Description

Technical Field

[0001] This invention relates to the field of transfer equipment, specifically to a transfer trolley with an adjustable tilt angle and its usage method. Background Technology

[0002] In automated production lines, the transfer of precision components is a core link connecting various processing steps and ensuring continuous production. It directly determines the overall capacity and processing accuracy of the production line. As industrial manufacturing upgrades towards customization and precision, the receiving modules of different processes within the production line often exhibit different tilt angles and height specifications due to installation layout and processing requirements. Currently, transfer trolleys, as the core equipment for production line transfer, are widely used in scenarios such as material transfer and component docking. However, traditional designs mostly focus on basic movement functions, making it difficult to meet the requirements of flexible angle adjustment, high-precision docking, and anti-displacement of precision components under complex working conditions. Angle mismatch can lead to obstruction of goods transfer, and alignment deviation may cause component collision damage. Therefore, transfer equipment with adjustable angle and precise docking characteristics has become a key support for improving the level of production line automation. To this end, a tilt angle adjustable transfer trolley and its usage method are proposed. Summary of the Invention

[0003] In order to solve the technical problems existing in the prior art, the present invention provides a tilt angle adjustable transfer trolley and a method of using it.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an adjustable tilt angle transfer trolley, including a transfer trolley module, a scissor lift assembly, a deflectable support assembly, and a locking pallet. The transfer trolley module is used to carry the scissor lift assembly, which is installed on top of the transfer trolley module. The deflectable support assembly is installed on top of the scissor lift assembly and is pushed by the scissor lift assembly. The locking pallet is installed on top of the deflectable support assembly and is used to carry goods.

[0005] Preferably, the transfer trolley module includes a transfer trolley body, a push handle, a control box, and docking auxiliary components. The transfer trolley body is used to carry the push handle, the control box, and the docking auxiliary components. The push handle is installed on the side of the transfer trolley body, the docking auxiliary components are installed on one side of the top of the transfer trolley body, and the scissor lifting component is installed on the other side of the top of the push handle. The two sets of docking auxiliary components are respectively installed at both ends of one side of the bottom of the push handle, and both sets of docking auxiliary components face the direction of travel of the transfer trolley body.

[0006] Preferably, the deflectable support assembly includes a deflection base plate, a lateral movement assembly, an inclined support assembly, pneumatic push rods, and a deflection frame. The deflection base plate is fixed to the top of the scissor lift assembly. The lateral movement assembly is installed at the center of the deflection base plate. Two sets of inclined support assemblies are respectively installed on the longitudinal sides of the deflection base plate. Several sets of pneumatic push rods are respectively installed at the top four corners of the deflection base plate. The deflection frame is installed between the top of the lateral movement assembly and the top of the inclined support assembly. The locking tray is fixed to the top of the deflection frame.

[0007] Preferably, the output end of the pneumatic push rod abuts against the bottom of the deflection frame, the pneumatic push rod is electrically connected to the control box, and the pneumatic push rod is used to assist in supporting the deflection frame and finely adjust its support height.

[0008] Preferably, the lateral movement assembly includes a lead screw sliding seat, a transmission rod, a transmission box, a hand crank, and a sliding sleeve seat. The lead screw sliding seat is fixed at the center of the deflection base plate. The transmission rod is horizontally installed in the middle of the deflection base plate, and the output end of the transmission rod is connected to the input end of the lead screw sliding seat. The transmission box is installed at the end of the transmission rod. The hand crank is vertically installed on the lateral side of the deflection base plate, and the end of the hand crank is connected to the transmission box. The sliding sleeve seat is installed at the center of the deflection frame through a connecting plate, and the bottom center of the sliding sleeve seat is engaged with the top of the lead screw sliding seat.

[0009] Preferably, the tilting support assembly includes a support base, support wheels, a support plate, a lateral limiting wheel, and a vertical limiting wheel. The support base is fixed to the longitudinal side of the deflection base plate. Two sets of support wheels are respectively installed on the left and right sides of the support base via rotating shafts. The support plate is placed between the two sets of support wheels, and the top of the support plate is connected to both sides of the deflection frame via a connecting plate. A slot is provided at the center of the support plate, and the bottom of the slot is arc-shaped. The lateral limiting wheel is installed at the middle of the front side of the support base via a rotating shaft, and the lateral limiting wheel is nested in the slot. The vertical limiting wheel is installed at the middle of the rear side of the support base via a rotating shaft.

[0010] Preferably, the deflectable support assembly further includes docking guide plates and contact sensors. A set of docking guide plates is fixed on both sides of the deflection frame, and the two sets of docking guide plates are symmetrically arranged. The contact sensors are disposed inside the docking guide plates.

[0011] Preferably, the locking tray includes a tray body, a locking push rod, and a limiting seat. The tray body is fixed to the top of the deflection frame, the locking push rod is installed at the center of one side of the tray body, and the two sets of limiting seats are respectively installed at both ends of one side of the tray body.

