[0019] This utility model provides, for example Figures 1-5 The invention described is a lightweight, manually operated hydraulic temporary support that can effectively hug the support, comprising a support body 1 and a hugging component 2 for lifting the support body 1. The overall design balances portability with the stability of the hugging component.

[0020] The circling component 2, as the core circling structure, adopts a cross-shaped design, specifically including a first swing plate 201 and a second swing plate 202. A shaft 204 is fixedly installed at the middle section of the first swing plate 201, and the second swing plate 202 can rotate around the shaft 204. This rotating connection structure allows the first swing plate 201 and the second swing plate 202 to flexibly adjust their opening and closing angles according to the outer diameter of the support body 1, adapting to support bodies 1 with different outer diameter specifications.

[0021] The first swing plate 201 and the second swing plate 202 are both made of 6061-T6 aluminum alloy, which is lightweight and easy for operators to handle.

[0022] At the bottom of the first swing plate 201 and the second swing plate 202, a support plate 203 is integrally formed. The inner sidewall of the support plate 203 is provided with wear-resistant rubber pads to reduce wear. The two support plates 203 are naturally distributed in a V shape, which can provide initial support and limit the support body 1 from both sides, preventing the support body 1 from slipping during the lifting process. It is also suitable for support bodies 1 with different outer diameter specifications.

[0023] Considering that the support body 1 in mine construction has various length specifications (such as conventional models such as 1.2m, 1.5m, 1.8m, etc.), this utility model achieves adjustable distance between the two clasping parts 2 through an adjustment component. This ensures that no matter how the length of the support body 1 changes, the two clasping parts 2 can always accurately correspond to the two ends of the support body 1, avoiding lifting imbalance caused by improper spacing. The adjustment component specifically consists of a sliding rod 3, a sliding cylinder 4, a threaded rod 5, and a threaded cylinder 6. Two threaded rods 5 are provided. The sliding rod 3 and the sliding cylinder 4 are respectively welded and fixed to the two first swing plates 201 close to each other. On one end face, the outer diameter of the slide rod 3 is matched with the inner diameter of the slide cylinder 4. The two ends close to each other can achieve a smooth sliding fit, which can not only provide guidance for the adjustment of the distance between the two ring parts 2, but also ensure the structural stability during the adjustment process. The two threaded rods 5 are respectively fixedly connected to the two second swing plates 202 close to each other. The inner walls of both ends of the threaded cylinder 6 are machined with internal threads with opposite directions, which are threadedly connected to the two threaded rods 5 respectively. By rotating the threaded cylinder 6, the two threaded rods 5 can be driven to move towards or away from each other, thereby driving the two ring parts 2 to clamp or loosen the support body 1.

[0024] To facilitate manual rotation of the threaded cylinder 6, a rotating sleeve 7 is welded and fixed to the outside of the threaded cylinder 6. The outer wall of the rotating sleeve 7 is machined with anti-slip texture to increase the friction between the hand and the rotating sleeve 7, reduce the difficulty of rotation operation, and can be easily operated even in the humid and dusty environment of the mine.

[0025] When adjusting the distance between the two retaining members 2, the operator holds the rotating sleeve 7 and rotates it clockwise or counterclockwise, causing the threaded cylinder 6 to rotate synchronously. If rotated clockwise, the two threaded rods 5 move towards each other, causing the two retaining members 2 to move closer together, reducing the distance; if rotated counterclockwise, the two threaded rods 5 move away from each other, causing the two retaining members 2 to move further apart, increasing the distance. The entire adjustment process requires no additional tools and can be completed manually by a single person. It is convenient to operate and fully compatible with the length specifications of the main support body 1 commonly used in current mine construction.

[0026] Align the two circumferential members 2 with the adjusted spacing to the two ends of the support body 1, and make sure there is a gap between the bottom ends of the two support plates 203 for the support body 1 to pass through. Then, make the support plates 203 at the bottom ends of the first swing plate 201 and the second swing plate 202 in each circumferential member 2 abut against the ground.

