-type vehicle blocking device 100 is in a non-working state, and the mining vehicle 200 can drive normally.

[0061] It should be noted that the power source for the auxiliary pump 111 can be the electricity provided by the engine of the mining vehicle 200, which is common knowledge in this field and will not be elaborated further.

[0062] Figure 1 This is a schematic diagram of a frame-type vehicle blocking device according to an embodiment of the present invention; Figure 2 This is another schematic diagram of a frame-type vehicle blocking device according to an embodiment of the present invention.

[0063] In one feasible implementation, such as Figure 1 and Figure 2As shown, the execution component 120 includes:

[0064] Arc-shaped connecting rod 121, a pair of arc-shaped connecting rods 121 are hinged to the control assembly 110;

[0065] The vehicle blocking block 122 includes a first surface 1221, a second surface 1222 and a third surface 1223 that are connected to each other. The first surface 1221 is disposed facing the tire 210, the second surface 1222 is connected to the end of the arc-shaped connecting rod 121 away from the control component 110, and the third surface 1223 is disposed facing the running surface of the tire 210.

[0066] In this configuration, a pair of arc-shaped connecting rods 121 are hinged to the telescopic rod of the hydraulic cylinder 113, and one end of the arc-shaped connecting rods 121 away from the hydraulic cylinder 113 is fixedly connected to the wheel stop block 122. When the two-position four-way valve is in its first working position, the telescopic rod of the hydraulic cylinder 113 extends, which in turn drives the pair of arc-shaped connecting rods 121 and the wheel stop block 122 to extend, causing the wheel stop block 122 to abut against the tire 210. With a pair of arc-shaped connecting rods 121 and a pair of wheel stop blocks 122, both tires 210 on the same side can be blocked without considering the slope direction, thus improving the reliability and stability of wheel stop.

[0067] It should be noted that the distance between the two ends of the arc-shaped connecting rod 121 can be set and limited by inputting the tire spacing and tire height of the mining vehicle 200 into the three-dimensional software. Since the height and spacing of each mining vehicle 200 are different, this application does not impose any restrictions. As long as the anti-vehicle block 122 moves away from the tire when the arc-shaped connecting rod 121 is retracted, and the anti-vehicle block 122 abuts against the tire 210 after the arc-shaped connecting rod 121 is extended.

[0068] In one feasible implementation, the arc-shaped connecting rod 121 includes a first arc segment 1211, a second arc segment 1212, and a connecting segment 1213 connected in sequence. The first arc segment 1211 is hinged to the control component 110, and the connecting segment 1213 is fixedly connected to the vehicle stop block 122. The center of the first arc segment 1211 and the center of the second arc segment 1212 are set opposite to each other.

[0069] When the frame-type vehicle blocking device 100 is in operation, the center of a pair of first arc segments 1211 is located outside the pair of first arc segments 1211, and the center of a pair of second arc segments 1212 is located inside the pair of second arc segments 1212.

[0070] The first arc segment 1211, at one end away from the second arc segment 1212, is hinged to the telescopic rod of the hydraulic cylinder 113. The connecting segment 1213, at one end away from the second arc segment 1212, is fixedly connected to the vehicle blocking block 122. Because the centers of the first arc segment 1211 and the second arc segment 1212 are positioned opposite each other, and because the first arc segment 1211 is hinged to the telescopic rod, when the pair of arc-shaped connecting rods 121 retract, the push from the through-hole of the mounting frame 130 allows the pair of vehicle blocking blocks 122 to approach and move away from the tire 210, without affecting the normal operation of the mining vehicle 200. At this time, the two first arc segments 1211 form an elliptical annular space. When a vehicle blocking operation is required, the telescopic rod of the hydraulic cylinder 113 extends. At this time, under the push of the passage of the mounting frame 130, the two first arc-shaped segments 1211 move closer to the two tires 210 respectively, thereby driving the second arc-shaped segment 1212 and the blocking block 1213 to move towards the tires until the blocking block 122 abuts against the tires 210, thus realizing the vehicle blocking operation. At this time, the telescopic rod is fully extended and located at the bottom of the mounting frame 130, and the pair of arc-shaped connecting rods 121 are completely located outside the mounting frame 130.

[0071] It should be noted that the first arc segment 1211 and the second arc segment 1212 are connected by an arc segment transition.

[0072] In one feasible implementation, the first surface 1221 of the vehicle blocking block 122 is disposed facing the tire 210 side, and the first surface 1221 is an arc-shaped plate, the curvature of which matches the curvature of the tire 210.

[0073] The side of the vehicle blocking block 122 that abuts against the tire 210 is set as an arc plate, and the arc of the arc plate matches the arc of the tire 210. This can improve the fit between the vehicle blocking block 122 and the tire 210, thereby improving the reliability and stability of the vehicle blocking operation.

[0074] It should be noted that the first arc segment 1211 and the second arc segment 1212 are designed in an arc shape, which facilitates the installation of the first arc segment 1211 of the pair of arc-shaped connecting rods 121 on the mounting frame 130 to extend to both sides, thereby enabling the vehicle blocking block 122 to block the tire 210. Alternatively, by pushing the second arc segment 1212 of the pair of arc-shaped connecting rods 121 to retract inward, the pair of vehicle blocking blocks 122 move closer to each other and away from the tire 210, thus enabling the normal operation of the mining vehicle 200. Specifically, the vehicle blocking block 122 is in the retracted state (e.g., Figure 1As shown), a vehicle-stopping operation is now required. The extension rod of the hydraulic cylinder 113 extends, causing a pair of arc-shaped connecting rods 121 to move downwards. Through the passage, the two first arc-shaped segments 1211 first cross and then extend in opposite directions until they are fully extended from the mounting frame 130, and the vehicle-stopping block 122 abuts against the tire 210. When the mining vehicle 200 needs to move, the hydraulic cylinder 113 retracts, causing the pair of arc-shaped connecting rods 121 to retract into the mounting frame 130. The passage will also touch the first arc-shaped segments 1211, causing the pair of first arc-shaped segments to approach and begin to cross initially. When the passage touches the second arc-shaped segment 1212, it allows the pair of vehicle-stopping blocks 122 to approach each other. At this time, the pair of first arc-shaped segments 1211 form an elliptical shape within the mounting frame 120, as shown... Figure 1 As shown, this facilitates the extension during the next vehicle-stopping operation. By setting the arc-shaped connecting rod 121 to an arc segment, the telescopic distance of the frame-type vehicle-stopping device 100 in the width direction can be reduced, which means that the frame-type vehicle-stopping device 100 can be easily installed in a narrower position between the two tires 210, improving the feasibility of installing the frame-type vehicle-stopping device 100.

