Description

Technical Field

[0001] This utility model relates to the field of roller frames, and in particular to a portable tool for replacing lower V-shaped roller frames. Background Technology

[0002] Belt conveyors are widely used continuous transportation equipment in mines, ports, power plants, and other places. The lower V-shaped roller frame in the frame is mainly used to install V-shaped idlers, which support and bear the load of the conveyor belt. The lower V-shaped roller frame is usually characterized by its stable structure, strong pressure resistance, and long service life. However, it can still rust, deform, or be damaged during long-term use, requiring regular inspection or replacement.

[0003] In existing technologies, dedicated replacement tools are usually placed directly on the ground for operation. However, this method has significant drawbacks. The supporting brackets are often rigid structures with a fixed height. When there are height differences between the lower V-shaped roller frames at different locations on the production line, the fixed brackets cannot be adjusted flexibly, which may result in the tools not being able to effectively connect with the roller frames, making disassembly operations impossible. A more common problem is that the workshop floor inevitably becomes uneven after long-term use. In this case, the rigid brackets do not make complete contact with the ground, resulting in poor overall stability and making them prone to shaking and overturning when force is applied. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable tool for replacing lower V-shaped roller frames, aiming to improve the problem that the fixed length of the support of the dedicated replacement tool cannot adapt to lower V-shaped roller frames of different heights.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable tool for replacing a lower V-shaped roller frame, comprising a support base, a shaft mounted on the top of the support base, a connecting ring sleeved on the shaft, a rotating handle fixedly connected to one end of the connecting ring, a U-shaped retaining ring connected to one end of the rotating handle, and multiple telescopic support legs equidistantly arranged on the bottom circumference of the support base; The telescopic support leg includes a column shell fixedly installed on the lower surface of the support base. A pull rod is provided inside the column shell. A fixing ring is fixedly installed on the surface of the column shell. A pin is provided on one side of the fixing ring. A spring is sleeved on the surface of the pin. One end of the spring is connected to the pin, and the other end of the spring is connected to the fixing ring. The telescopic support leg also includes a plurality of limiting holes equally spaced on the pull rod. The pin is inserted into the limiting holes.

[0006] According to the above technical solution: the telescopic support legs can be adjusted to accommodate lower V-shaped roller frames of different heights. Furthermore, in uneven ground conditions, the telescopic legs can be adjusted independently to ensure the equipment remains level, preventing tilting and instability caused by three points of support and one point of suspension. The insertion post structure makes rotating the handle easier. In addition, by inserting the posts into different holes, the application point or position of the downward pressure can be flexibly adjusted, allowing it to better adapt to different working scenarios and processing requirements.

[0007] Preferably, one end of the rotating handle has multiple insertion holes, and each insertion hole has a insertion post with a protrusion on its surface.

[0008] Preferably, a fixing block is installed on the upper surface of the support base, and the shaft is fixed between the fixing blocks by bolts.

[0009] Preferably, the sockets are equidistant, with a distance of approximately 10-15 cm between any two sockets.

[0010] Preferably, the bottom of the pull rod is provided with a pad, and the pad is cylindrical.

[0011] Preferably, the pull rod slides within the cylindrical shell, and both the surface of the pull rod and the inner wall of the cylindrical shell are smooth.

[0012] Preferably, one end of the connecting ring is provided with a connecting block, and the rotating handle is fixedly installed on the connecting block.

[0013] Preferably, one end of the pin passes through the retaining ring, the cylindrical shell, and the pull rod.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the length of the telescopic support leg can be adjusted to adapt to the lower V-shaped roller frame of different heights. At the same time, in the case of uneven ground, the telescopic leg can be adjusted independently to ensure that the equipment as a whole remains horizontal, avoiding the tilting and instability of the equipment caused by three points of support and one point of suspension.

