[0001] The invention relates to the technical field of guide shoe conveying, in particular to an elevator guide shoe suspension conveying device. Background Art

[0002] The guide shoe is a sliding nylon block between the elevator guide rail and the car. It can fix the car on the guide rail so that the car can only move up and down. The guide shoe needs to go through painting and heat treatment during the manufacturing process. During this period, the guide shoe needs to be sent to a special process room through a hanging device for processing.

[0003] A Chinese utility model patent with publication number CN207712852U discloses a suspended conveying device, comprising: a plurality of conveying frames driven by a driving shaft, the conveying frames comprising: a driving wheel set, a traveling trolley connected to the driving wheel set, a first parking device arranged at the front end of the traveling trolley, and a second parking device arranged at the rear end of the traveling trolley, and a flexible brake line; the brake line is connected between the second parking device and the driving wheel set; or, the brake line is connected between the first parking device and the driving wheel set; the first parking device or the second parking device is hinged to the traveling trolley through a hinge shaft.

[0004] A Chinese utility model patent with publication number CN207404356U discloses a suspended conveying device, including an overhead track, a traction chain and a sling, wherein a nozzle is arranged inside the overhead track, and the nozzle is arranged at at least two positions inside the overhead track; the upper wall and the side wall of the overhead track are provided with perforations, the inlet end of the nozzle is connected to an oil pipeline, and the oil pipeline passes through the perforations and is connected to an oil mist collector; an opening edge arranged at the lower end of the overhead track is provided with an oil baffle extending into the interior of the overhead track, an oil drain hole close to the lower end of the overhead track is provided on the side wall of the overhead track, the oil drain hole is connected to an oil drain pipe, and the oil outlet end of the oil drain pipe is connected to an oil collecting tank; the oil mist collector is connected to the oil collecting tank.

[0005] The suspended conveying device includes a traveling mechanism that cooperates with the guide rail and a boom suspended under the traveling mechanism, and the conveyed parts are placed on the boom. Traditional suspended conveying devices require manual auxiliary control by the operator in the process of removing the boom from the traveling mechanism.

In order to reduce the manual operation steps, some suspended conveying devices are equipped with an electric locking mechanism on the traveling mechanism to achieve the locking and release of the boom. However, this will undoubtedly increase the overall design and manufacturing cost of the conveying device, and is not suitable for conveying devices with a large number of booms. Based on this, how to design a conveying device that can automatically lock and release the boom without the need for an additional electric locking mechanism is a problem that technical personnel in this field need to solve.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 and Figure 3 As shown, this embodiment provides an elevator guide shoe suspended conveying device, including a guide rail 1 and a traveling mechanism 2 matched with the guide rail 1, the traveling mechanism 2 includes a trolley 201 and a winding drum 202 rotatably matched with the trolley 201, and two winding ropes 203 are wound on the winding drum 202; a driving unit is installed on the trolley 201 to drive the trolley 201 to move along the guide rail 1, and the specific structure of the driving unit is the prior art in this field and is not elaborated in detail here; a motor for driving the winding drum 202 to reciprocate is also installed on the trolley 201, and the winding rope 203 is wound when the winding drum 202 rotates forward, and the winding rope 203 is released when the winding drum 202 rotates reversely.

[0029] like Figure 1 and Figure 3As shown, a lifting platform 204 is fixedly installed at the bottom of the winding rope 203. When the winding drum 202 winds up the winding rope 203, the lifting platform 204 rises; when the winding drum 202 releases the winding rope 203, the lifting platform 204 descends; a locking unit is installed on the lifting platform 204, and the locking unit includes two horizontal shafts 205 that are rotatably matched with the lifting platform 204. The two horizontal shafts 205 are parallel to each other, and each horizontal shaft 205 is fixedly installed with two rotating arms 206, and the corresponding two rotating arms 206 are fixedly installed on each horizontal shaft 205. 6, a limit arm 207 is installed between the two ends of the lifting platform 204, the limit arm 207 is a cylindrical structure and is parallel to the horizontal axis 205; the two limit arms 207 have a first state of mutual contact and a second state of mutual separation; a stopper 208 is fixedly installed at the position corresponding to each rotating arm 206 on the lifting platform 204, when the rotating arm 206 is in a horizontal state, the two limit arms 207 are in the first state, and the bottom of the rotating arm 206 is in contact with the stopper 208; a torsion spring 209 is connected between the horizontal axis 205 and the lifting platform 204. The elevator guide shoe suspension conveying device also includes a lifting ring 3 that cooperates with the walking mechanism 2, and the lifting ring 3 includes a shaped frame 301 with an opening facing upward and a top rod 302 connected to the top of the shaped frame 301, the top rod 302 is in a horizontal state, and a suspension rod 4 is installed at the bottom of the shaped frame 301, and the guide shoe is suspended on the suspension rod 4.

