Description

Technical Field

[0001] This utility model relates to the field of tubular structure maintenance technology, and in particular to a combined bracket for maintaining tubular structures. Background Technology

[0002] A bracket is a support used to support objects. In existing support structures, the structure is monotonous and only serves a single supporting function.

[0003] Because anti-aircraft gun barrels are long and heavy, they need to be disassembled and reassembled during maintenance. This process requires the cooperation of multiple operators and is time-consuming, labor-intensive, and prone to safety hazards. Existing brackets can only provide support and cannot meet the needs of barrel disassembly, reassembly, and maintenance. Therefore, it is necessary to design a support device that can assist in barrel disassembly, reassembly, and maintenance. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing brackets that can only provide support and cannot meet the actual needs of disassembly, assembly, and maintenance of the tube. This invention provides a modular bracket for tube maintenance. The device adopts a detachable installation structure, allowing for easy disassembly of components during transportation and storage. This detachable assembly structure also allows for simple and convenient replacement of damaged parts, resulting in low maintenance costs. Furthermore, the assembled device forms a vertical ladder structure with a smaller top and a larger bottom, thus ensuring high stability.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model discloses a combined bracket for maintaining the tube shaft, including a support, a lifting assembly, and a connecting plate. Two supports are provided, symmetrically distributed. A tube shaft holder capable of vertical movement is mounted on the top of each support. The lifting assembly is located below the tube shaft holder and controls its lifting and lowering. The connecting plate is located below the supports and connects the bottoms of the two supports. Both the lifting assembly and the connecting plate are detachably connected to the supports, allowing the support, lifting assembly, and connecting plate to form a vertical ladder structure with a smaller top and a larger bottom. Because the entire device uses a detachable installation structure, the components can be disassembled during transportation and storage. The device is easy to disassemble, transport, and store. Its detachable assembly structure allows for simple replacement of damaged sections, making operation convenient and maintenance costs low. Furthermore, the assembled device forms a vertical ladder structure with a smaller top and a larger bottom, resulting in high stability. Working principle: This device is primarily used for the routine maintenance of tubular structures, such as gun barrels. In use, the device is first assembled to form a vertical ladder structure with a smaller top and a larger bottom. The tubular structure is then placed on top of two barrel holders. The height of the barrel holders is adjusted using the lifting assembly to ensure the barrel is at the appropriate height before maintenance.

[0007] As a further description of the above technical solution: the bracket includes a main rod, an upper crossbar, and a lower crossbar. There are two main rods, which are symmetrical and inclined inward from bottom to top. The upper crossbar is located above the two main rods, and the lower crossbar is located below the two main rods. The upper ends of the lower crossbar are provided with slots, and the lower ends of the connecting plate are provided with U-shaped protrusions. The U-shaped protrusions are engaged in the slots and connected by pins. This structural design makes it convenient and quick to operate when the connecting plate and the bracket need to be disassembled, simply by removing the pins and moving the connecting plate to separate it from the bracket.

[0008] As a further description of the above technical solution: the lifting assembly includes two jacks connected by a connecting rod. Each jack has a U-shaped base at its bottom, and the upper crossbar has a slot in the middle that fits the U-shaped base. When the entire bracket is assembled, the U-shaped bases of the two jacks are respectively located in the slots in the middle of the two upper crossbars. This structural arrangement allows the entire bracket, after assembly, to connect the upper and lower parts of the two supports through the cooperation of the lifting assembly and the connecting plate, thereby ensuring the stability of the entire bracket after assembly. The lifting assembly not only lifts the body tube bracket but also pulls and connects the upper parts of the two supports, thus reducing the number of structures in the entire device; that is, no other connecting rod structure needs to be installed at the top, thereby facilitating device assembly and reducing device cost.

[0009] As a further description of the above technical solution: a guide shaft is installed at the top of the main rod, and the body tube clamp includes a clamp and a sleeve. The top of the clamp is provided with a circular groove structure that can cooperate with the body tube. The sleeve is set at both ends of the clamp and is respectively sleeved on the guide shafts at the top of the two main rods. The bottom of the clamp contacts the top of the jack. When it is necessary to raise the height of the body tube clamp, the body tube clamp can be lifted along the guide shaft by the jack. When it is necessary to lower the height of the body tube clamp, the body tube clamp can be lowered along the guide shaft by releasing the jack.

