Description

Technical Field

[0001] This application relates to the field of maintenance equipment, and more specifically, to a wheel replacement support fixture. Background Technology

[0002] As a vital economic sector in my country, the tobacco industry's automation level and technological quality directly impact the market competitiveness of its products. Storage cabinets, key equipment in cigarette manufacturing workshops, are primarily used for storing tobacco leaves, stems, and shredded tobacco, playing an irreplaceable role in balancing production, moistening tobacco leaves, and uniformly distributing moisture. With the continuous development of tobacco machinery technology, modern storage cabinet equipment features compact structures and high levels of automation, significantly contributing to improving tobacco product quality, promoting technological progress, and enhancing economic efficiency.

[0003] As a core component of the storage tank system, the operating status of the material spreading trolley directly affects the working efficiency and material spreading uniformity of the storage tank. The material spreading trolley achieves uniform material spreading through the reciprocating motion of its wheels on tracks. This operating mode causes the wheels to bear significant dynamic loads over long periods. In actual production, due to continuous operation, material impact, and environmental factors, the wheels commonly experience wear, aging, and even breakage. Statistics show that a medium-sized cigarette factory's tobacco processing workshop typically has about 80 storage tank units, requiring a considerable number of wheel replacements annually.

[0004] Currently, the industry lacks specialized tooling and equipment for replacing fabric carriage wheels, and maintenance personnel typically use traditional manual methods. This method is not only time-consuming and labor-intensive, usually requiring 3-4 operators working together, but also prone to parts shifting and falling during the skid-mounting process. More seriously, the temporary padding tools may shift, posing a safety hazard of the carriage wheel falling and injuring personnel or damaging equipment. These problems not only increase maintenance costs but also affect the normal operating efficiency of the production line.

[0005] Therefore, there is an urgent need to provide a wheel replacement support fixture to solve the above problems. Utility Model Content

[0006] The purpose of this application is to provide a wheel replacement support fixture, which can solve to some extent the problem that the wheel replacement of the storage container fabrication vehicle currently requires manual operation, and at the same time, it is necessary to find other structures to pry up the vehicle body, which not only has poor stability, but also requires a large number of personnel and has low work efficiency.

[0007] The wheel replacement support fixture provided in this application is used for replacing the wheels of a storage tank fabrication vehicle. It includes a lifting component, a support pipe, and a lifting component. The telescopic end of the lifting component is connected to one end of the support pipe, and the other end of the support pipe is connected to the lifting component. The lifting component forms a lifting space for positioning the support crossbar of the storage tank fabrication vehicle.

[0008] The wheel replacement support fixture provided by this utility model also includes a positioning plate, and the base of the lifting component is connected to the positioning plate.

[0009] Specifically, the lifting component is a jack, the telescopic end of the jack has a first threaded portion, the inner diameter of the support tube is adapted to the diameter of the telescopic end of the jack, and the inner wall of the support tube has a second threaded portion. The first threaded portion and the second threaded portion are threadedly engaged, so that the support tube and the jack can be detachably connected.

[0010] Furthermore, a connecting hole is formed at the end of the support tube away from the lifting member. The lifting member includes a lifting part and a connecting part. The connecting part is connected to the connecting hole, so that the lifting part and the support tube are detachably connected.

[0011] The wheel replacement support fixture provided by this utility model also includes a traveling wheel assembly, which includes a wheel body and a mounting base. One end of the mounting base is connected to the edge of the positioning plate and is set at an angle to the positioning plate. The wheel body is rotatably connected to the mounting base. When the positioning plate contacts the positioning surface, the wheel body tilts up relative to the positioning surface, so that a set gap is formed between the wheel body and the positioning surface.

[0012] Specifically, there are at least two mounting seats, and the mounting seats are spaced apart, with the number of wheels corresponding to the number of mounting seats.

[0013] Furthermore, the positioning plate is rectangular, and the four sides of the positioning plate are connected to the walking wheel assembly.

[0014] Furthermore, the wheel replacement support fixture provided by this utility model also includes an auxiliary support mechanism; one end of the auxiliary support mechanism is rotatably connected to the support tube, and the auxiliary support mechanism is set against the outer wall of the support tube in the retracted state, and in the supported state, the other end of the auxiliary support mechanism abuts against the positioning surface.

[0015] Furthermore, there are multiple auxiliary support mechanisms, and these multiple auxiliary support mechanisms are evenly distributed along the circumference of the support tube.

