DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figs. 1-2 The utility model provides a micro track crane device, which comprises a track crane 1, a support member 2 and a transverse moving type lifting tool 3. Two track cranes 1 are slidably arranged on external tracks as basic carriers for moving the device. Two support members 2 are respectively mounted on the top of the track cranes 1, and the top of each support member 2 carries a transverse moving type lifting tool 3 for performing material lifting operations.

[0021] Support 2 includes two driving members 21, a telescopic member 22, a transmission member 23 and a servo motor 24. The lower driving member 21 is arranged at the top of the track trolley 1, and the upper driving member 21 is arranged at the bottom of the transverse trolley 3. The telescopic member 22 is arranged between the two driving members 21. The transmission member 23 is arranged on the outer wall of the two driving members 21. The servo motor 24 is arranged on the outer wall of one of the driving members 21.

[0022] The transmission member 23 is used to realize linkage between the two driving members 21. The servo motor 24 is used to provide power for the driving member 21. The driving member 21 is used to drive the telescopic member 22 to contract or expand, so as to adjust the height and the occupied space area of the transverse trolley 3.

[0023] Specifically, referring to Fig. 2 , the driving member 21 is composed of a mounting frame 211, a bidirectional screw 212 and a sliding block 213. The mounting frame 211 serves as a basic carrier. The bidirectional screw 212 can rotate through the inside of the mounting frame 211, and one end of the bidirectional screw 212 is connected with the output end of the servo motor 24. The two sliding blocks 213 are assembled on the outer wall of the bidirectional screw 212 in a threaded sleeve manner. By using the reverse thread characteristics of the two ends of the bidirectional screw 212, when the servo motor 24 drives the bidirectional screw 212 to rotate, the two sliding blocks 213 can move towards or away from each other. The lower driving member 21 is fixed to the top of the track trolley 1, and the upper driving member 21 is fixed to the bottom of the transverse trolley 3, forming a driving basis for linkage in the up-down direction. The servo motor 24 serves as a power source and is installed on the outer wall of one of the driving members 21, providing power for the rotation of the bidirectional screw 212 and precisely controlling the action of the driving member 21.

[0024] Specifically, referring to Fig. 2 , the telescopic member 22 includes a scissor-type telescopic frame 221 and four hinged seats 222 hinged to the four end heads of the scissor-type telescopic frame 221. The hinged seat 222 is connected with the adjacent sliding block 213. When the sliding block 213 is driven to move by the driving member 21, the scissor-type telescopic frame 221 realizes contraction or expansion through the hinged structure, thereby driving the transverse trolley 3 to ascend or descend and completing height adjustment, while changing the overall occupied space area of the device.

[0025] Specifically, referring to Fig. 2The transmission member 23 comprises two support frames 231 arranged on the mounting frames 211 respectively; a sleeve rod 232 rotatably penetrating one of the support frames 231; a cross shaft 233 rotatably penetrating the other support frame 231, the cross shaft 233 being slidably inserted into the sleeve rod 232 at one end close to the sleeve rod 232; gear wheels 234 arranged on the cross shaft 233 and the sleeve rod 232 penetrating end and one end of the two bidirectional screw rods 212, the adjacent two gear wheels 234 being meshed with each other; the synchronous linkage of the two driving members 21 is realized through the transmission of the gear wheels 234 and the cooperation of the cross shaft 233 and the sleeve rod 232, the action consistency of the two side support members 2 is ensured, the horizontal moving type lifting appliance 3 is stably adjusted, and meanwhile, when the distance between the two driving members 21 changes, the transmission distance can be changed through the sliding cooperation between the cross shaft 233 and the sleeve rod 232, so that the transmission of the two driving members 21 is always kept.

[0026] Specifically, referring to Fig. 2 A plurality of sleeves 4 are arranged between the upper and lower mounting frames 211, which provide auxiliary support and guiding function when the telescopic member 22 acts, enhance the overall structural stability of the device, and avoid shaking or deviation during the adjustment process.