[0010] As a further description of the above technical solution: the piston rod of the jack is provided with a lifting plate at the top, and the bottom of the card holder is provided with a lifting card hole. The lifting plate is engaged in the lifting card hole. The lifting card hole and the lifting plate are adapted to each other. Together with the U-shaped base at the bottom of the jack, the overall stability of the entire lifting assembly can be improved.

[0011] As a further description of the above technical solution: a strap is installed above the card holder, which can be used to bind and fix the body tube after the body tube is erected to ensure its stability.

[0012] As a further description of the above technical solution: one end of the strap is fixed to the upper opening of one end of the card holder, and the upper opening of the other end of the card holder is provided with an insertion hole. A shaft is provided in the insertion hole, and the strap is provided with Velcro. When it is necessary to bind the body tube, the strap is wrapped around the top of the body tube, then passed through the shaft in the insertion hole, and then fixed by Velcro. The operation is convenient and quick. Conversely, the Velcro is torn off and one end of the strap is pulled out.

[0013] As a further description of the above technical solution: the bottom of the bracket is equipped with multiple casters for assisting the movement of the bracket.

[0014] As a further description of the above technical solution: a tray is also provided above the two brackets, and tray insert shafts are provided on both sides of the tray. The two upper crossbars are provided with insertion holes that are adapted to the tray insert shafts. When the tray is installed, the tray insert shafts are inserted into the insertion holes. Maintenance and repair tools can be placed on the tray, thereby facilitating the maintenance and repair of the tube.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The device adopts a detachable installation structure, which allows the components to be disassembled during transportation and storage, making it convenient for transport and storage. This detachable assembly structure also means that if a part of the structure is damaged, it can be replaced by disassembling the corresponding part. The operation is simple and convenient, and the maintenance cost is low. After assembly, the device forms a vertical ladder structure with a small top and a large bottom, so the device has high stability.

[0017] The device is designed with a structure that allows for stable lifting of the support, lifting components, and connecting plates after assembly. Furthermore, the overall operation is convenient, quick, and easy to use during assembly and disassembly. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1This invention further illustrates a specific embodiment of a combined bracket for maintaining the barrel, overcoming the shortcomings of existing brackets that only provide support and cannot meet the actual needs of barrel disassembly, assembly, and maintenance. The device employs a detachable installation structure, allowing for easy disassembly and storage of individual components. This detachable assembly structure also simplifies operation, allowing for easy replacement of damaged parts, resulting in low maintenance costs. Furthermore, the assembled device forms a vertical ladder structure with a smaller top and larger bottom, thus ensuring high stability. This invention is not limited to the embodiments described below.

[0024] Example 1:

[0025] This embodiment provides a combined bracket for maintaining the body tube, such as... Figure 1 As shown, the device includes a support 1, a lifting assembly 3, and a connecting plate 2. There are two supports 1, symmetrically distributed. A vertically movable tube clamp 4 is mounted on the top of each support 1. The lifting assembly 3 is located below the tube clamp 4 and controls its lifting and lowering. The connecting plate 2 is located below the supports 1 and connects the bottoms of the two supports 1. Both the lifting assembly 3 and the connecting plate 2 are detachably connected to the supports 1, forming a vertical ladder structure with a smaller top and a larger bottom. Because the device uses a detachable installation structure, each component can be disassembled for transportation and storage, facilitating both. This detachable assembly structure also allows for easy replacement of damaged parts, simplifying operation and reducing maintenance costs. Furthermore, the overall structure forms a vertical ladder structure with a smaller top and a larger bottom, resulting in high stability.

[0026] Working principle: This device is mainly used for the daily maintenance of tubular structures, such as gun barrels. When in use, the device is first assembled into a vertical ladder structure with a small top and a large bottom. Then, the tubular structure is placed on top of the two barrel holders 4. The height of the barrel holders 4 is adjusted by the lifting component 3 as needed to make the barrel height appropriate before the barrel is maintained.

[0027] Specifically, such as Figure 1 and Figure 3As shown, in order to achieve the detachable installation of the connecting plate 2, in this embodiment, the bracket 1 includes a main rod 11, an upper crossbar 13, and a lower crossbar 12. There are two main rods 11, which are symmetrical and inclined inward from bottom to top. The upper crossbar 13 is located above the two main rods 11, and the lower crossbar 12 is located below the two main rods 11. The upper ends of the lower crossbar 12 are provided with slots 120, and the lower ends of the connecting plate 2 are provided with U-shaped protrusions 20. The U-shaped protrusions 20 are engaged in the slots 120 and pinned by pins 121. This structure allows the connecting plate 2 to be disassembled from the bracket 1 simply by removing the pins 121 and moving the connecting plate 2 to separate it from the bracket 1, making the operation convenient and quick.

