Description

Technical Field

[0001] The present invention relates to a lifting device for a three-dimensional garage, and more specifically to a screw-type one-machine multi-board driving device for a three-dimensional garage. Background Art

[0002] As an important facility to relieve the urban parking pressure, underground parking lots have been widely used in cities in recent years. However, with the continuous increase in the number of automobiles in large and medium-sized cities, the planning and construction speed of parking spaces far lags behind the growth rate of the number of automobiles. Therefore, the problem of difficult parking in large and medium-sized cities is still intensifying year by year. To alleviate the problem of difficult parking, technicians in this field have designed multi-layer parking devices with parking brackets that can be lifted. The parking brackets of such parking devices can be lifted. When storing and retrieving vehicles, the upper parking brackets can be lowered to the first floor for vehicles to enter and exit, which can effectively increase the number of parking spaces in the parking lot. All existing such parking devices on the market are equipped with independent lifting drive devices on each liftable parking bracket to drive the lifting of each parking bracket, and the equipment cost is relatively high. To reduce the cost of the lifting drive device of the three-dimensional garage, the inventor has designed a one-machine multi-board drive structure that uses a set of mobile rotary rods to cooperate with multiple drums to wind and unwind steel wires to realize the lifting of each lifting bracket. This structure can control the lifting of multiple parking brackets by one lifting motor. However, there is a dead angle in the cooperation between the lateral movement of the rotary rod and the rotation of the drum. Precise positioning is required between the drum and the rotary rod, and a relatively complex avoidance structure for preventing the rotary rod from jamming with the drum and an avoidance program for releasing jamming are set. Therefore, during installation, the cooperation position between the drum and the rotary rod needs to be debugged repeatedly for many times, and during the operation of the garage, the cooperation position and control program also need to be calibrated regularly. Otherwise, the problem of the rotary rod jamming with the drum may occur, resulting in the inability of the parking bracket to be lifted and lowered normally. Summary of the Invention

[0003] The object of the present invention is to provide a screw-type one-machine multi-board driving device for a three-dimensional garage, which can enable multiple liftable parking brackets in the three-dimensional garage to share a set of lifting drive devices, significantly reduce the equipment cost of the garage itself, the parking brackets are driven by a mobile screw rod, the connection and separation between the lifting device and the parking brackets do not require precise positioning, and the phenomenon of jamming will not occur. The structure and control program are simple, and it can operate stably for a long time.

[0004] To achieve the above object, the present invention is realized through the following technical solutions: It includes a parking frame. Multiple upper parking spaces are arranged side by side at the upper part of the parking frame. A liftable lifting bracket is arranged in each upper parking space. An anti-falling device is arranged between each lifting bracket and the parking frame. The anti-falling device can fix each lifting bracket in the lifting position. Above one end of the parking frame, an upper track is arranged, and a lower track is arranged below the upper track. A walking frame is installed between the upper track and the lower track. The upper and lower ends of the walking frame are respectively matched with the upper track and the lower track. A walking wheel driven by a walking motor is installed on the walking frame. The walking wheel can drive the walking frame to move horizontally along the upper track and the lower track. A vertical lead screw is installed on the walking frame.

A vertical guide block is installed on the nut. The vertical guide block is matched with the vertical guide rail. A lifting limit block is installed on the nut or the vertical guide block. At one end of each lifting bracket close to the walking frame, a lifting cross frame is arranged. The lifting cross frame can lift along the height direction of the parking frame. At least two groups of fixed pulleys are arranged on each side of the parking frame on both sides of each lifting bracket. At least two groups of lifting steel wires are arranged on both sides of each lifting bracket. Each lifting steel wire bypasses a fixed pulley at its corresponding position and then is connected to the lifting cross frame. When the lifting cross frame lifts, it can drive the lifting bracket to descend and rise through the lifting steel wire. When the walking frame moves horizontally, the lifting limit block can reach above each lifting cross frame and block the upward movement of the lifting cross frame. Lifting guide rails are arranged on the parking frame at both ends of the lifting cross frame. The two ends of the lifting cross frame are matched with the lifting guide rails. The lifting guide rails play a guiding role in the lifting of the lifting cross frame. On the side of the parking frame close to the walking frame, columns made of I-beams are arranged on both sides of each upper parking space. The grooves formed by the upper and lower flanges and the web on both sides of the I-beam are the lifting guide rails. Guide wheels are arranged at both ends of the lifting cross frame. The guide wheels are matched with the grooves on the side of the column. An upper cross frame is arranged at the upper end of the walking frame, and a lower cross frame is arranged at the lower end of the walking frame. The upper and lower ends of the walking frame are respectively connected to the middle parts of the upper cross frame and the lower cross frame. Guide wheels are arranged at positions close to both ends of the upper cross frame and positions close to both ends of the lower cross frame. The guide wheels on the upper cross frame and the guide wheels on the lower cross frame are respectively matched with the upper track and the lower track. The walking motor and the walking wheel are both installed on the lower cross frame on one side of the walking frame. A counterweight block is arranged on the lower cross frame on the other side of the walking frame. Both the upper track and the lower track are made of angle steel. Guide seats are installed on both the upper cross frame and the lower cross frame. Grooves are opened on the guide seats. Guide balls are installed in the grooves.

