Description

Technical Field

[0001] The utility model relates to the technical field of fuel tank trucks, in particular to a wheel stopper placement device for fuel tank trucks. Background Art

[0002] When fuel is supplied to a fuel tank truck, in order to prevent safety accidents such as the fuel tank opening or the oil outlet of the ground well pipeline from being damaged due to accidental driving during the operation of the fuel tank truck, wheel stoppers are usually equipped on the vehicle body.

[0003] When the fuel tank truck is operating, the operator takes out the wheel stopper from the storage box on the vehicle body and places it in the forward direction of the wheels of the fuel tank truck to fix the wheels; after the operation of the fuel tank truck is completed, the operator retracts the wheel stopper into the storage box on the vehicle body and notifies the driver to drive away. First, for the above operations, the operator needs to memorize the operating procedures. If the operator is negligent during the operation and fails to place the wheel stopper, there will be a risk of accidental driving; if the operator forgets to put the wheel stopper back in place after the operation, the wheel stopper will be worn during driving. Secondly, since the fuel tank truck is a heavy vehicle with a large vehicle body, it takes a long time for the operator to retract all the wheel stoppers and then go around to the cab to notify the vehicle condition, which affects the operation efficiency. Content of the Utility Model

[0004] In order to solve the deficiencies of the above-mentioned prior art, the utility model provides a wheel stopper placement device for a fuel tank truck, which can realize interlocking with the brake of the fuel tank truck, ensure operation safety and improve operation efficiency.

[0005] The technical solution of the utility model is as follows: a wheel stopper placement device for a fuel tank truck, including a storage box installed on the fuel tank truck. One side of the storage box is provided with a storage opening for inserting the wheel stopper. A baffle is fixed on the other side of the storage box. A proximity sensor and a swinging member are provided at a position of the storage box close to the baffle. The proximity sensor is fixed on the storage box and is communicatively connected with the brake system of the fuel tank truck. The swinging member is rotatably installed in the storage box, and one end of the swinging member has a driving portion that is driven to rotate by the thrust of the wheel stopper, and the other end of the swinging member has a sensing portion that moves synchronously closer to or farther away from the proximity sensor along the rotation path of the swinging member. When the wheel stopper is placed in the storage box, the driving portion of the swinging member is subjected to the thrust of the wheel stopper and drives the swinging member to rotate. The sensing portion of the swinging member moves closer to the proximity sensor. The proximity sensor sends a brake release signal to the control brake system. The driver can directly know the return situation of the wheel stopper in the cab without the need for the operator to notify, improving the operation efficiency. At this time, the fuel tank truck can be normally started by ignition, and there will be no situation of the wheel stopper being damaged by driving. After the wheel stopper is taken out, the sensing portion returns away from the proximity sensor along with the swinging member. The proximity sensor sends a brake signal to the control brake system, and the fuel tank truck cannot move, thus avoiding the risk of accidental driving and ensuring operation safety.

[0006] The bottom of the storage box is inclined downward along the moving direction of the wheel stopper. The inclined setting of the bottom of the storage box enables the retaining wheel to slide to the baffle under the action of gravity, improving the convenience of the operation for the retaining wheel to return to its position.

[0007] A rotating shaft is fixed on the swinging member. Both ends of the rotating shaft penetrate and are rotatably installed on the side plates of the storage box. The rotating shaft is located at a position deviating from the center of gravity of the swinging member, and the sensing portion moves along the direction away from the sensor under the action of gravity.

[0008] A rotating shaft is fixed on the swinging member. Both ends of the rotating shaft penetrate and are rotatably installed on the side plates of the storage box. A reset member for driving the sensing portion to move along the direction away from the sensor is provided on the swinging member.

[0009] The reset member is a spring. Both ends of the spring are respectively connected to the sensing portion and the baffle.