[0016] Furthermore, the auxiliary support mechanism includes a first connecting seat, a second connecting seat, a support rod, and a support plate; the first connecting seat is connected to the support tube, one end of the support rod is rotatably connected to the first connecting seat, the second connecting seat is disposed on the support plate, and the other end of the support rod is rotatably connected to the second connecting seat.

[0017] Compared with existing technologies, the wheel replacement support fixture provided in this application has the following advantages: The wheel replacement support fixture provided in this application is used for replacing the wheels of a storage tank fabrication vehicle. It includes a lifting component, a support pipe, and a lifting component. The telescopic end of the lifting component is connected to one end of the support pipe, and the other end of the support pipe is connected to the lifting component. The lifting component forms a lifting space for positioning the support crossbar of the storage tank fabrication vehicle.

[0018] Analysis reveals that, since the fabric carrier needs to travel on the track and is some distance from the positioning surface, the lifting distance of the jacking component is limited and cannot smoothly support the fabric carrier. Therefore, by connecting the support pipe to the telescopic end of the jacking component, when the jacking component is placed on the positioning surface, the telescopic end can be extended through the support pipe. Furthermore, the lifting component in this application is connected to the other end of the support rod, and the lifting component forms a lifting space, which can position the support crossbar. Thus, during operation, the tooling is first placed at the position where the wheel to be replaced needs to be. Then, the telescopic end of the jacking component lifts and pushes the support pipe upward, causing the lifting component to move towards the support crossbar until the support crossbar enters the positioning space. Through further lifting of the jacking component, the support crossbar can be lifted by the lifting component, allowing the wheel at the corresponding position of the fabric carrier to gradually derail, thereby enabling wheel replacement.

[0019] Because the replacement fixture provided in this application remains supported and in a fixed position throughout the wheel replacement process, there will be no movement of the fixture as long as the concrete placing vehicle is stationary, thus ensuring the stability and safety of the wheel maintenance process. Furthermore, it eliminates the need for multiple people to work together, significantly reducing labor costs. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for 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 application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] like Figure 1 As shown, the wheel replacement support fixture provided in this application is used for replacing the wheels of the storage container fabrication vehicle. It includes a lifting component 2, a support pipe 3, and a lifting component 4. The telescopic end of the lifting component 2 is connected to one end of the support pipe 3, and the other end of the support pipe 3 is connected to the lifting component 4. The lifting component 4 forms a lifting space for positioning the support crossbar of the storage container fabrication vehicle.

[0027] Compared with existing technologies, the wheel replacement support fixture provided in this application has the following advantages: Since the fabric carrier needs to travel on the track and is some distance from the positioning surface, the lifting distance of the lifting member 2 is limited and cannot smoothly support the fabric carrier. Therefore, by connecting the support pipe 3 to the telescopic end of the lifting member 2, when the lifting member 2 is placed on the positioning surface, the telescopic end can be extended through the support pipe 3. Furthermore, the lifting member 4 in this application is connected to the other end of the support rod 7, and the lifting member 4 forms a lifting space, which can position the support crossbar. Thus, during operation, the tooling is first placed at the position where the wheel to be replaced needs to be placed. Then, the telescopic end of the lifting member 2 is lifted to push the support pipe 3 upward, driving the lifting member 4 to move towards the support crossbar until the support crossbar enters the positioning space. Through further lifting of the lifting member 2, the support crossbar can be lifted by the lifting member 4, allowing the wheel at the corresponding position of the fabric carrier to gradually derail, thereby enabling wheel replacement.

[0028] Because the replacement fixture provided in this application remains supported and in a fixed position throughout the wheel replacement process, there will be no movement of the fixture as long as the concrete placing vehicle is stationary, thus ensuring the stability and safety of the wheel maintenance process. Furthermore, it eliminates the need for multiple people to work together, significantly reducing labor costs.

[0029] Optionally, such as Figure 1 As shown, the wheel replacement support tool provided by this utility model also includes a positioning plate 1, and the base of the lifting component 2 is connected to the positioning plate 1.

[0030] Since the tooling provided in this application is mainly for replacing the wheels of the storage container material carrier, and the material of the positioning surface of the tooling is usually not a solid cement or metal ground, but a base strip made of PVC polyvinyl chloride and other materials, this application can increase the contact area between the overall tooling and the positioning surface by further setting the positioning plate 1 and setting the lifting component 2 on the positioning plate 1.

