Description

Technical Field

[0001] The utility model relates to the technical field of cage car lifting equipment, in particular to a gantry type synchronous lifting mechanism. Background Art

[0002] In the reciprocating vertical lifting system, the pallet and the two-way conveying mechanism are usually used to realize the movement of the cage car entering and exiting the elevator. Taking the cage car entering the elevator as an example, the cage car is first pushed onto the pallet, and then the pallet is lifted to the loading height of the elevator by the two-way conveying mechanism, and then the pallet is driven by the two-way conveying mechanism to dock horizontally into the elevator. However, due to the large width of the pallet, when the two-way conveying mechanism lifts the pallet, the height difference between the two sides of the pallet is easy to occur due to the asynchronous lifting, which leads to the problem of one-side jamming or equipment wear caused by collision during the horizontal docking process of the pallet to the elevator. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a gantry type synchronous lifting mechanism, which can effectively avoid the problem of asynchronous lifting of the pallet.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a gantry type synchronous lifting mechanism, comprising

[0005] The door-type frame comprises a pair of vertical frames arranged opposite to each other, and a top plate is commonly connected to the top of the pair of vertical frames;

[0006] A transverse movement assembly is provided corresponding to the vertical frame and is used to drive the tray to move in a horizontal direction;

[0007] A synchronous lifting component, comprising a motor, a synchronous transmission member, and a lifting member; two lifting members are provided, and are arranged one-to-one with the transverse moving components; one end of the lifting member is connected to the corresponding transverse moving component, and the other end is connected to the motor located on the top plate through a synchronous transmission member; when the motor is started, the two lifting members can drive the two transverse moving components to rise and fall synchronously under the action of the synchronous transmission member;

[0008] The synchronous transmission member includes two synchronous rotating shafts arranged in parallel, the two synchronous rotating shafts are connected to the output shaft of the motor through a transmission part, and one end of the two synchronous rotating shafts located on the same side is commonly connected to a lifting member, and the other end of the two synchronous rotating shafts located on the same side is commonly connected to another lifting member.

[0009] The beneficial effects of the gantry type synchronous lifting mechanism of the utility model are:

[0010] In the synchronous lifting assembly, the synchronous transmission parts are set up to realize the driving of two lifting parts by one motor, so that the two lifting parts drive the two transverse moving parts to rise and fall synchronously; when the pallet is placed on the transverse moving assembly, the left and right sides of the pallet can be respectively located on the two transverse moving assemblies. Since the two transverse moving assemblies are lifted and lowered synchronously, the lifting and lowering movement amount on both sides of the pallet can be kept consistent, thereby avoiding the problem of jamming or collision caused by the tilt of the pallet when it is docked on the elevator in the prior art.

[0011] Further, the lifting member includes a lifting plate, a counterweight, a first chain, a first sprocket, a second chain, and a second sprocket; the first sprocket and the second sprocket are respectively arranged on the two synchronous rotating shafts; the first chain is wound around the first sprocket, and its two ends are respectively connected to the lifting plate and the counterweight; the second chain is wound around the second sprocket, and its two ends are respectively connected to the lifting plate and the counterweight.

[0012] Firstly, by setting the counterweight block, the weight of the lifting plate can be balanced, thereby effectively reducing the power of the motor and achieving the purpose of saving energy; and by setting the double chain (first chain, second chain) and double sprocket (first sprocket, second sprocket), the stability of the lifting plate can be ensured.

[0013] Furthermore, the counterweight block is located above the lifting plate, and is provided with a first through hole and a second through hole for the first chain and the second chain to pass through, respectively. One end of the first chain passes through the first sprocket and is connected to the counterweight block, and the other end passes through the first through hole and is connected to the lifting plate; one end of the second chain passes through the second sprocket and is connected to the counterweight block, and the other end passes through the second through hole and is connected to the lifting plate. This arrangement can make the structure of the lifting member more compact, thereby reducing the installation space of the lifting member on the stand.

[0014] Furthermore, the counterweight block and the lifting plate are both slidably arranged on the stand through a guide mechanism to guide the moving direction of the counterweight block and the lifting plate.

[0015] Furthermore, the stand is symmetrically provided with two slide rails in the vertical direction, the guide mechanism includes two guide parts corresponding to the slide rails, each guide part includes a guide base, at least two guide wheels are provided on the guide base, and the two guide wheels can abut against the slide rails in directions perpendicular to each other. The two guide wheels abutting against the slide rails in the vertical direction can further limit the moving direction of the guide wheels on the slide rails.