[0010] The cross-section of the swinging member is U-shaped. The U-shaped opening of the swinging member faces the baffle, and the two sides of the U-shaped opening of the swinging member are located on different sides of the baffle and respectively form the driving portion and the sensing portion.

[0011] The proximity sensor is fixed under the top plate of the storage box through a mounting plate, and the sensing head of the proximity sensor faces the sensing portion.

[0012] A limiting member for restricting the reverse removal of the retaining wheel entering the storage box from the storage box is fixed at a position near the lower part of the storage opening of the storage box.

[0013] The limiting member is a fixed shaft. Both ends of the fixed shaft are fixedly connected to the side plates of the storage box. The minimum distance between the fixed shaft and the top plate above the storage opening is greater than the height of the wheel stopper. Using the fixed shaft as the limiting member can limit the retaining wheel placed in the storage box at the storage opening. When the vehicle encounters a bumpy road section or a speed bump, it can prevent the retaining wheel from sliding outwards.

[0014] A sleeve is sleeved on the fixed shaft. The surface of the sleeve is in rolling contact with the bottom of the retaining wheel. The setting of the sleeve enables the retaining wheel to slide into the storage box, reducing the resistance when entering the storage box.

[0015] The beneficial effects of the present utility model are as follows: In this solution, by setting a storage box, a swinging member, and a proximity sensor, when the wheel chock is placed in the storage box, the driving part of the swinging member is pushed by the wheel chock and drives the swinging member to rotate. The sensing part of the swinging member moves closer to the proximity sensor, and the proximity sensor sends a brake release signal to the control braking system. The driver can directly know the return situation of the wheel chock in the cab without the need for an operator to notify, improving the operation efficiency. At this time, the refueling vehicle can be normally started by ignition, and there will be no situation of accidentally hitting the wheel chock during driving; after the wheel chock is taken out of the storage, the sensing part moves away from the proximity sensor as the swinging member resets, and the proximity sensor sends a braking signal to the control braking system, and the refueling vehicle cannot move forward, thus avoiding the risk of accidental driving and ensuring operation safety.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To enable those skilled in the art to better understand the technical solutions in the present utility model, the following clearly and completely describes the technical solutions in the present utility model with reference to the accompanying drawings. Other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1-3As shown in the figure, the present utility model provides a wheel chock placement device for a refueling vehicle, which includes a storage box 1 installed on the refueling vehicle. A placement opening 101 for inserting the wheel chock 2 is provided on one side of the storage box 1, and a baffle 102 is fixed on the other side of the storage box 1. Specifically, in this embodiment, the storage box 1 is composed of a top plate 103 and a frame body. The top plate 103 is fixed on the vehicle body of the refueling vehicle by bolts. The frame body is a polygon bending plate formed by bending a plate material with the same cross-sectional shape as the wheel chock, and is welded and fixed under the top plate 103. The top plate 103, the bending plate and the baffle 102 enclose a placement space for accommodating the wheel chock 2. A proximity sensor 4 and a swinging member 3 are provided at a position of the storage box 1 close to the baffle 102. The proximity sensor 4 is fixed on the storage box 1 and is communicatively connected to the braking system of the refueling vehicle. The swinging member 3 is rotatably installed in the storage box 1, and one end of the swinging member 3 has a driving portion 301 that drives the swinging member 3 to rotate under the thrust of the wheel chock 2. The other end of the swinging member 3 has an induction portion 302 that moves synchronously closer to or farther away from the proximity sensor 4 along the rotation path of the swinging member 3. The proximity sensor 4 cooperates with the induction portion 302 to send a signal to interlock and control the braking system. In some embodiments, the proximity sensor 4 is a capacitive proximity sensor 4. When the induction portion 302 approaches the proximity sensor 4 until the distance between the induction portion 302 and the proximity sensor 4 is less than the detection distance of the proximity sensor 4, the proximity sensor 4 generates an in-position signal. In other embodiments, the proximity sensor 4 can also be an inductive proximity sensor 4 or a magnetic proximity sensor 4. At this time, the induction portion 302 is correspondingly made of a metal material and a magnetic material.