[0031] It is understandable that, due to the limited size of the base of the lifting component 2 and the small contact area with the bottom strip, the bottom strip is easily damaged due to stress concentration during operation. Once the bottom strip is damaged, it will take a lot of time and money to repair it. Therefore, this application can increase the contact area between the lifting component 2 and the bottom strip by further setting the positioning plate 1, thereby dispersing the stress during the support process and reducing the risk of damaging the bottom strip during support to a certain extent.

[0032] The positioning plate 1 in this application is made of metal material, preferably aluminum plate, which is lightweight and strong. Reducing the overall weight of the tooling makes it easier to handle during transportation.

[0033] More preferably, the positioning plate 1 in this application is 5mm thick and is a rectangular plate with a length and width of 400mm*250mm.

[0034] Optionally, such as Figure 1 As shown, the lifting component 2 in this application is a jack. The telescopic end of the jack has a first threaded portion. The inner diameter of the support tube 3 is adapted to the diameter of the telescopic end of the jack, and the inner wall of the support tube 3 has a second threaded portion. The first threaded portion and the second threaded portion are threadedly engaged, so that the support tube 3 and the jack can be detachably connected.

[0035] By forming a first threaded portion at the telescopic end of the jack and a second threaded portion at one end of the support tube 3, a detachable connection between the support tube 3 and the jack can be achieved. This allows for the selection of different lengths of the support tube 3 according to different support conditions. Preferably, there can be multiple support tubes 3 in this application with different lengths, so that a suitable size of support tube 3 can be selected according to specific operational requirements. This avoids the problem that the supporting member 4 cannot smoothly support the support crossbar due to a short support tube 3 or that the overall tooling cannot smoothly enter the support position due to a long support tube 3.

[0036] Meanwhile, the detachable support tube 3 can be repaired or replaced in a timely manner, avoiding breakage during operation due to damage to the support tube 3, which could affect the safety of the workers.

[0037] It is understood that the diameter of the support tube 3 in this application is larger than the diameter of the telescopic end of the jack, so that it can be fitted onto the telescopic end of the jack.

[0038] In this application, the support tube 3 has a diameter of 80 mm, a length of 800 mm, and a wall thickness of 3 mm. Based on this, an alloy steel block can be welded 50mm deep inside the support tube 3, and the aforementioned second threaded part can be formed on the alloy steel block, thereby further strengthening the strength of the connection of the support tube 3.

[0039] It should be noted that in some embodiments, the support tube 3 and the lifting member 4 are connected by welding to ensure the connection strength and stability of the two.

[0040] In some embodiments, the end of the support tube 3 away from the lifting member 4 in this application is formed with a connecting hole. The lifting member 4 includes a lifting part and a connecting part. The connecting part is connected to the connecting hole, so that the lifting part and the support tube 3 are detachably connected.

[0041] The connecting hole in this application is a screw hole, and the connecting part is a screw rod. The detachable connection between the lifting component 4 and the support tube 3 is achieved through the threaded connection. Since both the support tube 3 and the lifting component 4 are detachable in this application, the maintenance and replacement cost is lower, and the transportation process is also easier.

[0042] Furthermore, in some operations, since the lifting component 2 is already positioned, the rotating lifting component 4 can be used to smoothly align with the support crossbar without adjusting the overall tooling angle, thus improving work efficiency to a certain extent.

[0043] It should be noted that the supporting component 4 in this application is U-shaped, with a width of 80mm, a length of 120mm, and a height of 80mm.

[0044] Optionally, such as Figure 1 As shown, the wheel replacement support fixture provided by this utility model also includes a traveling wheel assembly. The traveling wheel assembly includes a wheel body 6 and a mounting seat 5. One end of the mounting seat 5 is connected to the edge of the positioning plate 1 and is set at an angle to the positioning plate 1. The wheel body 6 is rotatably connected to the mounting seat 5. When the positioning plate 1 contacts the positioning surface, the wheel body 6 tilts up relative to the positioning surface, so that a setting gap is formed between the wheel body 6 and the positioning surface.

[0045] Since the jack has a certain weight, it is quite laborious to carry it manually over long distances. Therefore, this application further provides a walking wheel assembly at the edge of the positioning plate 1, which makes it easier for manual handling.

