DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 As shown, a compact lifting equipment for base station construction includes a frame 1, a support frame 2 is rotatably connected to the front and rear side bosses on the upper side of the frame 1 near the right side, four rectangularly distributed universal wheels 3 are rotatably connected to the lower side of the frame 1 near the four corners, a push handle 4 is rotatably connected to the middle part of the upper side of the frame 1 near the left side, two front-to-back symmetrical supporting mechanisms 5 are rotatably connected to the front and rear sides of the support frame 2 near the upper side, and a lifting mechanism 6 is rotatably connected to the inner side of the frame 1.

[0025] It should be noted that a fixing component is provided at the rotation position of the push handle 4, which can limit the rotation of the push handle 4 as needed. The push handle 4 is used to push the entire body to move.

[0026] like Figure 1-Figure 3 As shown, the support mechanism 5 includes a support rod 51, the upper end of the support rod 51 is rotatably connected to the front and rear sides of the support frame 2 near the upper surface, the inner side of the support rod 51 is movably sleeved with an extension rod 52, and a side wall of the support rod 51 away from the support frame 2 is provided with a plurality of annularly distributed mounting grooves 53, and the inner sides of the plurality of mounting grooves 53 are movably sleeved with balls 54, and an outer wall of the support rod 51 away from the support frame 2 is threadedly connected with a rotating sleeve 55, and the ball 54 is located on the inner side of the rotating sleeve 55, and the side of the ball 54 away from the rotating sleeve 55 is movably sleeved in a groove opened on the outer wall of the extension rod 52 near the support frame 2.

[0027] It should be noted that the rotating sleeve 55 restricts the ball 54, making it unable to move, so that the ball 54 is stuck on the extension rod 52. The extension rod 52 is fixed, and the rotating sleeve 55 is rotated to make the ball 54 detach from the inner side of the rotating sleeve 55, so that the ball 54 can move, so that the extension rod 52 can slide freely on the inner side of the support rod 51.

[0028] like Figure 2 , Figure 3 As shown, the inner wall of the support rod 51 is provided with four annularly distributed limiting grooves 56 , and the outer wall of the extension rod 52 close to the support frame 2 is fixedly connected with four annularly distributed sliding blocks, and the sliding blocks are slidably connected to the inner side of the limiting grooves 56 .

[0029] It should be noted that the limiting groove 56 is used to limit the extension rod 52 so that the extension rod 52 cannot rotate relative to the support rod 51 , thereby preventing the groove on the extension rod 52 from being difficult to align with the ball 54 .

[0030] like Figure 1 , Figure 3 As shown, a fixing screw 57 is fixedly connected to the left side surface of the upper side of the frame 1 near the right boss and the left side of the upper surface of the frame 1 near the front and rear edges, and a threaded sleeve 58 is threadedly connected to the side of the outer wall of the extension rod 52 away from the support frame 2, and the outer wall of the fixing screw 57 on the left side is threadedly connected to the inner side of the threaded sleeve 58.

[0031] It should be noted that when the left-side fixing screw 57 is threadedly connected to the inner side of the threaded sleeve 58, the left-side fixing screw 57 fixes the extension rod 52, so that the extension rod 52 and the support rod 51 support the support frame 2, so that the support frame 2 cannot rotate, and the threaded sleeve 58 is rotated to cause the left-side fixing screw 57 to disengage from the threaded sleeve 58, so that the support frame 2 can rotate. When the support frame 2 is placed horizontally, the threaded sleeve 58 is rotated to cause the right-side fixing screw 57 to be movably sleeved on the inner side of the threaded sleeve 58, so that the extension rod 52 is fixed again, so that the support frame 2 cannot rotate.

[0032] like Figure 4 As shown, the lifting mechanism 6 includes a motor 61, the rear side of the motor 61 is fixedly connected to the boss on the upper surface of the support frame 2 near the front side, the output end of the motor 61 is fixedly connected to a screw rod 62, and two screw rods 62 are symmetrically distributed on the front and rear walls of the support frame 2, the outer wall of the screw rod 62 is threadedly connected to a mounting frame 63, and the middle part of the lower side of the mounting frame 63 is fixedly connected with four annularly distributed hooks 64 through a chain.