[0028] Example 2

[0029] Based on Example 1, such as Figures 1-4 As shown, to ensure the stability of the entire bracket after assembly and the effectiveness of the lifting component 3, in this embodiment, the lifting component 3 includes two jacks 30 connected by a connecting rod 31. The bottom of each jack 30 has a U-shaped base 33, and the middle of the upper crossbar 13 has a slot 131 that fits the U-shaped base 33. After the entire bracket is assembled, the U-shaped bases 33 at the bottom of the two jacks 30 are respectively located in the slots 131 in the middle of the two upper crossbars 13. This structural arrangement allows the entire bracket to connect the upper and lower parts of the two supports 1 through the cooperation of the lifting component 3 and the connecting plate 2 after assembly, thereby ensuring the stability of the entire bracket after assembly. The lifting component 3 not only lifts the body tube bracket 4, but also pulls and connects the upper parts of the two supports 1. This reduces the number of structures in the entire device, that is, no other connecting rod structure needs to be installed on the top, thus facilitating device assembly and reducing device cost.

[0030] Specifically, such as Figures 1-4 As shown, in order to enable the body tube holder 4 to be raised and lowered, in this embodiment, a guide shaft 14 is installed on the top of the main rod 11. The body tube holder 4 includes a holder 40 and a sleeve 41. The top of the holder 40 is provided with a circular groove structure that can fit the body tube. The sleeve 41 is set at both ends of the holder 40 and is respectively sleeved on the guide shaft 14 at the top of the two main rods 11. The bottom of the holder 40 contacts the top of the jack 30. When it is necessary to raise the height of the body tube holder 4, the body tube holder 4 can be lifted along the guide shaft 14 by the jack 30. When it is necessary to lower the height of the body tube holder 4, the body tube holder 4 can be lowered along the guide shaft 14 by releasing the jack 30.

[0031] Specifically, such as Figures 1-4As shown, in order to ensure that the jack 30 is relatively stable when lifting the body tube clamp 4, in this embodiment, the piston rod of the jack 30 is provided with a lifting plate 32 at the top, and the bottom of the clamp 40 is provided with a lifting clamp hole 402. The lifting plate 32 is engaged in the lifting clamp hole 402. The lifting clamp hole 402 and the lifting plate 32 are adapted to each other. Together with the U-shaped base 33 at the bottom of the jack 30, the overall stability of the entire lifting assembly 3 can be improved.

[0032] Specifically, such as Figures 1-4 As shown, in order to ensure the stability of the tube during the maintenance process, in this embodiment, a strap 42 is installed above the bracket 40. The strap 42 can be used to bind and fix the tube after it is erected to ensure its stability.

[0033] Specifically, such as Figures 1-4 As shown, in order to facilitate the binding and unbinding of the strap 42, in this embodiment, one end of the strap 42 is fixed to the upper opening of one end of the card holder 40, and the upper opening of the other end of the card holder 40 is provided with an insertion opening 400. A shaft 401 is provided in the insertion opening 400, and the strap 42 is provided with Velcro 420. When it is necessary to bind the body tube, the strap 42 is wrapped around the top of the body tube, then passed through the shaft 401 in the insertion opening 400, and then fixed by the Velcro 420. The operation is convenient and quick. Conversely, the Velcro 420 is torn off and one end of the strap 42 is pulled out.

[0034] Specifically, such as Figure 1 As shown, in order to facilitate the movement of the combined bracket, in this embodiment, the bottom of the bracket 1 is equipped with multiple casters 10 to assist the movement of the bracket.

[0035] Specifically, such as Figure 1-3 As shown, in order to facilitate the maintenance of the tube, in this embodiment, a tray 5 is also provided above the two supports 1. The tray 5 has tray shafts 50 on both sides and two upper crossbars 13 have insertion holes 130 that are adapted to the tray shafts 50. When the tray 5 is installed, the tray shafts 50 are inserted into the insertion holes 130. Maintenance and repair tools can be placed through the tray 5, thereby facilitating the maintenance of the tube.