[0046] Due to the special nature of the positioning surface of the tooling provided in this application, if the positioning plate 1 is placed on the traveling wheel assembly, meaning the traveling wheel assembly is always in contact with the positioning surface, the stress will be more concentrated, leading to damage to the positioning surface. Therefore, this application provides a mounting seat 5 on the positioning plate 1, and the mounting seat 5 is set at an angle to the positioning plate 1, so that after the wheel body 6 is connected to the mounting seat 5, it is in a tilted state relative to the positioning surface. That is, when the positioning plate 1 is in contact with the positioning surface, the wheel body 6 is separated from the positioning surface.

[0047] When the work is completed and needs to be transferred, the operator can hold the lifting component 4 and tilt the entire tooling so that the wheel 6 contacts the positioning surface. Since there is no load at this time, the tooling only exerts pressure on the positioning surface due to the weight of the entire tooling. Therefore, there will be no problem of damage to the positioning surface, which makes the transfer process more labor-saving.

[0048] Preferably, the wheel 6 in this application is a swivel wheel, and the wheel 6 is a flexible wheel 6, so as to avoid damage to the positioning surface during the transfer process.

[0049] More preferably, there are at least two mounting seats 5 in this application, and the mounting seats 5 are spaced apart, with the number of wheels 6 corresponding to the number of mounting seats 5.

[0050] The term "at least two mounting seats 5" refers to the fact that at least two mounting seats 5 are provided on one side of the positioning plate 1, so that two wheels 6 can be installed, thereby making the movement process more stable.

[0051] like Figure 1 As shown, since the positioning plate 1 in this application is rectangular, optionally, all four sides of the positioning plate 1 in this application are connected to a walking wheel assembly.

[0052] By setting walking wheel assemblies on all four sides of the positioning plate 1, the entire tooling can be quickly moved after the work is completed without adjusting the direction, making the movement process smoother.

[0053] Optionally, such as Figure 1 As shown, the wheel replacement support tool provided by this utility model also includes an auxiliary support mechanism; one end of the auxiliary support mechanism is rotatably connected to the support tube 3, and the auxiliary support mechanism is set against the outer wall of the support tube 3 in the retracted state, and in the supported state, the other end of the auxiliary support mechanism abuts against the positioning surface.

[0054] This application provides an auxiliary support mechanism on the support tube 3. When working, the auxiliary support mechanism is rotated to move away from the support tube 3, so that the other end of the auxiliary support mechanism can abut against the positioning surface, thereby forming a triangular support structure and improving support stability.

[0055] Optionally, such as Figure 1 As shown, there are multiple auxiliary support mechanisms in this application, and the multiple auxiliary support mechanisms are evenly distributed along the circumference of the support tube 3.

[0056] The stability of the support can be further improved by setting multiple auxiliary support mechanisms. Preferably, in this embodiment, the support pipe 3 can be made of square steel, which has higher strength and can also provide a flat surface for the installation of the auxiliary support mechanisms.

[0057] Optionally, such as Figure 1 As shown, the auxiliary support mechanism in this application includes a first connecting seat 9, a second connecting seat 10, a support rod 7, and a support plate 8; the first connecting seat 9 is connected to the support tube 3, one end of the support rod 7 is rotatably connected to the first connecting seat 9, the second connecting seat 10 is disposed on the support plate 8, and the other end of the support rod 7 is rotatably connected to the second connecting seat 10.

[0058] In this application, both the first connecting seat 9 and the second connecting seat 10 are connecting lugs, and the support rod 7 and the support tube 3, as well as the support rod 7 and the support plate 8, can be rotatably connected by a pivot structure such as a pin.

[0059] Understandably, when not in operation, the support rod 7 is rotated to a state parallel to the support tube 3, that is, the support rod 7 is set against the outer wall of the support tube 3. When in operation, the support rod 7 is rotated, and the support plate 8 is rotated at the same time, so that both the support plate 8 and the positioning plate 1 are in contact with the positioning surface. This can further increase the contact area between the overall tooling and the positioning surface, and can form a triangular support structure, thereby improving the support stability of the overall tooling.

[0060] In this embodiment, the support tube 3 is made of square steel, thus having four mounting surfaces. However, since the support plate 8 has a certain size, auxiliary support mechanisms can be installed on two opposite surfaces of the support tube 3 to avoid interference in the retracted state, thereby supporting the overall tooling. Alternatively, auxiliary support mechanisms can be installed on all four surfaces. When four auxiliary support mechanisms are installed, the lengths of the support rods 7 are different, allowing two of the support plates 8 to be positioned at different horizontal heights with the other two support plates 8. This avoids interference between the four support plates 8, ensures the retracted state of the auxiliary support mechanisms, and prevents any impact on the operators during transport.

[0061] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