[0030] Specifically, after the operator hangs the guide shoes to be transported on the boom 4 in sequence, the trolley 201 moves along the guide rail 1 to a predetermined position, that is, a position above the boom 4; at this time, the two limit arms 207 are in Figure 1In the first state shown, the top rod 302 is located below the two limit arms 207; then the motor drives the winding drum 202 to rotate in the opposite direction to release the winding rope 203, and the lifting platform 204, the horizontal axis 205, the rotating arm 206, the limit arm 207, the stopper 208 and the torsion spring 209 descend synchronously. During the descent of the limit arm 207, it is attached to the top rod 302 and an interaction force is generated between the top rod 302 and the top rod 302. The top rod 302 pushes the two limit arms 207 to rise, the horizontal axis 205, the rotating arm 206 and the limit arm 207 rotate, and the torsion spring 209 is deformed. ; As the lifting platform 204 continues to descend, the top rod 302 separates from the limit arm 207, and the horizontal shaft 205, the rotating arm 206 and the limit arm 207 rotate in the opposite direction to reset, until the rotating arm 206 fits with the stop block 208, and the two limit arms 207 return to the first state; then, the motor drives the winding drum 202 to rotate forward to reel in the winding rope 203, and the lifting platform 204, the horizontal shaft 205, the rotating arm 206, the limit arm 207, the stop block 208 and the torsion spring 209 rise synchronously, and then the limit arm 207 fits with the top rod 302, and drives the lifting ring 3 and the suspension rod 4 as a whole to move upward. The lifting platform 204, the horizontal axis 205, the rotating arm 206, the limiting arm 207, the stopper 208, the torsion spring 209, the ring 3 and the suspension rod 4 are synchronously lowered, the bottom of the suspension rod 4 contacts the workbench first, the ring 3 and the suspension rod 4 no longer continue to descend, the horizontal axis 205, the rotating arm 206 and the limiting arm 207 are lowered, and the lifting platform 204, the horizontal axis 205, the rotating arm 206 and the limiting arm 207 are lowered. 07 rotates under the action of external force, and the two limit arms 207 change from the first state to the second state, and a gap appears between the two limit arms 207. Then the motor drives the winding drum 202 to rotate forward to reel in the winding rope 203, and the lifting platform 204, the horizontal axis 205, the rotating arm 206, the limit arm 207, the stopper 208 and the torsion spring 209 rise until the limit arm 207 rises from the bottom of the top rod 302 to the top of the top rod 302. Finally, the horizontal axis 205, the rotating arm 206 and the limit arm 207 rotate in the opposite direction to reset, and the limit arm 207 changes from the second state back to the first state. The above completes the transportation of the lifting ring 3 and the lifting rod 4.

[0031] like Figure 1 and Figure 2As shown, a gear 210 is fixedly sleeved on the horizontal shaft 205, and a control console 211 located above the top rod 302 is slidably installed on the lifting platform 204 in the vertical direction. The control console 211 will rise relative to the lifting platform 204 under the action of an external force, and after the external force disappears, the control console 211 will fall and reset relative to the lifting platform 204 under the action of gravity; a vertical rack 212 is fixedly installed on the control console 211 corresponding to the position of each gear 210; a positioning groove 213 is opened on the side wall of the control console 211, and a horizontal elastic telescopic rod 214 is fixedly installed on the lifting platform 204, one end of the elastic telescopic rod 214 is adapted to the positioning groove 213, and a wedge block 215 is fixedly installed on the other end of the elastic telescopic rod 214; a rigid rod 216 corresponding to the position of the wedge block 215 is fixedly installed on the trolley 201; a roller 217 is rotatably installed on the bottom end of the rigid rod 216 to reduce the friction between the wedge block 215 and the wedge block 215 when moving relative to the wedge block 215.

[0032] Specifically, in the initial state, the two limit arms 207 are in the first state, the rack 212 and the gear 210 are in a separated state, one end of the elastic telescopic rod 214 is in contact with the side wall of the console 211, and there is an interaction force between the two; when the lifting ring 3 and the suspension rod 4 are lifted, the push rod 302 enters the upper part of the limit arm 207 from the bottom of the limit arm 207 and pushes the limit arm 207 from the first state to the second state. During this process, the gear 210 rotates, but remains separated from the rack 212; when the lifting ring 3 and the suspension rod 4 are released, when the bottom of the suspension rod 4 contacts the workbench, the lifting ring 3 and the suspension rod 4 no longer continue to descend, while the lifting platform 204 and the console 211 continue to descend, and the bottom of the console 211 is in contact with the push rod 302 and rises relative to the lifting platform 204 under the action of the push rod 302. During this process, the rack 212 is relative to the gear 210 and meshes with the gear 210 When the lifting platform 204 is in the closed state, the gear 210 rotates and drives the horizontal shaft 205, the rotating arm 206 and the limiting arm 207 to rotate synchronously. The two limiting arms 207 change from the first state to the second state. During the rising of the control console 211 relative to the lifting platform 204, the positioning groove 213 also rises relative to the elastic telescopic rod 214 until one end of the elastic telescopic rod 214 is inserted into the positioning groove 213 under the action of elastic force. The control console 211 can no longer rise relative to the lifting platform 204. At this time, the motor stops working and the lifting platform 204 no longer continues to descend. In this state, since the two limiting arms 207 are in the second state, as long as the motor drives the winding drum 202 to rotate forward to reel in the winding rope 203, during the rising process of the lifting platform 204, the top rod 302 can be moved out from the gap between the two limiting arms 207 to the bottom of the limiting arms 207, so as to complete the release of the lifting ring 3 and the suspension rod 4. The motor continuously drives the reel 202 to rotate forward to reel the reel rope 203, and the roller 217 contacts the inclined surface of the wedge block 215 and pushes the wedge block 215 to translate. During the translation of the wedge block 215, the telescopic part of the elastic telescopic rod 214 is translated, so that the elastic telescopic rod 214 moves out of the positioning groove 213, and the control console 211 is reset relative to the lifting platform 204 under the action of gravity. At this point, the conveying action of the lifting ring 3 and the suspension rod 4 is completely completed. In summary, when conveying the lifting ring 3 and the suspension rod 4 in this embodiment, as long as the lifting platform 204 is controlled to descend and then rise, the lifting of the lifting ring 3 and the suspension rod 4 can be realized; similarly, as long as the lifting platform 204 is controlled to descend and then rise, the release of the lifting ring 3 and the suspension rod 4 can be realized. In summary, this embodiment does not require an additional electric locking mechanism. It only relies on the motor to drive the lifting platform 204 to lift and lower, so as to automatically lift and release the lifting ring 3 and the lifting rod 4. It is simple to operate and has a simple structure, which significantly reduces the design and manufacturing costs of the device.

