[0043] The transportation engineering of vehicle parts is related to the smooth operation of the vehicle production line and product quality. Some vehicle parts need to use a special lifting appliance for lifting, for example, when a frequency converter needs to be assembled, the frequency converter needs to be lifted to a handling trolley first by cooperating with the lifting appliance. After the handling is completed, it must be confirmed again by scanning the code through the scanning gun. This link is the key step to prevent the lifting appliance from lifting incorrectly and ensure that the parts are accurately delivered to the designated position.

[0044] However, according to the applicant's observation and research, it is found that during the lifting operation of the frequency converter, after the frequency converter is placed on the handling trolley, the operator needs to hold the scanning gun and scan the bar code or two-dimensional code on each frequency converter one by one. This process not only takes a long time, but also increases the complexity of human operation. Especially when facing a large number of part lifting tasks, the code scanning method is particularly cumbersome, resulting in low work efficiency of the entire lifting operation. This situation not only prolongs the production cycle, but also increases the labor cost, which becomes one of the key factors restricting the improvement of production efficiency.

[0045] In view of this, the utility model provides a bridge type lifting appliance to solve the above technical problems.

[0046] Please refer to Figures 1 to 3 In an embodiment of the utility model, the bridge type lifting appliance 1000 is used for lifting vehicle parts, which comprises a lifting frame 1, a lifting assembly 2, a mounting seat 3, a clamping assembly 4 and a scanner 5, wherein the lifting frame 1 comprises a lifting platform 11 and a connecting frame 12 mounted on the top of the lifting platform 11, and a clearance through hole 111 is formed in the middle of the lifting platform 11; the lifting assembly 2 is mounted on the lifting platform 11, and the lifting assembly 2 is used for grabbing vehicle parts, and the information code of the vehicle parts faces the clearance through hole 111; the mounting seat 3 is mounted on the top of the lifting platform 11; the clamping assembly 4 is mounted on the mounting seat 3; the scanner 5 comprises a main body and a scanning head arranged at one end of the main body; the clamping assembly 4 comprises a clamping jaw 41, the main body is mounted on the clamping jaw 41, and the scanning head faces the clearance through hole 111, so that the scanning head can scan the information code.

[0047] The technical scheme provided by the embodiment is that the mounting seat 3 and the clamping assembly 4 are arranged on the top surface of the lifting platform 11, and the scanner 5 is clamped in the clamping jaw 41, so that after the lifting assembly 2 successfully grabs the vehicle parts, the scanner 5 can immediately scan the information code on the vehicle parts, and the operator does not need to manually hold the scanner 5 to scan and confirm the vehicle parts, which can effectively eliminate the waste of working hours caused by scanning and confirmation, thereby improving the working efficiency of the lifting operation. Meanwhile, in the embodiment, the mounting seat 3 and the clamping assembly 4 are detachably connected, so that different clamping assemblies 4 can be replaced according to different models of the scanner 5.

[0048] Further, please refer to Figure 3 With Figure 4 In an embodiment of the utility model, the clamping assembly 4 further comprises a bracket 42, a ball seat 43 and a ball head rod 44, the bracket 42 is mounted on the top of the mounting seat 3, the ball seat 43 is mounted on one side of the bracket 42 close to the clearance through hole 111, one end of the ball head rod 44 is a spherical joint, the spherical joint is rotatably accommodated in the ball seat 43, and the other end of the ball head rod 44 is connected with the clamping jaw 41. The bracket 42 is used for providing support for the ball seat 43, the ball seat 43 and the clamping jaw 41 are connected through the ball head rod 44, so that the clamping jaw 41 can be omnidirectionally rotated, thereby facilitating the adjustment of the angle of the clamping jaw 41 to drive the scanner 5 to adjust the angle, and the scanning head can be conveniently aligned with the information code at different positions. For a batch of vehicle parts of the same model, the positions of the information codes are basically the same, so when lifting the same batch of vehicle parts, the angle of the scanner 5 only needs to be adjusted when lifting the first vehicle part of the same model, and the lifting operation of the subsequent vehicle parts of the same model does not need to be adjusted again. This arrangement improves the applicability of the clamping assembly 4, so that it is applicable to scanning vehicle parts of multiple models.

[0049] In addition, please refer toFigure 4 In the embodiment of the utility model, the clamping assembly 4 further comprises a knob lock rod 45, the knob lock rod 45 comprises a locking screw rod 451 and a rotating knob 452 fixedly installed at one end of the locking screw rod 451, the other end of the locking screw rod 451 is in threaded connection with the support 42, and the end of the locking screw rod 451 away from the rotating knob 452 extends into the inside of the ball seat 43 and abuts against the ball joint to compress or loosen the ball joint. By manually rotating the rotating knob 452, the locking screw rod 451 can be driven to rotate, when rotating clockwise, the locking screw rod 451 cooperates with the ball seat 43 to compress the ball head rod 44, at this time, the ball head rod 44 will not rotate, thereby fixing the clamping jaw 41 at a specific inclination angle. When it is needed to adjust the inclination angle of the clamping jaw 41, only need to rotate the rotating knob 452 counterclockwise to loosen the locking screw rod 451 to the ball head rod 44, the inclination angle of the clamping jaw 41 can be conveniently adjusted.

The cooperation of the sliding groove and the sliding rail arranged between the locking clamp 412 and the bearing frame 411 makes the locking clamp 412 not separate from the bearing frame 411 due to gravity, when the two locking clamps 412 move away from each other, the range of the clamping space becomes larger, at this time, the scanner 5 can be removed, when the two locking clamps 412 approach each other, the range of the clamping space is reduced, at this time, the scanner 5 can be locked in the clamping space.

[0051] The implementation form of the locking mechanism between the locking clamp 412 and the bearing frame 411 also includes various forms, and in an embodiment of the utility model, the clamping jaw 41 further includes a transmission locking rod 413, the transmission locking rod 413 includes a transmission screw rod 4131 and a compression knob 4132, the compression knob 4132 is fixedly installed at one end of the transmission locking rod 413, the locking clamp 412 is provided with a fixed through hole, the side of the bearing frame 411 facing the locking clamp 412 is provided with a threaded hole, the transmission screw rod 4131 is arranged in the fixed through hole, and the end of the transmission screw rod 4131 away from the compression knob 4132 is screwed into the threaded hole, and the compression knob 4132 is arranged in close contact with the side of the locking clamp 412 away from the bearing frame 411. Through this setting, the locking clamp 412 can be loosened or compressed by rotating the compression knob 4132, and specifically, after the scanner 5 is placed in the clamping space, the compression knob 4132 is rotated clockwise, the transmission locking rod 413 gradually extends into the threaded hole, and under the action of the compression knob 4132, the locking clamp 412 gradually approaches each other, because the scanner 5 is difficult to compress, finally the cooperation between the threaded hole and the transmission locking rod 413 and the cooperation between the compression knob 4132 and the side wall of the locking clamp 412 will form a set of pulling force, so that the locking clamp 412 can clamp the scanner 5. In another embodiment, the locking clamp 412 and the bearing frame 411 can provide a pulling force through a tension spring, so that the scanner 5 is clamped.
