Description

Technical Field

[0001] The utility model relates to the technical field of transmission maintenance, and in particular to a double-hook transmission shaft system hoisting tool. Background Art

[0002] During the inspection of the transmission, the main shaft and the counter shaft need to be hoisted out to the designated location to check the wear of the gears, etc. Since the main shaft and the counter shaft cannot be directly hoisted by a hoisting machine, it is necessary to use tools to fix the main and counter shafts first, and then various hoisting machines are used to lift the hoisting tools.

[0003] However, during the lifting process, the main shaft and the shift fork are fixed together. If only the main shaft is lifted, the shift fork needs to be removed in advance, and then installed after the inspection is completed, which adds many unnecessary steps and greatly affects work efficiency. Utility Model Content

[0004] The utility model provides a double-hook transmission shaft system hoisting tool, which can simultaneously fix and hoist the shift fork while hoisting the main shaft and the secondary shaft, thereby improving the maintenance efficiency.

[0005] To this end, the technical solutions adopted are as follows:

[0006] A double-hook transmission shaft system lifting tool is used for lifting the main shaft and secondary shaft of the transmission, comprising a horizontally arranged supporting plate, a lifting plate is fixed on the top of the supporting plate, a main shaft sleeve, a secondary shaft sleeve, a double-hook assembly and a fork connecting assembly capable of clamping and fixing the top of the fork; the double-hook assembly comprises a supporting rod horizontally fixed above the supporting plate, and a main shaft lifting hook and a secondary shaft lifting hook, the main shaft lifting hook and the secondary shaft lifting hook are both N-shaped structures, including a horizontal plate that is perpendicular to the supporting rod and slidably connected to the supporting rod, and two lifting rods that are perpendicular to the horizontal plate and respectively located at both ends thereof, the bottom ends of the two lifting rods are fixed with connecting hooks bent inwardly; the connecting hooks on the main shaft lifting hook and the secondary shaft lifting hook are respectively clamped on the gears of the main shaft and the secondary shaft.

[0007] A further technical solution is that the fork connecting assembly includes a connecting tube, the connecting tube is vertically fixed to the bottom of the support plate, and a locking bolt is passed through the side wall of the connecting tube.

[0008] A further technical solution is that the horizontal plate is provided with fastening bolts, and the fastening bolts can penetrate the side wall of the horizontal plate and abut against the support rod.

[0009] A further technical solution is that the fastening bolts are located on the top of the horizontal plate.

[0010] A further technical solution is that a copper sleeve is sleeved at the connection between the horizontal plate and the support rod, and the copper sleeve is fixed to the horizontal plate.

[0011] A further technical solution is that two vertically arranged mounting seats are fixed on both ends of the upper surface of the support plate, and the support rod is located between the two mounting seats and fixed by the two mounting seats.

[0012] A further technical solution is that the hanging plate can be slidably connected to the support rod.

[0013] The working principle and beneficial effects of this application are:

[0014] 1. Through the main shaft lifting hook and the secondary shaft lifting hook, in conjunction with the main shaft sleeve and the secondary shaft sleeve, the main shaft and the secondary shaft can be lifted and placed in the designated position for maintenance, meeting the lifting requirements for the main shaft and the secondary shaft.

[0015] 2. While hoisting the main shaft and the secondary shaft, the shift fork can be hoisted through the shift fork connecting assembly, avoiding the disassembly and assembly of the shift fork during maintenance and improving the maintenance efficiency.

[0016] 3. The main shaft connection assembly and the secondary shaft connection assembly can act independently without interfering with each other, so that the main shaft and the secondary shaft can be hoisted separately to meet more usage requirements. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5 As shown, a double-hook transmission shaft system hoisting tool is used to hoist the main shaft and counter shaft of the transmission, including a horizontally arranged support plate 100, a hoisting plate 10 is fixed on the top of the support plate 100, a main shaft sleeve 11, a counter shaft sleeve 12, a double hook assembly 13 and a fork connecting assembly 14 capable of clamping and fixing the top of the fork are fixed on the support plate 100; the double hook assembly 13 includes a support rod 131 horizontally fixed above the support plate 100, and a main shaft hoisting hook 132 and a counter shaft The lifting hook 133, the main shaft lifting hook 132 and the secondary shaft lifting hook 133 are both N-shaped structures, including a horizontal plate 134 perpendicular to the support rod 131 and slidably connected thereto, and two lifting rods 135 perpendicular to the horizontal plate 134 and respectively located at both ends thereof, and the bottom ends of the two lifting rods 135 are fixed with connecting hooks 136 bent inwardly; the connecting hooks 136 on the main shaft lifting hook 132 and the secondary shaft lifting hook 133 are respectively clamped on the gears of the main shaft and the secondary shaft.

