Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of luffing trolley processing, and more specifically, to a tower crane luffing trolley machining tool. Background Art
[0002] Tower crane is the most commonly used lifting equipment on construction sites. It is connected to a standard section by section to lift the raw materials for construction such as steel bars, wooden slats, concrete, steel pipes, etc. During the operation, the luffing trolley walks on the boom, and can perform circular operations with any radius within the length of the tower crane's boom. Because the shape accuracy of the left and right side panels of the trolley luffing mechanism frame is not high, the trolley luffing mechanism frame welded with the shape of the left and right side panels as the welding reference is likely to cause the shape and position errors of the left and right side panel assembly holes to exceed the design requirements, so that the boring machine cannot compensate for the excessive shape and position errors, which easily produces defective products and causes waste.
[0003] After searching, a Chinese patent with announcement number CN208409013U discloses a welding tool for the frame of a trolley variable-length mechanism. By changing the welding positioning reference from the lower-precision frame side panel shape to the higher-precision frame side panel assembly holes, the shape and position errors between the assembly holes on the sides of the frame after welding are reduced, thus overcoming the defect that the shape and position errors of the assembly holes on the side panels of the frame exceed the design requirements after the existing frame is welded.
[0004] When the above patent is in use, when the height and length of the frame to be welded change, the size of the frame tooling can be adjusted by using the height adjustment pad and the length adjustment pad, but it is not convenient to squeeze and position the width of the frame, and the use effect is poor.

Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0029] Refer to the instruction manual Figure 1-6A tower crane luffing trolley machining tool of this embodiment includes a base 1 and four mounting frames 2, wherein the bottom ends of the two mounting frames 2 are fixedly connected to the top front side of the base 1, and the four mounting frames 2 are provided with a first extrusion assembly 3 and a second extrusion assembly 4. The four first extrusion assemblies 3 include a first connecting frame 301, two limit blocks 302, two first gaskets 303 and two first bolts 304. One side of the plurality of limit blocks 302 and the plurality of first gaskets 303 are respectively fixedly connected to the four first connecting frames 301, and the bottom ends of the plurality of first bolts 304 respectively penetrate the four first connecting frames 301 and are threadedly connected to the four mounting frames 2. The four second extrusion assemblies 4 include a second connecting frame 401, a second gasket 402 and two second bolts 403. One side of the four second gaskets 402 are respectively fixedly connected to the four second connecting frames 401, and the bottom ends of the plurality of second bolts 403 respectively penetrate the four second connecting frames 401 and are threadedly connected to the four mounting frames 2. The tops of the four mounting frames 2 are provided with a third extrusion assembly 5.
[0030] Furthermore, the top ends of the four mounting frames 2 are fixedly connected with a plurality of rods 8, and the top ends of the plurality of rods 8 respectively pass through the four first connecting frames 301 and the four second connecting frames 401. The plurality of rods 8 can limit the deflection of the first connecting frames 301 and the second connecting frames 401.
[0031] Furthermore, the four third extrusion assemblies 5 each include a bracket 501, a threaded rod 502, a pressure plate 503, a third gasket 504 and a threaded sleeve 505. The bottom ends of the four brackets 501 are respectively fixedly connected to the four mounting frames 2, the bottom ends of the four threaded rods 502 are respectively fixedly connected to the four brackets 501, the four pressure plates 503 and the four threaded sleeves 505 are respectively movably mounted on the four threaded rods 502, the top ends of the four third gaskets 504 are respectively fixedly connected to the four pressure plates 503, the bottoms of the four pressure plates 503 are movably provided with springs 506, and the four springs 506 are respectively movably mounted on the four threaded rods 502, the top ends of the four brackets 501 are respectively fixedly connected to the vertical rods 507, and the top ends of the four vertical rods 507 respectively pass through the four pressure plates 503.
[0032] Furthermore, a movable component 6 is provided on the base 1, and the movable component 6 includes a screw rod 601, a slider 602, a fixed plate 603 and a handle 604. The rear end of the screw rod 601 is movably connected to the base 1 through a bearing, the slider 602 is threadedly connected to the screw rod 601, and the top of the slider 602 is fixedly connected to the fixed plate 603, the two sides of the fixed plate 603 are fixedly connected to the other two mounting frames 2, the front side of the handle 604 is fixedly connected to the screw rod 601, and the top of the base 1 is fixedly connected to two clamping blocks 7, and the rear sides of the two clamping blocks 7 respectively pass through the other two mounting frames 2.
[0033] Among them, rotating the handle 604 drives the screw rod 601 to rotate. Since the slider 602 is threadedly connected to the screw rod 601, the base 1 limits the rotation of the slider 602. Therefore, the screw rod 601 can drive the slider 602 to move forward horizontally, thereby driving the fixing plate 603 to move forward horizontally, and then driving the other two mounting frames 2 to move forward horizontally, adjusting the positions of the other two mounting frames 2, which is easy to use. At the same time, the two blocking blocks 7 can limit the deflection of the other two mounting frames 2 and improve the stability of the other two mounting frames 2.

Similarly, the other three first connecting frames 301 are installed, and they can be squeezed and positioned according to the length of the variable-length trolley. Similarly, the first connecting frame 301 is disassembled, and the first gaskets 303 of different thicknesses are replaced. The second connecting frame 401 is placed on the top of the mounting frame 2, and then the second connecting frame 401 is fixed by two second bolts 403, and the four second gaskets are used. 402 is used to limit the position of the luffing trolley, and it can be squeezed and positioned according to the width of the luffing trolley. The pressure plate 503 is placed on the top of the bracket 501, and then the threaded sleeve 505 is sleeved on the threaded plug rod 502, and the pressure plate 503 is limited. The luffing trolley is limited by the third gasket 504, and it can be squeezed and positioned according to the height of the luffing trolley. The structure is simple and the use effect is good. At the same time, the rebound of the spring 506 can drive the pressure plate 503 to move upward to facilitate the removal of the pressure plate 503. The vertical rod 507 limits the pressure plate 503 to prevent the pressure plate 503 from deflecting when it moves vertically.