[0015] 2. In this utility model, by setting the insert structure, it is easier to rotate the handle. In addition, by inserting the insert into different holes, the point of application of force or the position of action can be flexibly adjusted so that it can better adapt to different working scenarios.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a portable tool for replacing the lower V-shaped roller frame, including a support base 1, a shaft 2 installed above the support base 1, a connecting ring 3 sleeved on the shaft 2, a rotating handle 4 fixedly connected to one end of the connecting ring 3, a U-shaped retaining ring 5 connected to one end of the rotating handle 4, and multiple telescopic support legs 6 equidistantly arranged around the bottom circumference of the support base 1. The telescopic support leg 6 includes a column shell 601 fixedly installed on the lower surface of the support base 1. A pull rod 602 is provided inside the column shell 601. A fixing ring 603 is fixedly installed on the surface of the column shell 601. A pin 604 is provided on one side of the fixing ring 603. A spring 605 is sleeved on the surface of the pin 604. One end of the spring 605 is connected to the pin 604, and the other end of the spring 605 is connected to the fixing ring 603. The telescopic support leg 6 also includes a plurality of limiting holes 606 equidistantly opened on the pull rod 602. The pin 604 is inserted into the limiting holes 606.

[0020] Specifically, through the telescopic support leg 6 structure, operators can flexibly adjust the length of each support leg according to different working conditions to adapt to the installation requirements of lower V-shaped roller frames at various heights. Furthermore, when encountering uneven ground, the telescopic support leg 6 can independently adjust its length, ensuring that each support point is in full contact with the ground. This ensures the equipment remains level, solving the problem of one point being suspended in traditional three-point support structures, enhancing the stability and safety of the equipment, preventing tilting or vibration caused by unstable support, and guaranteeing a smooth operation.

[0021] Reference Figure 3 and Figure 4 The rotating handle 4 has multiple insertion holes 7 at one end, and each insertion hole 7 has a insertion post 8 inside. The surface of the insertion hole 7 has a protrusion. The upper surface of the support base 1 is equipped with a fixing block, and the shaft 2 is fixed between the fixing blocks by bolts. The insertion holes 7 are equidistant, and the distance between any two insertion holes 7 is about 10~15cm.

[0022] Specifically, the protrusions on the surface of the insert 8 increase the friction between it and the palm, effectively preventing slippage and loss of hand during pressing, and ensuring smooth and stable operation.

[0023] Reference Figure 2 and Figure 3 The bottom of the pull rod 602 is equipped with a pad 9, which is cylindrical.

[0024] Specifically, to prevent the telescopic support leg 6 from damaging the ground when the equipment lifts the lower V-shaped roller frame, the equipment is equipped with pads 9, which are made of soft material and provide effective protection.

[0025] Reference Figure 1 and Figure 3 The pull rod 602 slides inside the column housing 601, and the surface of the pull rod 602 and the inner wall of the column housing 601 are both smooth; one end of the connecting ring 3 is provided with a connecting block, and the rotating handle 4 is fixedly installed on the connecting block; one end of the pin 604 passes through the fixing ring 603, the column housing 601 and the pull rod 602.

[0026] Specifically, the surface of the pull rod 602 and the inner wall of the column housing 601 are both smoothly designed, which effectively reduces the friction between them, making the pull rod 602 slide more smoothly and extending the service life of the parts.

[0027] Working principle: During operation, the telescopic support leg 6 is adjusted to accommodate lower V-shaped roller frames of different heights. During adjustment, the pin 604 is pulled out, at which point the spring 605 deforms, pulling the lever 602. When the lever is adjusted to the appropriate position, the pin 604 is released, and the spring 605 rebounds, inserting the pin 604 into the limiting hole 606 to fix the lever 602, thereby fixing the telescopic support leg 6 as a whole. Then, the rotating handle 4 is rotated to engage the U-shaped retaining ring 5 with the cross brace structure of the lower V-shaped roller frame to be replaced, achieving initial fixation. Then, the U-shaped retaining ring 5 is rotated to lift the cross brace structure of the lower V-shaped roller frame. When rotating the rotating handle 4, the insert pin 8 can be adjusted to be inserted into the insert hole 7 at different positions, making it easier to rotate the handle 4. In addition, by inserting the insert pin 8 into the insert hole 7 at different positions, the application point or position of the downward pressure can be flexibly adjusted to better adapt to different working scenarios.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