[0016] Furthermore, the guide base is connected to the counterweight or lifting plate through a fine-tuning mechanism, the fine-tuning mechanism includes a waist-shaped long groove and a threaded rod, the waist-shaped long groove is arranged on the guide base, and the threaded rod is inserted into the waist-shaped long groove and can be threadedly connected to the counterweight or lifting plate. The position of the guide base is adjusted by the fine-tuning mechanism to adjust the abutment position of the guide wheel on the slide rail.

[0017] Specifically, the transmission part includes two sprocket groups, each of which includes a driving sprocket, a driven sprocket, and a closed-loop chain arranged on the driving sprocket and the driven sprocket in a closed loop; the driving sprockets of the two sprocket groups are coaxially mounted on the output shaft of the motor, and the driven sprockets of the two sprocket groups are coaxially mounted on the two synchronous rotating shafts. The arrangement of the two sprocket groups ensures the synchronization of the rotation of the two synchronous rotating shafts.

[0018] Furthermore, the stand is provided with a position detection member for detecting the lifting height of the transverse moving assembly, so as to facilitate the detection of the highest and lowest positions of the transverse moving assembly.

[0019] Furthermore, both ends of the synchronous rotating shaft are respectively mounted on the top plate through bearing seats.

[0020] Furthermore, a maintenance ladder is installed on one of the stands to facilitate maintenance of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0035] Example

[0036] See attached Figure 1-3 As shown, a gantry type synchronous lifting mechanism of the utility model includes a gantry frame 1, a transverse movement component 2, and a synchronous lifting component, wherein the gantry frame 1 includes a pair of vertical frames 11 arranged opposite to each other, and a top plate 12 is commonly connected to the top of the pair of vertical frames 11. The transverse movement component 2 is arranged in a one-to-one correspondence with the vertical frames 11, and is used to drive the pallet to move in the horizontal direction. The synchronous lifting component includes a motor 3, a synchronous transmission member 4, and a lifting member 5, and two lifting members 5 are provided, and are arranged in a one-to-one correspondence with the transverse movement component 2. One end of the lifting member 5 is connected to the corresponding transverse movement component 2, and the other end is connected to the motor 3 located on the top plate 12 through the synchronous transmission member 4. When the motor 3 is started, the two lifting members 5 can drive the two transverse movement components 2 to rise and fall synchronously under the action of the synchronous transmission member 4.

[0037] Further, see Appendix Figure 2 As shown, the synchronous transmission member 4 includes two synchronous rotating shafts 41 arranged in parallel, and the two ends of the synchronous rotating shafts 41 are respectively mounted on the top plate 12 through bearing seats 42. The two synchronous rotating shafts 41 are connected to the output shaft of the motor 3 through the transmission part, and one end of the two synchronous rotating shafts 41 on the same side is commonly connected to a lifting member 5, and the other end of the two synchronous rotating shafts 41 on the same side is commonly connected to another lifting member 5.

[0038] During operation, the pallet is placed on the two transverse movement components 2. At this time, the left and right sides of the pallet can be respectively located on the two transverse movement components 2, and then the motor 3 is started, and the transmission part immediately drives the two synchronous rotating shafts 41 to rotate synchronously, so that the two lifting members 5 are started synchronously, and the two transverse movement components 2 respectively connected to the two lifting members 5 are immediately raised and lowered synchronously to ensure that the lifting and lowering movement of the left and right sides of the pallet remain consistent; when the pallet rises to the loading height of the elevator, the pallet is still in a horizontal state. At this time, the two transverse movement components 2 can drive the pallet to move horizontally into the elevator.

[0039] In some embodiments, the transmission part includes two sprocket groups 43, each sprocket group 43 includes a driving sprocket, a driven sprocket, and a closed-loop chain 431 arranged on the driving sprocket and the driven sprocket in a closed loop; the driving sprockets of the two sprocket groups 43 are coaxially mounted on the output shaft of the motor 3, and the driven sprockets of the two sprocket groups 43 are coaxially mounted on the two synchronous rotating shafts 41. The arrangement of the two sprocket groups 43 ensures the synchronization of the rotation of the two synchronous rotating shafts 41.