[0025] As Figure 1 shown in the figure, when the wheel chock 2 is placed in the placement space of the storage box 1, the wheel chock generates a thrust in the same direction as the movement direction of the wheel chock on the driving portion 301 of the swinging member 3. The driving portion 301 drives the induction portion 302 on the swinging member 3 to rotate together. The induction portion 302 approaches the proximity sensor 4 until the rear end of the wheel chock and the driving portion 301 abut against the baffle 102 together. At this time, the proximity sensor 4 sends an in-position signal, and correspondingly controls the braking system to send a brake release signal. The driver can directly know the return situation of the wheel chock 2 in the cab without the need for an operator to notify, thereby improving the operation efficiency in the entire operation process. And at this time, when the refueling vehicle is normally started by ignition, there will be no situation of accidentally injuring the wheel chock 2 during driving; As Figure 4 shown in the figure, after the wheel chock is taken out of the storage box 1, the swinging member 3 resets with the disappearance of the thrust, and the induction portion 302 rotates away from the proximity sensor 4 as the swinging member 3 resets. The proximity sensor 4 sends an out-of-position signal, and correspondingly controls the braking system to send a brake signal, so that the refueling vehicle cannot drive, thereby avoiding the risk of accidental driving and ensuring operation safety.

[0026] Furthermore, in order to improve the convenience of the process of placing the wheel stopper into the storage box 1, the bottom of the storage box 1 is inclined downward along the moving direction of the wheel stopper 2. By setting the bottom of the storage box 1 as an inclined plane structure, after the wheel stopper enters the storage box 1, it can slide to the position of the baffle 102 under the action of gravity.

[0027] In Embodiment 1, a rotating shaft 5 is fixed on the swinging member 3. Both ends of the rotating shaft 5 penetrate and are rotatably installed on the side plates of the storage box 1. Specifically, both ends of the rotating shaft 5 have threaded portions, and after the threaded portions penetrate the side plates of the storage box 1 (i.e., the position of the polygonal bending plate close to the top plate 103), they are threadedly connected with nuts. The rotating shaft 5 is located at a position deviating from the center of gravity of the swinging member 3, and the sensing portion 302 moves along the direction away from the sensor under the action of gravity. Preferably, in this embodiment, the cross-section of the swinging member 3 is U-shaped, the U-shaped opening of the swinging member 3 faces the baffle 102, and the two sides of the U-shaped opening of the swinging member 3 are located on different sides of the baffle 102 and respectively form the driving portion 301 and the sensing portion 302. Specifically, the swinging member 3 is formed by welding a round rod and an L-shaped plate. The round rod forms the driving portion 301 of the swinging member 3, and the portion of the L-shaped plate parallel to the round rod forms the sensing portion 302 of the swinging member 3. The rotating shaft 5 is welded and fixed at the connection position of the round rod and the L-shaped plate. The weight of the L-shaped plate is greater than that of the round rod. Taking the rotating shaft 5 as the fulcrum, the entire swinging member 3 rotates under its own weight, driving the sensing portion 302 to move along the direction away from the sensor until the end of the L-shaped plate abuts against the back side of the baffle 102.

[0028] The proximity sensor 4 is fixed below the top plate 103 of the storage box 1 through the mounting plate 6, and the sensing head of the proximity sensor 4 faces the sensing portion 302. Specifically, the mounting plate 6 is an L-shaped bending plate integrally processed at the end of the top plate 103. The horizontal section of the L-shaped bending plate is flush with the top plate 103, and the vertical section of the L-shaped bending plate extends downward above the baffle 102. The proximity sensor 4 is fixedly penetrated on the vertical section of the L-shaped bending plate; when the driving portion 301 of the swinging member 3 abuts against the baffle 102, the sensing portion 302 of the swinging member 3 is parallel to the vertical section of the L-shaped bending plate. At this time, the distance between the sensing portion 302 and the proximity sensor 4 on the L-shaped bending plate is the shortest, and the proximity sensor 4 cooperates to sense and generate a signal.