[0012] Preferably, a pin block is installed at the top of the locking push rod, and the pin block is used to lock the carrier after being nested with the carrier.

[0013] The method for using the tilt-adjustable transfer trolley includes the following steps:

[0014] Step S1: Place the load to be transferred on the main body of the locking pallet, so that one side of the load abuts against the two sets of limiting seats to achieve the initial positioning of the load;

[0015] In step S2, the locking hole on the carrier automatically aligns with the pin block at the top of the locking push rod. The locking push rod is activated, and its movable part extends upward, causing the pin block to embed into the locking hole of the carrier, thus completing the locking and fixing of the carrier.

[0016] Step S3: According to the subsequent docking requirements, the hand crank of the transverse component is rotated. The hand crank drives the transmission rod to rotate through the transmission box. The transmission rod drives the lead screw sliding seat to move laterally along the deflection base plate. Since the lead screw sliding seat is engaged with the sliding sleeve seat, when the lead screw sliding seat moves laterally, it pushes the sliding sleeve seat to deflect, thereby driving the deflection frame and the top locking tray to deflect synchronously.

[0017] In step S4, during the deflection process, the support plate of the tilting support assembly swings along the support wheel under the drive of the deflection frame. The lateral limit wheel and the vertical limit wheel limit the support plate laterally to ensure smooth deflection.

[0018] Step S5: After the tilt angle is adjusted to the preset value, the pneumatic push rod is activated through the control box to extend its output end and press against the bottom of the deflection frame.

[0019] In step S6, the operator holds the push handle and pushes the main body of the transfer trolley to move towards the designated receiving module. The docking guide plate plays a guiding role, so that the deflectable support component is gradually aligned with the receiving module. When the docking auxiliary component contacts the bottom of the receiving module, the main body of the transfer trolley reaches the maximum movement position and stops moving.

[0020] Step S7: Then, the height of the deflectable support component is finely adjusted by the scissor lifting assembly to align the docking guide plate with the docking structure of the receiving module. When the contact sensor inside the docking guide plate contacts the receiving module, the contact sensor sends an alignment signal to complete the movement and alignment operation, and subsequent cargo transfer can be carried out.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. This invention effectively solves the core problem of limited angle and height adjustment in traditional transfer trolleys by optimizing the design of the deflectable support component and the scissor lifting component. With the help of the screw drive and hand crank operation of the lateral movement component, the deflection frame and locking tray can be flexibly driven to achieve precise angle deflection. Combined with the support wheel and limit wheel structure of the tilt support component, the deflection process is ensured to be smooth and without shaking. At the same time, the scissor lifting component can flexibly fine-tune the load-bearing height, and the pneumatic push rod tightens the support after the angle is set, further improving the structural stability. Ultimately, it achieves the adaptation to the different angle and height specifications of the receiving modules in different processes, completely avoiding the problem of goods transfer obstruction caused by angle or height mismatch, and significantly enhancing the versatility and adaptability of the transfer equipment under complex working conditions.

[0023] 2. This invention significantly improves the safety and docking accuracy of precision component transfer through the synergistic design of the locking tray and the precision docking structure. The limiting seat of the locking tray can achieve initial positioning of the load, and the locking push rod's pin block and the load's locking hole are nested and locked, effectively preventing the precision components from shifting or deviating during transfer and angle adjustment. The docking guide plate of the deflectable support component guides the alignment, the docking auxiliary component limits the maximum movement distance, and the contact sensor provides real-time feedback of the alignment signal, forming a precise docking process of "guidance-limiting-confirmation". This ensures the integrity and safety of the precision component transfer process, while shortening the docking time and helping to improve the overall production capacity and processing accuracy of the production line.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments, which illustrate the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0032] Example:

[0033] like Figures 1-6 As shown, the tilt-adjustable transfer trolley includes a transfer trolley module 1, a scissor lift assembly 2, a deflectable support assembly 3, and a locking pallet 4. The transfer trolley module 1 is used to support the scissor lift assembly 2, which is mounted on top of the transfer trolley module 1. The deflectable support assembly 3 is mounted on top of the scissor lift assembly 2 and is pushed by the scissor lift assembly 2. The locking pallet 4 is mounted on top of the deflectable support assembly 3 and is used to carry goods.

