Description

Technical Field

[0001] This utility model relates to the field of fire truck parts processing, and in particular to a fire truck mounting assembly device. Background Technology

[0002] The chassis of a fire truck is equipped with a water tank and an end shell connected to the water tank. The space inside the end shell is used to install fire-fighting tools such as water pumps, coils, and ladders.

[0003] For the welding of the upper structure of fire trucks, one method is to prefabricate a tooling that matches the fire truck chassis, and then hoist the water tank and end shell onto the tooling for assembly and welding.

[0004] Among these factors, adjusting the position of the water tank and end shell on the tooling, ensuring the alignment of the joint between water tank 1 and the end shell and maintaining stability during the welding process are key factors affecting processing quality. In existing processing methods, the end shell assemblies are often brought close together, and then pressure blocks are used on the sides of the water tank and end shell to press the joint between them. During the pressing process, the end shell is adjusted to prevent it from deviating from the water tank, and then force is applied from the end of the end shell to press it firmly against the water tank.

[0005] In the existing processing, in order to facilitate the adjustment of the end shell and water tank, a gap of not less than 3 cm is usually left when the water tank and end shell are hoisted and placed. After the pressure block abuts against the joint of the end shell and water tank, during the process of pressing the end shell and water tank together, a large frictional force is generated between the pressure block and the end shell. This not only generates a lot of noise that affects the hearing of the operators on site, but also easily transmits a large lateral torque to the pressure block, causing damage to the extension and retraction drive structure of the pressure block.

[0006] Therefore, this application proposes a fire truck mounting assembly device to solve the problems existing in the prior art. Utility Model Content

[0024] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0025] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0026] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0029] In this utility model, such as Figure 1-5 As shown, a fire truck mounting assembly device is provided, comprising: a frame, the frame including two opposing side frames 3 and a support body 19 disposed between the two side frames 3, forming a fixed space for the upper structure between the two side frames 3, the fixed space being divided into a water tank area and an end shell area along the length direction of the side frames 3; a side locking assembly, installed on the side frames 3, including a first side locking member disposed at the junction of the water tank 1 area and the end shell 2 area, the first side locking member including a first telescopic member 4 telescopically installed on the side frames 3 and a first clamping block 5 installed inside the first telescopic member 4, the inner surface of the first clamping block 5 forming a fixed area corresponding to the water tank 1 area and a sliding area corresponding to the end shell 2 area, the first clamping block 5 having an abutment plate 6 slidably installed in the sliding area along the length direction of the side frames 3.

[0030] When using the fire truck mounting assembly device of this utility model, such as... Figure 1 As shown, the end shell 2 and water tank 1 are hoisted between two side frames 3, with water tank 1 located in the water tank area and end shell 2 located in the end shell area. The first telescopic component 4 drives the first clamping block 5 to press against the sides of water tank 1 and end shell 2. During the pressing process, the first clamping block 5 gradually adjusts the sides of end shell 2 and water tank 1 to align. After the first clamping blocks 5 on both sides of the side frames 3 of water tank 1 are stably engaged, the end shell 2 and water tank 1 are moved relative to each other along the length of the side frames 3 (preferably, the end shell 2 is pushed towards water tank 1) so that the joint between end shell 2 and water tank 1 is brought closer together to facilitate welding.

[0031] During the closing process of the end shell 2 and the water tank 1, compared with the prior art where the first clamping block 5 simultaneously abuts against the end shell 2 and the water tank 1, this utility model can reduce the lateral friction between the end shell 2 and the first clamping block 5 by utilizing the relative sliding of the abutment plate 6 and the first clamping block 5. Specifically, a lubricating medium (such as grease) can be arranged between the abutment plate 6 and the first clamping block 5 to reduce the coefficient of friction between the abutment plate 6 and the first clamping block 5. The coefficient of friction between the abutment plate 6 and the first clamping block 5 can also be reduced by turning, grinding, or other methods. It is easy to see that the sliding fit between the abutment plate 6 and the first clamping block 5 in this utility model is more effective in reducing the coefficient of friction. Compared with the method where the first clamping block 5 directly abuts against the end shell 2 and the water tank 1 simultaneously, it can reduce the lateral torque transmitted to the first clamping block 5 during the movement of the end shell 2, which is beneficial to maintaining the structural stability of the first telescopic member 4. In some embodiments, the frictional noise generated by the relative movement of the abutment plate 6 and the first clamping block 5 is less than the frictional noise generated by the direct frictional movement of the end shell 2 and the first clamping block 5, which can improve the working environment.

[0032] In a preferred embodiment, as shown in the figure, the first clamping block 5 is provided with a groove 7 in the sliding area, and the abutment plate 6 is provided with a slider 8 that can be slidably installed in the groove 7. The width of the slider 8 is smaller than the width of the groove 7.

[0033] like Figure 3 As shown, by providing the groove 7 and the slider 8, when the end shell 2 drives the abutment plate 6 to slide relative to the first clamping block 5, a constraint can be formed on the abutment plate 6 in the vertical direction to prevent the abutment plate 6 from moving away from the first clamping part. By making the width of the slider 8 smaller than the width of the groove 7, the flexibility of relative movement between the abutment plate 6 and the first clamping block 5 can be improved, and the groove 7 can also be used to store the lubricating medium.

[0034] In optional embodiments, such as Figure 4 As shown, the first clamping block 5 has a plurality of first lubrication grooves 9 spaced vertically in the sliding area, and the abutment plate 6 has a plurality of second lubrication grooves 10 spaced vertically on its surface facing the first clamping block 5. As shown, by providing the first lubrication grooves 9 and the second lubrication grooves 10, lubricating medium can be stored between the abutment plate 6 and the first clamping block 5, thereby improving the smoothness of movement of the abutment plate 6 relative to the first clamping block 5, and also reducing the contact area between the abutment plate 6 and the first clamping block 5, further reducing the friction between them.

