Abstract

The present invention discloses a shock-resistant cold-insulating bracket assembly applied to a strong cold medium tank, and relates to the technical field of tank truck brackets. Compared with the traditional installation method of a tank truck, a welding bracket assembly is used as the basic structure for fixing the tank body, and the tank body position corresponding to the front position of the tank truck is ensured to be tilted upward. Its essence is to "actively" bear the "surge" phenomenon of the strong cold medium inside the tank body. On this basis, the overall fixing method is improved to a steel cable traction structure, which is specifically manifested in that the inertial force of the tank body itself is used as the "power source" to make the welding bracket assembly "actively" perform a downward angular deflection action and embodied in the working roller shaft, so as to promote the working roller shaft to move in the vertical direction. The purpose is to convert the angular deflection action caused by inertia into vertical direction movement, and then the tank truck's own suspension system "bears" the force generated by the tank body, thereby reducing the movement degree of the strong cold medium itself and the workload of the overall structure.

Description

Technical Field

[0001] The invention relates to the technical field of tank truck brackets, and in particular to a shock-resistant cold-insulating bracket assembly applied to a strong cold medium tank. Background Art

[0002] During the transportation of strong cold media, the first thing to do is to consider the physical / chemical properties of the medium and select tanks of corresponding specifications. Secondly, considering issues such as medium expansion, the loading capacity of the strong cold medium will not exceed 80% of the tank volume. The tank and chassis in common tank trucks are fixedly connected as one, so the suspension system in the tank truck will also act on the tank.

[0003] It is important to note that due to inertia, the tank body and the strong cold medium inside it will undergo "inertial movement" relative to the chassis (vehicle body), and the strong cold medium inside it will undergo "secondary inertial movement" relative to the tank body, which is specifically manifested as the strong cold medium "accelerating" the impact on the tank body. If a completely fixed structure is used between the tank body and the vehicle body, the suspension system will not "reduce" the impact of the medium on the tank body, and may even increase the material burden of the fixed structure and the tank body itself due to further expansion during the continuous "impact" process of the medium, such as welding, riveting and other fixed structures. This application proposes a solution to this problem. Summary of the invention

[0004] The purpose of the present invention is to provide a shock-resistant cold-insulating bracket assembly for a strong cold medium tank. For tank trucks used to transport strong cold media, conventional vehicle-mounted suspension systems are not fully applicable. Specifically, the tank body relative to the vehicle body and the strong cold medium relative to the tank body will undergo "inertial movement" to varying degrees, thereby increasing the structural characteristics of the tank body itself and the material burden of the fixed structure.

[0006] A cooperative roller shaft and a working roller shaft are sequentially arranged on one side of the chassis corresponding to the front roller shaft, a primary steel cable is connected between the front roller shaft and the cooperative roller shaft, and a secondary steel cable is arranged between the cooperative roller shaft and the working roller shaft;

[0007] Directional guide columns are installed on the lower curved surface of the working roll shaft and are arranged linearly and equidistantly along the width direction of the chassis. The directional guide columns are slidingly connected to the chassis in the vertical direction, and high-strength springs are arranged at positions on the directional guide columns corresponding to the upper surface of the chassis. Triangular pressure rods are rotatably installed at both ends of the working roll shaft, and the setting position of the triangular pressure rods corresponds to the upper curved surface of the leaf spring.

[0008] It is further configured as follows: a spring damper is rotatably mounted on the outer wall direction of the welding bracket assembly corresponding to the width direction of the chassis, the spring damper is linearly equidistantly arranged along the length direction of the welding bracket assembly, and a positioning fixing plate corresponding to the spring damper is installed on the chassis.

[0009] It is further configured that: the end position of the spring damper corresponding to the positioning fixing plate is configured as a ball head, and a ball sleeve corresponding to the ball head is installed on the positioning fixing plate.

[0010] It is further configured as follows: a front baffle is installed at the other end of the chassis corresponding to the front roller shaft, a directional arc seat corresponding to the front baffle is installed at the other end of the welding bracket assembly, and the outer wall of the front baffle on one side close to the directional arc seat is an arc surface.

[0011] It is further configured that: the center point of the circular arc surface of the front baffle and the directional arc seat and the rotation midpoint are on the same horizontal plane.

[0012] It is further configured as follows: a hydraulic cylinder assembly is installed at a position of the chassis corresponding to the front baffle, a sliding seat slidably connected to the chassis is installed at the end position of the output shaft of the hydraulic cylinder assembly, a driving shaft seat corresponding to the sliding seat is rotatably installed on the welding bracket assembly, one end of the driving shaft seat corresponding to the sliding seat is configured as a ball head, and the driving shaft seat is movably connected to the sliding seat through the ball head.