[0027] Control the sliding cylinder 4 and the rotating sleeve 7 to move towards each other, and the two support plates 203 move closer to each other until the bottom ends of the two support plates 203 are close together and the support plates 203 are tightly attached to the outer wall of the support body 1, forming a stable support and limit.

[0028] The operator simultaneously holds the slide cylinder 4 and the rotating sleeve 7, and slowly applies a uniform upward pulling force. By adjusting the components, the support body 1 is lifted in a horizontal state under the stable support of the two circling parts 2.

[0029] If it is necessary to lower the support body 1, control the slide 4 and rotating sleeve 7 to move in opposite directions.

[0030] In actual use, a buckle or other structure is set between the slide cylinder 4 and the rotating sleeve 7. After the support plate 203 is tightly attached to the outer wall of the support body 1, the distance between the slide cylinder 4 and the rotating sleeve 7 is locked to prevent separation and ensure the stability of lifting. The adjustment is made according to the specific use.

[0031] In summary, this utility model, through the setting of the slide cylinder 4, adjustment components and other structures, is easy to operate, requires no additional tools, and is compatible with different support bodies 1. Furthermore, the adjustment components are used to complete the spacing adjustment and lifting, thereby improving the utilization efficiency of the hydraulic temporary support.

[0032] To further enhance the stability of the enclosure, ear seats 8 are welded and fixed on the side of the first swing plate 201 and the second swing plate 202 that are close to each other and near the support plate 203. A connecting plate 9 is rotatably connected to the ear seat 8 via a pin. A transmission plate 10 is set between the ends of the two connecting plates 9 away from the ear seats 8. The two ends of the transmission plate 10 are rotatably connected to the two connecting plates 9 via pins, forming a linkage structure of "ear seat 8-connecting plate 9-transmission plate 10". An elastic telescopic rod 11 is fixedly connected to the transmission plate 10. The elastic telescopic rod 11 has sufficient elastic force and reset ability. A pressure frame 12 is fixedly connected to the end of the elastic telescopic rod 11 away from the transmission plate 10. The pressure frame 12 is V-shaped, and the side of the pressure frame 12 near the support plate 203 is a concave side. A 3-5mm thick anti-slip rubber pad is pasted on the concave side. The surface of the rubber pad is processed with diamond-shaped anti-slip texture to further increase the friction with the support body 1.

[0033] When the two support plates 203 approach each other, the ear seat 8 pulls the connecting plate 9 to swing, thereby pushing the transmission plate 10 to move towards the support body 1. The operator can assist in applying force by gently holding the transmission plate 10 or the elastic telescopic rod 11 to guide the transmission plate 10 to move smoothly. During the movement of the transmission plate 10, it will drive the elastic telescopic rod 11 and the pressure frame 12 to move synchronously towards the support body 1 until the concave side of the pressure frame 12 abuts against the outer wall of the support body 1.

[0034] As the support plate 203 continues to approach, the elastic telescopic rod 11 is compressed by the reaction force of the support body 1, and its restoring elasticity makes the pressure frame 12 fit tightly against the support body 1. At this time, the pressure frame 12 presses the support body 1 from the top, and the two support plates 203 support the support body 1 from below, forming an effective all-round encircling structure.

[0035] Meanwhile, for the support body 1 with a smaller outer diameter, the elastic telescopic rod 11 has a smaller retraction distance, and the pressure frame 12 can fit tightly against the outer wall of the support under the action of the spring. For the support body 1 with a larger outer diameter, the elastic telescopic rod 11 has a larger retraction distance, and can still maintain the fit between the pressure frame 12 and the support through its own elasticity. It can adapt to support bodies 1 with different outer diameter specifications without additional adjustment, further improving the versatility and adaptability of the device.

[0036] In summary, this utility model forms an all-around effective encircling structure by setting up elastic telescopic rods 11, pressure frames 12 and other structures, and can be adapted to support body 1 with different outer diameter specifications, ensuring the stability of temporary support use.
