Description

Technical Field

[0001] The present invention belongs to the technical field of LNG gas cylinders, and in particular relates to a vehicle-used LNG gas cylinder bracket. Background Art

[0002] Vehicle LNG cylinders are vehicle liquefied natural gas storage tanks, mostly used in heavy-duty vehicles. LNG cylinders are generally installed on brackets, which are then installed on the base frame at the back of the vehicle. The overall shape of the LNG cylinder is a cylindrical structure.

[0003] However, most of the existing vehicle LNG cylinder brackets do not have the rotating cover-connected first and second plate structures set on the bracket seat, so it is impossible to tightly cover the upper end surface of the gas cylinder placed on the bracket seat. Due to the vibration of the car's driving, the gas cylinder will vibrate and slip off from the top of the bracket seat. In addition, it usually does not have a buffering and vibration-damping layer and a wear-resistant and anti-skid layer, which will greatly reduce the buffering, vibration-damping and anti-skid properties of the gas cylinder on the bracket seat.

[0004] Moreover, if the heavy truck needs to transport goods to a distant place, the liquefied natural gas in the current single gas cylinder is not enough, and there is no place to install another gas cylinder bracket on the car, which will cause the liquefied natural gas in the gas cylinder of the car to be used to transport goods to a distant place to be insufficient. Summary of the Invention

[0005] The purpose of the present invention is to provide a vehicle-use LNG cylinder bracket to solve the problems in the prior art that the vibration of the vehicle during driving may cause the gas cylinder to vibrate and slip off from the top of the bracket seat, the cushioning and anti-slip properties of the gas cylinder on the bracket seat are low, and since there is no place to install another gas cylinder bracket on the vehicle, the liquefied natural gas in the gas cylinder of the vehicle is insufficient when transporting goods to a distant place.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A vehicle LNG cylinder bracket, comprising a first bracket body and a second bracket body, the first bracket body and the second bracket body both consisting of a bracket seat, a rotating shaft, a mounting plate, a first set of plates, a second set of plates, a supporting plate, and a rib plate, the first bracket body is equipped with a first gas cylinder, the second bracket body is equipped with a second gas cylinder, the upper folding and clamping parts of the first set of plates and the second set of plates are threadedly provided with a fastening bolt group, the fastening bolt group consists of a bolt cap, a stud, an extrusion washer, and a dial plate, the rotating shaft is fixedly set on the bracket seat, the lower ends of the first set of plates and the second set of plates are respectively rotatably connected to the rotating shaft, the supporting plate is arranged on the upper outer wall surface of the first set of plates and the second set of plates, and the structural parts used in this new model, unless otherwise specified, are made of 304 stainless steel, which has high strength, corrosion resistance, and is easy to weld.

[0007] Preferably, the buffer and vibration reduction layer is a commonly used polyurethane rubber pad, which has elastic buffering properties and can effectively buffer and reduce vibrations during automobile transportation. The wear-resistant and anti-slip layer is a pad made of high-density polyethylene material, and its surface is densely covered with concave and convex grid anti-slip patterns. The high-density polyethylene material body has high wear resistance, which can improve durability and anti-slip properties between the gas cylinder.

[0008] Preferably, there are two ribs, one of which is arranged between the support plate and the first set of plates, and the other is arranged between the support plate and the second set of plates. The cross-section of the ribs is a triangular structure. The stability of the triangular shape can greatly improve the structural stability between the support plate and the first set of plates and the second set of plates.

[0009] Preferably, there are two mounting plates and they are symmetrically arranged at both ends of the bracket seat, each mounting plate is provided with a mounting hole, the number of the mounting holes is two and they are symmetrically arranged with the vertical central axis of the side of a single mounting plate as the center, and a thread groove is provided on the support plate, and the mounting hole and the thread groove are vertically aligned, which can ensure that the mounting hole on the second bracket body is aligned with the thread groove on the first bracket body.

[0011] Preferably, the extrusion washer is made of an elastic damping silicone pad. When the stud is locked into the locking thread groove, the extrusion washer will be squeezed and deformed by the bolt cap and the inner wall of the countersunk groove, which not only seals the socket, but also the extrusion washer will generate vertical rebound force after being squeezed, which can improve the anti-rotation effect of the stud and the locking thread groove.

[0012] Preferably, the upper end of the shift plate is not higher than the top of the countersunk groove, and the top end surface of the folded and clamped part of the upper end of the first set of plates and the second set of plates is a flat surface and flush with the upper end surface of the support plate, ensuring that the second bracket body is stably and flatly installed on the upper end surface of the first bracket body.

DETAILED DESCRIPTION

[0025] See also Figure 1 、 Figure 2 、 Figure 3A vehicle LNG cylinder bracket includes a first bracket body 1 and a second bracket body 11. The first bracket body 1 and the second bracket body 11 are both composed of a bracket seat 2, a rotating shaft 21, a mounting plate 3, a first set plate 4, a second set plate 5, a supporting plate 7, and a rib plate 8. The first bracket body 1 is equipped with a first gas cylinder 10, and the second bracket body 11 is equipped with a second gas cylinder 101.