[0035] In an optional embodiment, the first lubrication groove 9 may be provided only in the first clamping block 5, or the second lubrication groove 10 may be provided only in the abutment plate 6.

[0036] In a preferred embodiment, such as Figure 2 and Figure 5 As shown, a further optimization of the structure of this utility model is that the end of the first clamping block 5 away from the fixed area is inserted and connected to the abutment plate 6 along the length direction of the side frame 3; a lockable or unlockable insertion structure is provided between the top surface of the abutment plate 6 and the top surface of the first clamping block 5, and when the end of the abutment plate 6 away from the fixed area is inserted into the first clamping block 5, the insertion structure can lock and stop the abutment plate 6 from moving toward the fixed area.

[0037] like Figure 2 and Figure 5 As shown, by inserting the left end of the abutment plate 6 into the first clamping block 5, the position of the abutment plate 6 can be vertically positioned before it abuts against the end shell 2. The insert structure locks and stops the abutment plate 6, ensuring a stable connection between the abutment plate 6 and the first clamping block 5. After the abutment plate 6 abuts against the end shell 2, the insert structure can be unlocked. At this point, when the end shell 2 moves the abutment plate 6 towards the water tank 1, the left end of the abutment plate 6 separates from the insert position of the first clamping block 5. This allows the abutment plate 6 to have a certain amount of vertical movement relative to the first clamping block, further improving the flexibility and smoothness of its movement relative to the first clamping block.

[0038] When it is necessary to add lubricating medium to the abutment plate 6 and the first clamping block 5, the abutment plate 6 can be removed by unlocking the insert structure and moving it laterally, which facilitates the operation.

[0039] exist Figure 1 In the embodiment shown, for the structure of this utility model, a slot 11 is formed at the end of the first clamping block 5 away from the fixed area, and the abutment plate 6 is provided with a positioning protrusion 601 that can be inserted into the slot 11.

[0040] In the illustrated embodiment, more specifically regarding the structure of this utility model, the slot 11 passes through the end of the first clamping block 5 away from the water tank 1, and a cover plate 12 is installed on the end face of the first clamping block 5 away from the water tank 1, the cover plate 12 closing the slot 11.

[0041] like Figure 5 As shown, in order to enable the end shell 2 to quickly disengage the abutment plate 6 from the slot 11 during its movement toward the water tank 1, the depth of the slot 11 is less than or equal to 5mm. By setting the slot 11 as a through groove, it is easier to process the slot 11. The cover plate 12 is used to close the slot 11, which can limit the movement of the abutment plate 6.

[0042] exist Figure 1In the illustrated embodiment, more specifically, the insertion structure includes a lug 13 disposed on the top surface of the abutment plate 6 and a pin 14 disposed on the top surface of the first clamping block 5.

[0043] exist Figure 1 In the illustrated embodiment, more specifically regarding the structure of this utility model, the first telescopic member 4 includes a base 401 mounted on the side frame 3, a top rod 402 slidably mounted on the base 401, and the top rod 402 connected to the first clamping block 5; the first telescopic member 4 also includes a first connecting rod 403 hinged to the base 401, a second connecting rod 404 hinged to the first connecting rod 403, and a handle 405 connected to the first connecting rod 403, the second connecting rod 404 being hinged to the top rod 402.

[0044] like Figure 2 and Figure 3 As shown, when the first telescopic component 4 is extended or retracted, the operator can rotate the handle 405 to make the first connecting rod 403 and the second connecting rod 404 collinear with the top rod 402, thereby extending the first clamping block 5 outward through the top rod 402. When it is necessary to retract the first telescopic component 4, simply rotate the handle 405 to lift the hinged position of the first connecting rod 403 and the second connecting rod 404 to retract the top rod 402 away from the water tank 1.

[0045] In an alternative embodiment, the first telescopic member 4 can also be configured such that an electric telescopic rod or a hydraulic telescopic rod is directly connected to the first clamping block 5.

[0046] exist Figure 1 In the illustrated embodiment, for the structure of this utility model, more specifically, the side locking assembly further includes a second locking member installed on the side frame 3. The second locking member is correspondingly installed in the end shell 2 region. The second locking member includes a retractable second telescopic member 15 and a second clamping block 16 disposed on the second telescopic member 15.

[0047] like Figure 1 As shown, by setting a second locking member, the end shell 2 can be further clamped and fixed by the second telescopic member 15 driving the second clamping block 16 after the end shell 2 and the water tank 1 are pressed together and before formal welding, so as to further stabilize the end shell 2.

[0048] Regarding the structural configuration of the second telescopic member 15, the structure of the second telescopic member 15 can be configured to be consistent with the structure of the first telescopic member 4.

[0049] exist Figure 1In the embodiment shown, for the structure of this utility model, more specifically, the side frame 3 is provided with an end locking assembly on the side of the end shell 2 region away from the water tank 1 region. The end locking assembly includes a retractable third telescopic member 17 and a third clamping block 18 disposed on the third telescopic member 17.

[0050] like Figure 1 As shown, by such a configuration, the third telescopic member 17 can be used to drive the third clamping block 18 to abut against the end of the end shell 2 away from the water tank 1, so that the third telescopic member 17 can drive the end shell 2 to move toward the water tank 1.

[0051] Regarding the structural configuration of the third telescopic member 17, the structure of the third telescopic member 17 can be configured to be consistent with the structure of the first telescopic member 4.