[0029] In order to limit the wheel stopper 2 placed in the storage box 1 at the storage opening 101 and prevent the wheel stopper from sliding out of the storage box 1 when the vehicle encounters a bumpy road section or a speed bump, as Figure 5As shown, a limiting member for restricting the reverse removal of the retaining wheel entering the storage box 1 from the storage box 1 is fixed at a position near the lower part of the storage opening 101 of the storage box 1. Specifically, the limiting member is a fixed shaft 8, and both ends of the fixed shaft 8 are fixedly connected to the side plates of the storage box 1 (i.e., the position of the polygonal bending plate far from the top plate 103), and the minimum distance between the fixed shaft 8 and the top plate 103 above the storage opening 101 is greater than the height of the wheel stopper 2.

[0030] In order to reduce the resistance when the retaining wheel enters and exits the storage box 1, a sleeve 9 is sleeved on the fixed shaft 8, and the surface of the sleeve 9 is in rolling contact with the bottom of the wheel stopper 2.

[0031] In Embodiment 2, as Figure 6 shown, the difference from Embodiment 1 is that the swing member 3 is rotatably connected to the storage box 1 through a rotating shaft 5, and a reset member for driving the sensing portion 302 to move in the direction away from the sensor is provided on the swing member 3. Specifically, the reset member is a spring 7, and both ends of the spring 7 are respectively connected to the sensing portion 302 and the baffle 102. The swing member 3 rotates under the thrust of the wheel stopper 2, driving the sensing portion 302 to move in the direction close to the proximity sensor 4. At this time, the spring 7 is in a stretched state. When the wheel stopper 2 is removed from the storage box 1, the driving portion 301 of the swing rod loses force, and the spring 7 contracts to drive the sensing portion 302 to reset away from the proximity sensor 4, that is, the swing member 3 rotates back to the initial state; in other embodiments, the reset member can be a torsion spring. There are two torsion springs, which are respectively located at the positions where both ends of the rotating shaft 5 penetrate the side plates of the storage box 1, and both ends of the torsion spring are fixedly connected to the corresponding side plates of the storage box 1 and the ends of the rotating shaft 5.

[0032] Taking Embodiment 1 as an example, according to the number of wheels of the refueling vehicle, this device is installed at the corresponding vehicle body position. During the refueling process of parking, the operator takes out the retaining wheels 2 in each storage box 1. In order to facilitate the taking and placing of the retaining wheels 2, a handle 201 is fixed on the outside of the retaining wheels 2. As the retaining wheels 2 are taken out, as Figure 4As shown, the driving part 301 of the swinging part 3 releases force, and the swinging part 3 rotates under the action of gravity, driving the sensing part 302 away from the proximity sensor 4 until the end of the sensing part 302 abuts against the back side of the baffle 102. At this time, the proximity sensor 4 is separated from the sensing part 302, and the braking system of the refueling vehicle is controlled to send a braking signal, making the refueling vehicle unable to drive, ensuring the safety of the operation; after the operator completes the operation, the wheel chocks 2 in front of each wheel are successively slid into the storage box 1 through the storage opening 101 of the storage box 1. The fixing rod is located in front of the wheel chock 2 to limit the wheel chock 2. The rear end of the wheel chock 2 pushes the driving part 301 of the swinging part 3 to move backward until it is pressed against the baffle 102 together with the driving part 301. The sensing part 302 moves to the sensing position of the proximity sensor 4 and always maintains sensing with the sensing plate. The braking system of the refueling vehicle is controlled to send a brake release signal. At this time, the driver in the cab can directly understand the return status of the wheel chock 2, and then start the ignition normally. The whole operation process is convenient, fast, safe and reliable.