[0034] The transfer trolley module 1 includes a transfer trolley body 11, a push handle 12, a control box 13, and docking auxiliary components 14. The transfer trolley body 11 carries the push handle 12, the control box 13, and the docking auxiliary components 14. The push handle 12 is installed on the side of the transfer trolley body 11, the docking auxiliary components 14 are installed on one side of the top of the transfer trolley body 11, the scissor lift assembly 2 is installed on the other side of the top of the push handle 12, and the two sets of docking auxiliary components 14 are respectively installed at both ends of one side of the bottom of the push handle 12. Both sets of docking auxiliary components 14 are oriented towards the direction of travel of the transfer trolley body 11. The transfer trolley module 1 is used to drive the deflectable support component 3, the locking tray 4 and the goods carried on the locking tray 4 to transfer. The push handle 12 is used to push the transfer trolley body 11. When the transfer trolley body 11 moves to the designated position, the docking auxiliary component 14 is used to limit the maximum movable distance of the transfer trolley body 11. When the docking auxiliary component 14 contacts the bottom of the receiving module, the transfer trolley body 11 reaches the maximum movable position.

[0035] The deflectable support assembly 3 includes a deflection base plate 31, a lateral movement assembly 32, an inclined support assembly 33, pneumatic push rods 34, and a deflection frame 35. The deflection base plate 31 is fixed to the top of the scissor lift assembly 2. The lateral movement assembly 32 is installed at the center of the deflection base plate 31. Two sets of inclined support assemblies 33 are installed on the longitudinal sides of the deflection base plate 31, and several sets of pneumatic push rods 34 are installed at the top four corners of the deflection base plate 31. The deflection frame 35 is installed between the top of the lateral movement assembly 32 and the inclined support assembly 33. The locking tray 4 is fixed to the top of the deflection frame 35. When it is necessary to adjust the deflection angle of the locking tray 4, the deflection frame 35 is deflected by the lateral movement assembly 32. The inclined support assembly 33 plays a role in restricting and supporting the deflection frame 35 during the deflection process, thereby enabling the deflection frame 35 to achieve smooth and stable lateral deflection.

[0036] The output end of the pneumatic push rod 34 abuts against the bottom of the deflection frame 35. The pneumatic push rod 34 is electrically connected to the control box 13. The pneumatic push rod 34 is used to assist in supporting the deflection frame 35 and finely adjust its support height. After the deflection frame 35 completes the tilt angle adjustment, the output end of the pneumatic push rod 34 extends and presses against the deflection frame 35 to enhance the structural stability in the deflection state.

[0037] The lateral movement assembly 32 includes a lead screw slide seat 321, a transmission rod 322, a transmission box 323, a hand crank 324, and a sliding sleeve seat 325. The lead screw slide seat 321 is fixed at the center of the deflection base plate 31. The transmission rod 322 is horizontally installed in the middle of the deflection base plate 31, and the output end of the transmission rod 322 is connected to the input end of the lead screw slide seat 321. The transmission box 323 is installed at the end of the transmission rod 322. The hand crank 324 is vertically installed on the lateral side of the deflection base plate 31, and the end of the hand crank 324 is connected to the transmission box 323. The sliding sleeve seat 325 is installed on the deflection base plate 31 via a connecting plate. At the center of the skeleton 35 and at the center of the bottom of the sliding sleeve 325, it engages with the top of the lead screw sliding seat 321. When it is necessary to adjust the setting position of the deflection skeleton 35, the hand crank 324 is rotated. The hand crank 324 drives the transmission rod 322 to rotate through the transmission box 323. The transmission rod 322 drives the lead screw sliding seat 321 to move laterally. Since the lead screw sliding seat 321 and the sliding sleeve 325 are engaged, the lead screw sliding seat 321 drives the sliding sleeve 325 to deflect when it moves laterally. The deflection skeleton 35 performs synchronous deflection movement under the push of the sliding sleeve 325.

[0038] The tilting support assembly 33 includes a support base 331, support wheels 332, a support plate 333, a lateral limiting wheel 334, and a vertical limiting wheel 335. The support base 331 is fixed to the longitudinal side of the deflection base plate 31. Two sets of support wheels 332 are respectively installed on the left and right sides of the support base 331 via rotating shafts. The support plate 333 is placed between the two sets of support wheels 332, and the top of the support plate 333 is connected to both sides of the deflection frame 35 via connecting plates. A slot is opened at the center of the support plate 333, and the bottom of the slot is arc-shaped. The lateral limiting wheel 334 is installed on the front side of the support base 331 via a rotating shaft. At the middle position, the lateral limiting wheel 334 is nested in the slot, and the vertical limiting wheel 335 is installed at the middle position of the rear side of the support base 331 through the rotating shaft. When the deflection frame 35 swings under the drive of the lateral moving component 32, the bottom support plate 333 of the deflection frame 35 rotates between the two sets of support wheels 332 under the drive of the deflection frame 35. The lateral limiting wheel 334 and the vertical limiting wheel 335 play a lateral limiting role on the support plate 333. The support plate 333 can only swing between the two sets of support wheels 332. The deflection frame 35 tilts under the cooperation of the lateral moving component 32 and the tilting support component 33.