[0040] In some embodiments, see Appendix Figure 3-5 As shown, the lifting member 5 includes a lifting plate 51, a counterweight 52, a first chain 53, a first sprocket 54, a second chain 55, and a second sprocket 56. The lifting plate 51 is located in the stand 11 and is connected to the corresponding transverse assembly 2. The first sprocket 54 and the second sprocket 56 are respectively fixedly mounted on the two synchronous shafts 41; the first chain 53 is wound around the first sprocket 54, and its two ends are respectively connected to the lifting plate 51 and the counterweight 52. The second chain 55 is wound around the second sprocket 56, and its two ends are respectively connected to the lifting plate 51 and the counterweight 52.

[0041] When the two synchronous shafts 41 rotate synchronously, the first sprocket 54 and the second sprocket 56 rotate synchronously. At this time, the end of the first chain 53 and the second chain 55 connected to the lifting plate 51 moves upward (or downward) to achieve the rise (or fall) of the transverse movement component 2, and the end of the first chain 53 and the second chain 55 connected to the counterweight block 52 moves downward (or upward). In the lifting member 5, the weight balance of the lifting and lowering movement of the lifting plate 51 can be achieved through the setting of the counterweight block 52, thereby effectively reducing the output power of the motor 3 and achieving the purpose of saving energy. In the same lifting member 5, the stability of the lifting and lowering of the lifting plate 51 can be further guaranteed through the setting of the double chain (the first chain 53 and the second chain 55) and the double sprocket (the first sprocket 54 and the second sprocket 56).

[0042] Furthermore, since the counterweight 52 and the lifting plate 51 are both arranged on the stand 11, in order to make the overall structure of the lifting member 5 more compact, in some embodiments, the counterweight 52 is arranged above the lifting plate 51, and a first through hole and a second through hole are respectively provided on the counterweight 52 for the first chain 53 and the second chain 55 to pass through. One end of the first chain 53 passes through the first sprocket 54 and is connected to the counterweight 52, and the other end passes through the first through hole and is connected to the lifting plate 51. One end of the second chain 55 passes through the second sprocket 56 and is connected to the counterweight 52, and the other end passes through the second through hole and is connected to the lifting plate 51. This arrangement makes the structure of the lifting member 5 more compact, so as to reduce the installation space of the lifting member 5 on the stand 11.

[0043] Furthermore, in order to guide the moving direction of the lifting member 5, in some embodiments, see the attached Figure 3 , 5 As shown, the counterweight block 52 and the lifting plate 51 are both slidably arranged on the stand 11 through a guide mechanism. Specifically, the stand 11 is symmetrically provided with two slide rails 111 located on both sides of the lifting plate 51 in the vertical direction, and the guide mechanism includes two guide parts arranged one-to-one with the slide rails 111, and each guide part includes a guide base 61, which is fixed to the lifting plate 51 or the counterweight block 52, and at least two guide wheels 62 are arranged thereon, and the two guide wheels 62 can abut against the slide rails 111 in directions perpendicular to each other.

[0044] Exemplarily, when the first chain 53 pulls the lifting plate 51 to move upward, the guide wheel 62 on the lifting plate 51 immediately moves upward along the slide rail 111 to guide the moving direction of the lifting plate 51 .

[0045] During installation, in order to facilitate the adjustment of the contact position of the guide wheel 62 with the slide rail 111. In some embodiments, the guide base 61 is connected to the counterweight 52 or the lifting plate 51 through a fine-tuning mechanism, and the fine-tuning mechanism includes a waist-shaped long groove 611 and a threaded rod 612. The waist-shaped long groove 611 is arranged on the guide base 61, and the threaded rod 612 is penetrated in the waist-shaped long groove 611 and can be threadedly connected with the counterweight 52 or the lifting plate 51. The position of the guide base 61 is adjusted by the fine-tuning mechanism to ensure that the guide wheel 62 can contact the slide rail 111.

[0046] In some embodiments, in order to timely know whether the transverse moving assembly 2 has moved to the highest position or the lowest position, a position detection member for detecting the lifting height of the transverse moving assembly 2 is provided on the stand 11. For example, the position detection member can be a photoelectric sensor.

[0047] It should be noted that the transverse movement assembly 2 is a prior art, and therefore, this embodiment does not elaborate on its structure and principle.

[0048] In some embodiments, in order to facilitate later maintenance, see the attached Figure 1 As shown, a maintenance ladder 7 is installed on one of the stands 11.

[0049] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