[0033] It should be noted that the motor 61 drives the screw rod 62 located on the right side to rotate, and when the screw rod 62 rotates, it drives the mounting frame 63 to move up and down. The hook 64 is used to hang on the hook portion on the manhole cover, so that when the mounting frame 63 moves up and down, it can drive the manhole cover to move up and down.

[0034] like Figure 4 , Figure 5 As shown, sprocket wheels 65 are fixedly connected to the outer walls of the two screw rods 62 near the upper ends, and the outer sides of the sprocket wheels 65 are meshedly connected to the chains 66 .

[0035] It should be noted that when the screw rod 62 on the right side rotates, it drives the sprocket 65 on the front side to rotate. Relying on the chain 66, the two sprockets 65 rotate synchronously in the same direction, causing the two screw rods 62 to rotate synchronously in the same direction, so that the front and rear sides of the mounting frame 63 are subjected to balanced force.

[0036] The working principle of the utility model is as follows: first, the rotating sleeve 55 restricts the ball 54, so that the ball 54 cannot move, so that the ball 54 is stuck on the extension rod 52. As a result, the extension rod 52 is fixed, and the rotating sleeve 55 is rotated to make the ball 54 disengage from the inner side of the rotating sleeve 55, so that the ball 54 can move, so that the extension rod 52 can slide freely inside the support rod 51, and the limiting groove 56 is used to restrict the extension rod 52, so that the extension rod 52 cannot rotate relative to the support rod 51, so as to avoid the groove on the extension rod 52 from being difficult to align with the ball 54. When the fixed screw 57 on the left side is threadedly connected to the threaded sleeve 5 8, the left fixing screw 57 fixes the extension rod 52, so that the extension rod 52 and the support rod 51 support the support frame 2, so that the support frame 2 cannot rotate, and the threaded sleeve 58 is rotated to cause the left fixing screw 57 to disengage from the threaded sleeve 58, so that the support frame 2 can rotate. When the support frame 2 is placed horizontally, the threaded sleeve 58 is rotated so that the right fixing screw 57 is movably sleeved on the inner side of the threaded sleeve 58, so that the extension rod 52 is fixed again, so that the support frame 2 cannot rotate. The support of the support rod 51 and the extension rod 52 makes the support frame 2 stable, and the threaded sleeve 58 is rotated so that the threaded sleeve The sleeve 58 is disengaged from the fixed screw 57 on the left side, and then the rotating sleeve 55 is rotated to close the extension rod 52, so that the support frame 2 can be rotated, and then the threaded sleeve 58 is rotated to make the fixed screw 57 on the right side enter the inner side of the threaded sleeve 58 to fix the support frame 2, and finally the push handle 4 is rotated to make the push handle 4 fall down, so that the whole is in a storage state, reducing the occupied space and facilitating storage and transportation. Finally, the motor 61 drives the screw rod 62 on the right side to rotate, and when the screw rod 62 rotates, it drives the mounting frame 63 to move up and down, and the hook 64 is used to hang on the part for hooking on the manhole cover, so that the mounting frame 6 When the manhole cover moves up and down, the screw rod 62 on the right side rotates, which drives the sprocket 65 on the front side to rotate. By relying on the chain 66, the two sprockets 65 rotate synchronously in the same direction, which causes the two screw rods 62 to rotate synchronously in the same direction, so that the front and rear sides of the mounting frame 63 are balanced in force. The manhole cover is hung by the hook 64, and the motor 61 drives the screw rod 62 to rotate, so that the manhole cover is lifted, which is convenient for the transportation of the manhole cover. The screw rod 62 is used to lift it, which avoids the problem of the manhole cover shaking due to the influence of the flexible component during transportation caused by the original method of the traction rope-like component.