[0013] It is further configured that: both ends of the first-level steel cable are respectively mounted on the front roller shaft and the cooperative roller shaft, and the length of the first-level steel cable is greater than the distance between the front roller shaft and the cooperative roller shaft;

[0014] The two ends of the secondary steel cable are respectively installed on the cooperative roller shaft and the upper surface of the chassis, and the secondary steel cable is located on the upper side of the working roller shaft, and the secondary steel cable is tangent to the upper curved surface of the working roller shaft.

[0015] It is further configured as follows: the setting direction of the cooperative roller shaft, the front roller shaft and the working roller shaft is parallel to the width direction of the chassis, and the cooperative roller shaft is rotationally connected to the chassis, and a decoding control assembly corresponding to the cooperative roller shaft is installed on the chassis.

[0017] The present invention has the following beneficial effects:

[0018] 1. The overall structure uses the welded bracket assembly as the direct structure to fix the tank body. The difference from the conventional tank truck structure is that the welded bracket assembly is restricted to be tilted upward along the corresponding position of the tank truck head. The purpose is to reduce the "surge" degree of the strong cold medium inside the tank body. The key lies in: changing the connection method of the welded bracket assembly relative to the chassis, forming a traction structure with the first-level steel cable and the second-level steel cable. During operation, the overall structure uses the inertia force of the tank body itself as the "power source" to prompt the welded bracket assembly to deflect from the upward tilt state, mainly to "consume" the impact of the strong cold medium on the tank body during the "surge" phenomenon;

[0019] 2. In combination with the above content, it is explained that the traction structure mainly acts on the working roll shaft, and the traction action causes the working roll shaft to be limited to sliding in the vertical direction. Its purpose is to transfer the "inertia effect" generated by the tank body to the chassis, and the chassis actively bears the responsibility, mainly to reduce the movement degree of the strong cold medium itself and the workload of the overall structure, and perceive the movement process of the overall structure according to the decoding control assembly, and further control the oil pressure of the hydraulic cylinder assembly and the auxiliary hydraulic rod group.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] For the tank loaded with strong cold medium, due to the influence of inertia, the tank and the strong cold medium inside it will have "inertial movement" relative to the chassis (vehicle body). The key is the "surge" phenomenon generated by the strong cold medium inside the tank, which aggravates the material burden and work burden in the overall structure. The following technical solutions are proposed:

[0031] Reference Figures 1 to 6 The anti-seismic cold-insulation bracket assembly applied to the strong cold medium tank in this embodiment includes a chassis 1 and a welding bracket assembly 2 and a leaf spring 6 arranged at the upper position and the lower position of the chassis 1. A front roller shaft 3 is installed at one end of the lower side of the welding bracket assembly 2 and is rotatably connected to the chassis 1 through the front roller shaft 3. The center point of the front roller shaft 3 of the welding bracket assembly 2 is set as the rotation midpoint, and the welding bracket assembly 2 is inclined upward with the horizontal direction of the rotation midpoint;

[0032] A cooperative roller shaft 9 and a working roller shaft 7 are sequentially arranged on one side of the chassis 1 corresponding to the front roller shaft 3. A primary steel cable 16 is connected between the front roller shaft 3 and the cooperative roller shaft 9, and a secondary steel cable 17 is arranged between the cooperative roller shaft 9 and the working roller shaft 7.

[0033] A directional guide column 20 is installed on the lower curved surface of the working roll shaft 7 and is arranged linearly and equidistantly along the width direction of the chassis 1. The directional guide column 20 and the chassis 1 are slidably connected in the vertical direction, and a high-strength spring 10 is arranged on the directional guide column 20 corresponding to the upper surface of the chassis 1. A triangular pressure rod 18 is rotatably installed at the two ends of the working roll shaft 7. The setting position of the triangular pressure rod 18 corresponds to the upper curved surface of the leaf spring 6.

[0034] The welding bracket assembly 2 is rotatably mounted with a spring damper 5 in the direction of the outer wall corresponding to the width direction of the chassis 1. The spring damper 5 is linearly equidistantly arranged along the length direction of the welding bracket assembly 2. A positioning fixing plate 8 corresponding to the spring damper 5 is installed on the chassis 1. The end position of the spring damper 5 corresponding to the positioning fixing plate 8 is set to a ball head, and a ball sleeve corresponding to the ball head is installed on the positioning fixing plate 8.