[0026] See also Figure 1 、 Figure 2 、 Figure 3 The rotating shaft 21 is fixedly welded to the bracket seat 2, and the lower ends of the first set of plates 4 and the second set of plates 5 are rotatably connected to the rotating shaft 21 respectively. The supporting plate 7 is welded to the outer wall surface of the upper end of the first set of plates 4 and the second set of plates 5. There are two mounting plates 3 and they are symmetrically welded to the two ends of the bracket seat 2. Each mounting plate 3 is provided with a mounting hole 31. The number of mounting holes 31 is two and they are symmetrically arranged with the vertical central axis of the side of a single mounting plate 3 as the center. A threaded groove 71 is provided on the supporting plate 7. The mounting hole 31 and the threaded groove 71 are vertically aligned, which can ensure that the mounting hole 31 on the second bracket body 11 is aligned with the threaded groove 71 on the first bracket body 1, and convenient and stable installation can be achieved.

[0027] See also Figure 1 、 Figure 2 、 Figure 3 There are two ribs 8, one of which is welded between the supporting plate 7 and the first set of plates 4, and the other is welded between the supporting plate 7 and the second set of plates 5. The cross-section of the rib 8 is a triangular structure.

[0028] See also Figure 1 、 Figure 4 、 Figure 5 、 Figure 6The first set of plates 4 and the second set of plates 5 are folded and connected at the upper end thereof, and a fastening bolt group 6 is provided with a threaded connection. The fastening bolt group 6 consists of a bolt cap 61, a stud 62, an extrusion washer 63, and a paddle plate 64. The bolt cap 61 and the stud 62 are fixedly welded, the paddle plate 64 is welded to the top of the bolt cap 61, and the extrusion washer 63 is bonded to the lower end of the bolt cap 61. The extrusion washer 63 is made of an elastic damping silicone pad. When the stud 62 is locked into the locking thread groove 41, the extrusion washer 63 will be squeezed and deformed by the inner wall of the bolt cap 61 and the countersunk groove 52, which can not only seal the jack 51, but also be squeezed. The extruded washer 63 at the back will generate vertical rebound force, which can improve the anti-rotation effect of the stud 62 and the locking thread groove 41. The upper end of the second set of plates 5 is provided with a socket 51 and a countersunk groove 52, and the upper end of the first set of plates 4 is provided with a locking thread groove 41. The stud 62 passes through the socket 51 and is threadedly connected to the locking thread groove 41. The bolt cap 61, the extruded washer 63, and the paddle plate 64 are integrally sunk in the countersunk groove 52. There are two paddle plates 64 and they are arranged in a circle with the center of the circular cross-section of the bolt cap 61 as the center when viewed from above. The top cross-section of the paddle plate 64 is an arc-shaped structure, which ensures that the fingers can rotate the stud 62 conveniently and efficiently.

[0029] See also Figure 4 、 Figure 5 、 Figure 6 The inner wall surface of the paddle 64 is bonded with a spring pad 641, which is a rubber elastic pad. When the finger rotates the paddle 64, it will squeeze and buffer the spring pad 641, thereby improving the comfort of the finger during rotation and avoiding finger squeezing and wear.

[0030] See also Figure 1 、 Figure 3 、 Figure 4 The upper end of the paddle plate 64 is not higher than the top of the countersunk groove 52, and the top surface of the folded and clamped part of the upper ends of the first set of plates 4 and the second set of plates 5 is a flat surface and flush with the upper end surface of the supporting plate 7, ensuring that the second bracket body 11 is stably and flatly installed on the upper end surface of the first bracket body 1.

[0031] See also Figure 1 The inner wall surfaces of the bracket seat 2, the first set of plates 4, and the second set of plates 5 are all bonded with a buffering and vibration-damping layer 22. The buffering and vibration-damping layer 22 is a commonly used polyurethane rubber pad with elastic buffering properties, which can effectively buffer and reduce vibrations during automobile transportation. A wear-resistant and anti-slip layer 23 is bonded to the inner wall surface of the buffering and vibration-damping layer 22. The wear-resistant and anti-slip layer 23 is a cushion layer made of high-density polyethylene material, and its surface is densely covered with concave and convex grid anti-slip patterns. The high-density polyethylene material body has high wear resistance, which can improve durability and anti-slip properties between the gas cylinder.

[0032] The working principle of this solution is: first, install the bracket seat 2 on the base frame on the back of the car through the mounting holes 31 on both sides and the bolts, and then place the first gas cylinder 10 in the bracket seat 2. Next, rotate the first set of plates 4 and the second set of plates 5 on both sides and fold them to cover the first gas cylinder 10 as a whole, and then thread the stud 62 into the locking thread groove 41, so that the upper end surface of the first gas cylinder 10 placed on the bracket seat 2 is also tightly covered, avoiding the gas cylinder from vibrating and slipping from the top of the bracket seat 2 due to the vibration of the car. In addition, the buffering and vibration reduction layer 22 and the wear-resistant and anti-skid layer 23 are greatly improved. The buffering, vibration reduction and anti-skid properties of the first gas cylinder 10 tightly mounted on the bracket seat 2.

[0033] If the place where the heavy-duty vehicle needs to transport goods is far away and the liquefied natural gas in the current first gas cylinder 10 is insufficient, the second bracket body 11 that has been covered and installed with the second gas cylinder 101 can be installed as a whole on the upper end of the first bracket body 1, and then the bolts are passed through the aligned mounting holes 31 and then threadedly locked through the thread grooves 71, so that the second bracket body 11 with the second gas cylinder 101 can be conveniently and stably installed on the upper end of the first bracket body 1, avoiding the situation where the liquefied natural gas in the gas cylinder of the vehicle is insufficient when transporting goods to a distant place.