[0039] The deflectable support assembly 3 also includes a docking guide plate 36 and a contact sensor 37. A set of docking guide plates 36 are fixed on both sides of the deflection frame 35. The two sets of docking guide plates 36 are symmetrically arranged. The contact sensor 37 is located inside the docking guide plate 36. After reaching the designated position, the two sets of docking guide plates 36 achieve initial alignment with the receiving module. During the alignment process, the docking guide plate 36 can play an alignment guiding role, so that the deflectable support assembly 3 can be gradually aligned during further movement. When the contact sensor 37 contacts the receiving module, the contact sensor 37 sends a signal, which indicates that the deflectable support assembly 3 is in place.

[0040] The locking tray 4 includes a tray body 41, a locking push rod 42, and a limiting seat 43; the tray body 41 is fixed to the top of the deflection frame 35, the locking push rod 42 is installed at the center of one side of the tray body 41, and two sets of limiting seats 43 are respectively installed at both ends of one side of the tray body 41.

[0041] A pin block is installed on the top of the locking push rod 42. The pin block is used to lock the carrier after nesting with the carrier. When one side of the carrier abuts against the limiting seat 43, the locking hole of the carrier is aligned with the pin block. At this time, the movable part of the locking push rod 42 moves upward, and the pin block is inserted into the locking hole under the push of the locking push rod 42. The carrier keeps its position fixed under the restriction of the pin block and the locking hole. When it reaches the designated position and is ready to release the carrier, the locking push rod 42 drives the pin block to exit from the locking hole, releasing the restriction on the carrier. At this time, the carrier can move freely.

[0042] The method for using the tilt-adjustable transfer trolley includes the following steps:

[0043] Step S1: Place the load to be transferred on the pallet body 41 of the locking pallet 4, so that one side of the load abuts against the two sets of limiting seats 43, thereby achieving the initial positioning of the load.

[0044] In step S2, the locking hole on the carrier is automatically aligned with the pin block at the top of the locking push rod 42. The locking push rod 42 is activated, and its movable part extends upward, driving the pin block to embed into the locking hole of the carrier, thus completing the locking and fixing of the carrier.

[0045] Step S3: According to the subsequent docking requirements, the hand crank 324 of the transverse component 32 is rotated. The hand crank 324 drives the transmission rod 322 to rotate through the transmission box 323. The transmission rod 322 drives the lead screw sliding seat 321 to move laterally along the deflection base plate 31. Since the lead screw sliding seat 321 is engaged with the sliding sleeve seat 325, when the lead screw sliding seat 321 moves laterally, it pushes the sliding sleeve seat 325 to deflect, thereby driving the deflection frame 35 and the locking tray 4 on the top to deflect synchronously.

[0046] In step S4, during the deflection process, the support plate 333 of the inclined support assembly 33 swings along the support wheel 332 under the drive of the deflection frame 35. The lateral limiting wheel 334 and the vertical limiting wheel 335 laterally limit the support plate 333 to ensure smooth deflection.

[0047] Step S5: After the tilt angle is adjusted to the preset value, the pneumatic push rod 34 is activated through the control box 13, so that its output end extends and presses against the bottom of the deflection frame 35.

[0048] In step S6, the operator holds the push handle 12 and pushes the main body 11 of the transfer trolley to move towards the designated receiving module. The docking guide plate 36 plays a guiding role, so that the deflectable support component 3 is gradually aligned with the receiving module. When the docking auxiliary component 14 contacts the bottom of the receiving module, the main body 11 of the transfer trolley reaches the maximum movement position and stops moving.

[0049] Step S7: Then, the height of the deflectable support component 3 is finely adjusted by the scissor lifting component 2 so that the docking guide plate 36 is aligned with the docking structure of the receiving module. When the contact sensor 37 inside the docking guide plate 36 contacts the receiving module, the contact sensor 37 sends an alignment signal to complete the movement and alignment operation, and subsequent cargo transfer can be carried out.

[0050] The above description is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.

Its movable part extends upward, driving the pin block to embed into the locking hole of the carrier, thus completing the locking and fixing of the carrier. Step S3: According to the subsequent docking requirements, the hand crank (324) of the transverse component (32) is rotated. The hand crank (324) drives the transmission rod (322) to rotate through the transmission box (323).

The docking guide plate (36) plays a guiding role, so that the deflectable support component (3) gradually aligns with the receiving module. When the docking auxiliary component (14) contacts the bottom of the receiving module, the main body (11) of the transfer trolley reaches the maximum movement position and stops moving. Step S7: Then, the height of the deflectable support assembly (3) is finely adjusted by the scissor lifting assembly (2) so that the docking guide plate (36) is aligned with the docking structure of the receiving module. When the contact sensor (37) inside the docking guide plate (36) contacts the receiving module, the contact sensor (37) sends an alignment signal to complete the movement and alignment operation, and subsequent cargo transfer can be carried out.