[0035] Working principle: The welding bracket assembly 2 in the present invention is used for welding to the basic structure of the tank body, and the chassis 1 is used as the chassis structure of the tank truck. The chassis 1 is set at a position completely horizontal to the ground. The structural parameters of the two are not repeated here. However, it should be noted that it is not installed on the welding bracket assembly 2 in a conventional completely horizontal manner. Figure 3 As shown, when the welding bracket assembly 2 is initially installed, it is necessary to ensure that there is an angle of A° between the welding bracket assembly 2 and the chassis 1, which can be understood as follows: the tank body portion close to the front of the tank truck is tilted upward. If the strong cold medium is loaded at 80% of the maximum loading capacity, the remaining space inside the left side of the tank body is smaller than the remaining space inside the right side. Therefore, when the tank truck is affected by inertia, the strong cold medium will generate a "surge" phenomenon in the direction pointing to the front of the tank truck. However, because the tank body itself has formed a slope, when the strong cold medium generates a "surge" phenomenon, the gravitational potential energy has already "consumed" the kinetic energy of the strong cold medium during the "surge", thereby preliminarily reducing the movement degree of the strong cold medium and the impact degree on the tank body.

[0036] It is further explained that the integral welded bracket assembly 2 is not fixed to the chassis 1 in a completely fixed form, but is slightly deflected at the rotation midpoint formed by the front roller shaft 3. In order to maintain the angle A°, the hydraulic cylinder assembly 11 is used as a moving part, and the hydraulic cylinder assembly 11 drives the slide 12 to move to the front position of the tank truck, cooperates with the drive shaft seat 13 to form an angle, and is combined with Figure 6 The auxiliary hydraulic rod group 19 plays a small supporting role for the welding bracket assembly 2, but it depends on the liquid medicine cylinder assembly 11, and the auxiliary hydraulic rod group 19 is fixed in the center area of ​​the leaf spring 6, so it will not promote the deformation process of the leaf spring 6;

[0037] For the angular deflection of the welding bracket assembly 2, the spring damper 5 and the positioning fixing plate 8 need to be further utilized. When the angle of the welding bracket assembly 2 is reduced, the spring damper 5 and the positioning fixing plate 8 are utilized to perform a small part of the buffering protection.

[0038] Embodiment 2:

[0039] Supplementary explanation for the welding bracket assembly and chassis in the first embodiment:

[0040] A front baffle plate 14 is installed at the other end position of the chassis 1 corresponding to the front roller shaft 3, and a directional arc seat 15 corresponding to the front baffle plate 14 is installed at the other end position of the welding bracket assembly 2. The outer wall of the front baffle plate 14 and the directional arc seat 15 on one side close to each other is an arc surface, and the center point of the arc surface in the front baffle plate 14 and the directional arc seat 15 is on the same horizontal plane as the midpoint of rotation.

[0041] Solution description: In combination with the first embodiment, since the welding bracket assembly 2 and the chassis 1 are not fixedly connected, the tank body carrying the strong cold medium will also be affected by inertia and produce a forward "inertial movement trend" during the specific use process. During long-term operation, the front roller shaft 3 corresponding to the midpoint of rotation will also be subjected to greater stress changes. For this purpose, a front baffle 14 and a directional arc seat 15 are added, wherein the front baffle 14 is fixed on the chassis 1, and the directional arc seat 15 is installed on the welding bracket assembly 2, and a front baffle 14 is further provided. The center point of the arc surface in the baffle 14 and the directional arc seat 15 is on the same horizontal plane as the midpoint of rotation. It can be understood that: the front baffle 14 and the directional arc seat 15 will not affect the angular deflection movement of the welding bracket assembly 2, but on the contrary, they play a rearward supporting role for the welding bracket assembly 2. Then the "inertial force influence" generated by the tank body and the strong cold medium inside it directly acts on the tank truck, avoiding the forward "inertial movement tendency" of the tank body and aggravating the damage of the front roller shaft 2. This part is mainly used to represent the supplementary scheme in Example 1.

[0042] Embodiment three:

[0043] Combined with the first and second embodiments, the traction structure and the decoding control assembly are supplemented as follows:

[0044] A hydraulic cylinder assembly 11 is installed at a position of the chassis 1 corresponding to the front baffle 14, a slide seat 12 slidably connected to the chassis 1 is installed at the end position of the output shaft of the hydraulic cylinder assembly 11, a drive shaft seat 13 corresponding to the slide seat 12 is rotatably installed on the welding bracket assembly 2, one end of the drive shaft seat 13 corresponding to the slide seat 12 is set as a ball head, and the drive shaft seat 13 is movably connected to the slide seat 12 through the ball head, and both ends of the primary steel cable 16 are respectively installed on the front roller shaft 3 and the cooperative roller shaft 9, and the length of the primary steel cable 16 is greater than the distance between the front roller shaft 3 and the cooperative roller shaft 9;

[0045] The two ends of the secondary steel cable 17 are respectively installed on the upper surface of the cooperative roller shaft 9 and the chassis 1, and the secondary steel cable 17 is located on the upper side of the working roller shaft 7. The secondary steel cable 17 is tangent to the upper curved surface of the working roller shaft 7. The setting direction of the cooperative roller shaft 9, the front roller shaft 3 and the working roller shaft 7 is parallel to the width direction of the chassis 1, and the cooperative roller shaft 9 and the chassis 1 are rotatably connected. A decoding control assembly 4 corresponding to the cooperative roller shaft 9 is installed on the chassis 1, and a vertically arranged auxiliary hydraulic rod group 19 is installed at the center point of the triangular pressure rod 18. A through groove corresponding to the triangular pressure rod 18 and the auxiliary hydraulic rod group 19 is opened on the chassis 1, and the end position of the auxiliary hydraulic rod group 19 is installed at the center point of the upper curved surface of the leaf spring 6.