[0026] When the application is in use, the main shaft lifting hook 132 and the secondary shaft lifting hook 133 are first moved to a position on the support rod 131 that does not interfere with the insertion of the main shaft and the secondary shaft into the main shaft sleeve 11 and the secondary shaft sleeve 12. After the positions of the main shaft and the secondary shaft are positioned, the main shaft lifting hook 132 and the secondary shaft lifting hook 133 are moved back and respectively engaged with the gears of the main shaft and the secondary shaft. In this way, the main shaft and the secondary shaft can be fixed and lifted up. At the same time, the top end of the shift fork is clamped by the shift fork connecting assembly 14, so that the shift fork can be connected to the main shaft and the secondary shaft to lift and transport them to the maintenance location. The main shaft and the secondary shaft can also be lifted separately, and maintenance personnel are required to help maintain balance during transportation.

[0027] Thus, the main shaft and the secondary shaft can be lifted by the main shaft lifting hook 132 and the secondary shaft lifting hook 133 in cooperation with the main shaft sleeve 11 and the secondary shaft sleeve 12, and placed in a designated position for maintenance, thereby meeting the lifting requirements for the main shaft and the secondary shaft. While the main shaft and the secondary shaft are being lifted, the fork can be lifted by the fork connecting assembly 14, thereby avoiding the disassembly and assembly of the fork during maintenance, thereby improving the maintenance efficiency. The main shaft connecting assembly and the secondary shaft connecting assembly can act independently without interfering with each other, so that the main shaft and the secondary shaft can be lifted independently, thereby meeting more usage requirements.

[0028] like Figure 4-Figure 5 As shown, an embodiment of the fork connecting assembly 14 includes a connecting tube 141, which is vertically fixed to the bottom of the support plate 100, and a locking bolt 142 is passed through the side wall of the connecting tube 141. When hoisting, the cylindrical upper end of the fork is inserted into the connecting tube 141, and then locked and fixed by the locking bolt 142.

[0029] like Figure 1-Figure 3 As shown, the horizontal plate 134 is provided with a fastening bolt 1341, which can penetrate the side wall of the horizontal plate 134 and abut against the support rod 131, and the fastening bolt 1341 is located at the top of the horizontal plate 134. Therefore, when the main shaft hoisting hook 132 and the secondary shaft hoisting hook 133 move, the fastening bolt 1341 is loosened, and then locked after the movement is completed, so as to prevent the main shaft hoisting hook 132 and the secondary shaft hoisting hook 133 from sliding under force during the hoisting process, ensure the stability of the system, and strengthen the connection strength between the main shaft hoisting hook 132 and the secondary shaft hoisting hook 133 and the main shaft and secondary shaft gears, and fix the fastening bolt 1341 to the top of the horizontal plate 134, so that the layout is more reasonable and the operation is convenient.

[0030] In addition, since the horizontal plate and the support rod 131 often slide relative to each other during use, a copper sleeve 1342 is sleeved at the connection between the horizontal plate and the support rod 131, and the copper sleeve 1342 is fixed to the horizontal plate 134, thereby being more wear-resistant and preventing rust.

[0031] Two vertically arranged mounting seats 101 are fixed at both ends of the upper surface of the support plate 100, and the support rod 131 is located between the two mounting seats 101 and fixed by the two. And the hoisting plate 10 can be slidably connected to the support rod 131. In this way, the moving distance of the main shaft hoisting hook 132 and the secondary shaft hoisting hook 133 is larger, and more main and secondary shaft models are adapted. In addition, the hoisting plate 10 on the support rod 131 is more conducive to the balance of the system during hoisting, and the layout is more reasonable.

[0032] It is worth noting that the main shaft hoisting hook 132 and the secondary shaft hoisting hook 133 can be changed in size to hoist main shafts and secondary shafts of different specifications, for example, by adjusting the length of the hoisting rod 135.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