[0075] In one feasible implementation, the arc-shaped connecting rod 121 is made of steel plate with a thickness of 12mm to 16mm, the wheel stop block 122 is made of steel plate with a thickness of 10mm to 14mm, and the first surface 1221 of the wheel stop block 122 is an anti-slip steel plate.

[0076] In this embodiment, the arc-shaped connecting rod 121 is made of steel plate with a thickness of 12 mm, a width of 50 mm, and a length of 600 mm. The vehicle blocking block 122 consists of a first surface 1221, a second surface 1222, and a third surface 1223 connected in sequence. When facing the frame-type vehicle blocking device 100, a vehicle blocking block 122 resembling a triangle (with one side being an arc) can be seen, thus achieving the vehicle blocking function. To improve the stability and reliability of the vehicle blocking operation, a connecting plate can be provided on both the side of the vehicle blocking block 122 facing the mining vehicle 200 and the side facing away from the mining vehicle 200. The connecting plates are respectively connected to the sides of the first surface 1221, the second surface 1222, and the third surface 1223. The first surface 1221, the second surface 1222, the third surface 1223, and the two connecting plates form a receiving space. Iron blocks or steel blocks can also be welded into the receiving space to further increase the weight of the vehicle blocking block 122, thereby improving the stability and reliability of the vehicle blocking block 122 in blocking the vehicle. The five sides of the vehicle blocking block 122 are all made of steel plates with a thickness of 10mm. The first side 1221 is an anti-slip steel plate, usually a bean-shaped patterned steel plate, which can increase the friction between the tire 210 and the first side 1221 of the vehicle blocking block 12, thereby improving the reliability and stability of the vehicle blocking operation.

[0077] In one feasible implementation, the frame-type vehicle blocking device 100 further includes a mounting frame 130, and a control component 110 is disposed within the mounting frame 130. When the frame-type vehicle blocking device 100 is not in operation, at least a portion of the execution component 120 is located within the mounting frame 130.

[0078] The mounting frame 130 facilitates the overall installation of the frame-type vehicle blocking device 100 on both sides of the same-side tire 210 of the mining vehicle 200. It also ensures the safety of the hydraulic cylinder 113 in the control component 110, preventing debris from flying onto the hydraulic cylinder 113 and causing damage. A cover plate can be installed on the side of the mounting frame 130 away from the body of the mining vehicle 200 to enclose the hydraulic cylinder 113, improving the safety of the hydraulic cylinder 113's working ring.

[0079] It should be noted that, since the actuator 120 extends or retracts along with the telescopic rod of the hydraulic cylinder 113, the mounting frame 130 has a passage on the ground-facing side to facilitate the extension and retraction of the arc-shaped connecting rod 121 in the actuator 120. Understandably, the mounting frame 130 primarily covers the hydraulic cylinder 113; when the frame-type vehicle-stopping device 100 is in a non-operating state, most of the arc-shaped connecting rod 121 will also retract into the mounting frame 130.

[0080] It is understood that a frame-type vehicle blocking device 100 is provided between the two tires 210 on the same side of the present application, that is, a mining vehicle 200 uses two frame-type vehicle blocking devices 100. This can improve the stability of the vehicle blocking operation and avoid one side slipping when blocking the vehicle on a slope, which would affect the stability and reliability of the vehicle blocking operation.

[0081] Currently used wheel chocks 122 are placed separately, making them prone to loss during transportation. This often results in improper installation of wheel chocks 122 during parking. The frame-type wheel chock device 100 of this application is connected to the body of the mining vehicle 200 and located between the two tires 210 on the same side. It is linked to the parking brake (handbrake), enabling the driver to automatically lower the wheel chock 122 when the driver pulls the handbrake and the arc-shaped connecting rod 121 drives the wheel chock 122 to rise automatically when the driver starts the vehicle and releases the handbrake. This eliminates the problem of improper installation of wheel chocks 122 during parking. Existing wheel chocks 122 require the driver to get out of the vehicle to install and remove them, posing a safety hazard. The frame-type wheel chock device 100 of this application allows the driver to directly control the wheel chock 122 from inside the mining vehicle 200, enabling automatic wheel chock and non-wheel chock states and improving the driver's safety when using the wheel chock device. When the mining vehicle 200 stops on a slope, the driver needs to install a brake block 122 at the appropriate position according to the slope's inclination. This application uses a pair of arc-shaped connecting rods 121 and a pair of brake blocks 122, which can simultaneously abut against the two tires 210 on the same side, without considering the slope's inclination. When the mining vehicle 200 needs to stop urgently on a slope, the existing brake blocks 122 are inconvenient to install promptly, while the frame-type brake device 100 of this application responds faster and is more convenient, meeting the needs of emergency stops. The frame-type brake device 100 of this application has a wide range of applications and can be used on most engineering vehicles and special vehicles used in mines.