[0046] Solution Description: Combined with Figure 3 and Figure 4 To illustrate, when the angle A° between the welding bracket assembly 2 and the chassis 1 is reduced, that is, the welding bracket assembly 2 is deflected downward, during this process, the front roller shaft 3 thereof rotates clockwise, and for this purpose, it is necessary to further limit the connection mode of the primary steel cable 16 corresponding to the front roller shaft 3 and the cooperative roller shaft 9, which is specifically manifested as follows: when the front roller shaft 3 rotates clockwise, a part of the primary steel cable 16 is continuously wound around the front roller shaft 3, and another part of the primary steel cable 16 is extended from the cooperative roller shaft 9. The key is to utilize the angle deflection action of the welding bracket assembly 2 to synchronously drive the cooperative roller shaft 9 to rotate synchronously clockwise;

[0047] Similarly, when the cooperative roller shaft 9 rotates clockwise, a portion of the secondary steel cable 17 corresponding to the cooperative roller shaft 9 will also be wound around the cooperative roller shaft 9. Since the other end of the secondary steel cable 17 is fixed on the chassis 1, the relative length of the secondary steel cable 17 is reduced. Figure 6 and Figure 5 , presses the working roll shaft 10 to move downward. In this process, each high-strength spring 10 is compressed first, so as to initially play a role of buffer protection. However, the key is to squeeze the leaf spring 6 downward through the triangular pressure rod 18, so that the leaf spring 6 bears the pressure from the working roll shaft 7, and the auxiliary hydraulic rod group 19 therein will also undergo a corresponding compression process. It can be understood that the angular deflection action of the welding bracket assembly 2 in the overall structure is based on the "inertia force" generated by the tank body and the strong cold medium inside it as the "power source", and finally through the traction structure, the chassis 1 "actively bears" the "inertia influence" from the tank body;

[0048] It is also necessary to further explain that: because the cooperative roller shaft 9 is rotatably connected to the chassis 1, it is necessary to synchronously use the decoding control assembly 4, which mainly includes a decoder and a controller. The decoder is used to detect the rotation angle and rotation time of the cooperative roller shaft 9. Because of safety considerations, it is necessary to require that the welding bracket assembly 2 can only perform a small angle deflection. The optimal state is that the welding bracket assembly 2 maintains a relatively stable state, but due to the influence of inertia, the stress generated when the strong cold medium "surges" is very large, causing the hydraulic cylinder assembly 12 to move slightly in a straight line in the direction of the front roller shaft 3, and then the liquid in the hydraulic cylinder assembly 11 The pressurized oil is compressed, causing the internal oil pressure to increase or even disappear, and the decoder senses the rotation state of the cooperative roller 9 to reversely calculate the "inertia force". It should be noted that the inertia force is not a mechanical unit, so the "inertia force" calculated by the decoder is only used to represent the stress change to reversely sense the "pressure" directly borne by the chassis 2. This is integrated into the hydraulic cylinder assembly 11 and the auxiliary hydraulic rod group 19, and the oil pressure is reversely supplemented according to the calculated "inertia force". The reverse supplemented oil pressure "neutralizes" the impact force of the strong cooling medium on the tank body and reduces the "surge degree" of the strong cooling medium inside the tank body. This part can refer to the air spring in the vehicle suspension system.

[0049] In summary: Compared with the installation method of the tank truck, the welding bracket assembly is used as the basic structure for fixing the tank body, and the tank body position corresponding to the front position of the tank truck is ensured to be tilted upward. Its essence is to "actively" bear the "surge" phenomenon of the strong cold medium inside the tank body. On this basis, the overall fixing method is improved to a steel cable traction structure, which is specifically manifested as follows: using the inertia force of the tank body itself as the "power source", the welding bracket assembly is "actively" deflected at a downward angle and reflected in the working roller shaft, prompting the working roller shaft to move in the vertical direction. The purpose is to convert the angular deflection caused by inertia into vertical movement, and then the tank truck's own suspension system "bears" the force generated by the tank body, reducing the movement degree of the strong cold medium itself and the workload of the overall structure.