[0033] like Figure 5As shown, the upper surface of the push rod 302 is semicircular in shape to ensure that the push rod 302 can push the limit arm 207 when it rises from the bottom of the limit arm 207 relative to the limit arm 207, and the lower surface of the push rod 302 is adapted to the two limit arms 207 in a fitted state. In this way, after the lower surface of the push rod 302 is fitted with the limit arm 207 in the first state, the probability of movement relative to the limit arm 207 is greatly reduced, thereby ensuring the stability of the lifting ring 3 and the lifting rod 4 during transportation.

[0034] like Figure 4 and Figure 5 As shown, a receiving groove 303 is provided on the lower surface of the push rod 302, a piston block 304 is slidably installed in the receiving groove 303 along the vertical direction, and a telescopic spring 305 is connected between the piston block 304 and the inner wall of the receiving groove 303. A pull wire 306 that is always kept in a tensioned state is fixedly connected to the upper surface of the piston block 304, and a wire groove that cooperates with the pull wire 306 is provided inside the push rod 302; the suspension rod 4 includes a first section 401 fixedly connected to the mold frame 301, and a second section 402 that slides along the vertical direction with the first section 401, and a positioning ring 403 that cooperates with the second section 402 is fixedly installed on the first section 401; the bottom end of the pull wire 306 passes through the mold frame 301 and the first section 401, and is fixedly connected to the second section 402.

[0035] Specifically, in the initial state, the bottom surface of the positioning ring 403 is in contact with the second section 402. When the limiting arm 207 drives the top rod 302 to rise, the bracket 301, the first section 401 and the positioning ring 403 will rise synchronously first, and the second section 402 will remain stationary. During this process, the pull wire 306 will apply tension to the piston block 304, so that the piston block 304 compresses the telescopic spring 305 and rises relative to the receiving groove 303, thereby reducing the air pressure in the area between the piston block 304 and the limiting arm 207 in the receiving groove 303, and then the piston block 304 sucks the limiting arm 207, further promoting the stability between the limiting arm 207 and the top rod 302; when the top surface of the positioning ring 403 is in contact with the second section 402, the lifting ring 3 and the lifting rod 4 rise as a whole, and the piston block 304 remains stationary relative to the receiving groove 303.

[0036] like Figure 4 and Figure 6As shown, a plurality of suspension rods 404 for suspending guide shoes are rotatably installed on the second section 402, and there are two groups of suspension rods 404, each group is evenly arranged in the vertical direction. When the suspension rod 4 is placed on the workbench, the suspension rods 404 are in a horizontal state, which is convenient for the operator to take the guide shoe. When the suspension rod 4 is in a suspended state, the suspension rod 404 is in an inclined state to prevent the guide shoe from sliding off the suspension rod 404, and a protrusion 405 is provided on the suspension rod 404; a vertical rod 406 is fixedly installed at the position of the suspension rod 404 at the bottom of the first section 401, and a push block 407 fitting with the protrusion 405 is fixedly installed at the position corresponding to the suspension rod 404, and a push block 407 fitting with the protrusion 405 is fixedly installed on the vertical rod 406 at the position corresponding to each protrusion 405.

[0037] In the initial state, the suspension rod 404 is in a horizontal state. When the bracket 301 and the first section 401 rise first, the vertical rod 406 and the push block 407 will rise. The push block 407 will move relative to the protrusion 405 and push the suspension rod 404 to rotate upward until the top surface of the positioning ring 403 is in contact with the second section 402. Thereafter, the lifting ring 3 and the suspension rod 4 rise as a whole, and the suspension rod 404 also always maintains this angle. In this way, when the lifting ring 3 and the suspension rod 4 are in a suspended state, the guide shoe is not easy to fall off the suspension rod 404.

[0038] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