Through holes are opened at the bent parts of the angle steel of the upper cross frame and the lower cross frame. The guide seats are installed in the concave surfaces of the angle steel at the through holes of the upper cross frame and the lower cross frame. The guide balls of each guide seat pass through the corresponding through holes and contact the two inner inclined surfaces of the angle steel of the upper track or the lower track. A threaded hole is opened on the back of the guide seat, and the threaded hole communicates with the groove. An adjusting block is installed in the threaded hole. The outer periphery of the adjusting block is matched with the threaded hole by threads, and the end of the adjusting block contacts each ball. The anti-falling device includes vertical shafts arranged on the storage frames on both sides of each upper storage space. At least two groups of vertical shafts are arranged on the storage frames on both sides of each upper storage space. A transmission gear and a horizontal support plate are installed on each vertical shaft. The transmission gear can drive the horizontal support plate to rotate horizontally through the vertical shaft. A driving rack is arranged on one side of each transmission gear. The driving rack meshes with the transmission gear. A first connecting rod is installed between the driving racks at the same side position of the storage frame. An electric push rod is installed on the storage frame. The piston rod of the electric push rod is connected to the first connecting rod through a second connecting rod. When the piston rod of the electric push rod expands and contracts, it can drive each driving rack to move synchronously through the second connecting rod and the first connecting rod, so that each transmission gear rotates synchronously under the drive of the driving rack, thereby driving each horizontal support plate to switch between the state of coinciding with the storage frames on both sides of the upper storage space and protruding into the upper storage space. Slots are arranged above each lifting cross frame. An insertion plate is arranged at the bottom of the lifting limit block. When the lifting limit block contacts the top surface of each lifting cross frame, the insertion plate can be inserted into the slot of the corresponding lifting cross frame.

[0005] The advantages of the present invention are as follows: A set of lifting drive devices can be shared by multiple liftable storage brackets in the three-dimensional garage, significantly reducing the equipment cost of the garage itself. The storage brackets are driven by mobile lead screws. The connection and separation between the lifting device and the storage brackets do not require precise positioning, and there will be no jamming phenomenon. The structure and control program are simple, and it can operate stably for a long time, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The screw - type multi - plate drive device for a three - dimensional garage according to the present invention includes a parking frame 1. A plurality of upper parking spaces are arranged side by side at the upper part of the parking frame 1. Lifting brackets 4 capable of lifting are arranged in each of the upper parking spaces. An anti - falling device is arranged between each lifting bracket 4 and the parking frame 1, and the anti - falling device can fix each lifting bracket 4 at the lifting position. Above one end of the parking frame 1, an upper track 101 is arranged, and a lower track 102 is arranged below the upper track 101. A walking frame 103 is installed between the upper track 101 and the lower track 102. The upper and lower ends of the walking frame 103 are respectively matched with the upper track 101 and the lower track 102. A walking wheel 105 driven by a walking motor 104 is installed on the walking frame 103, and the walking wheel 105 can drive the walking frame 103 to move horizontally along the upper track 101 and the lower track 102. A vertical screw 106 is installed on the walking frame 103. The vertical screw 106 is connected to the output shaft of a lifting drive motor 107. A nut 108 is installed on the vertical screw 106. A vertical guide rail 109 is arranged on the walking frame 103. A vertical guide block 110 is installed on the nut 108, and the vertical guide block 110 is matched with the vertical guide rail 109. A lifting limit block 111 is installed on the nut 108 or the vertical guide block 110. At one end of each lifting bracket 4 close to the walking frame 103, a lifting cross - frame 112 is arranged, and the lifting cross - frame 112 can lift along the height direction of the parking frame 1. At least two groups of fixed pulleys 3 are arranged on each side of the parking frame 1 on both sides of each lifting bracket 4, and at least two groups of lifting steel wires 5 are arranged on each side of each lifting bracket 4. Each lifting steel wire 5 bypasses a fixed pulley 3 at its corresponding position and then is connected to the lifting cross - frame 112. When the lifting cross - frame 112 lifts, it can drive the lifting bracket 4 to descend and ascend through the lifting steel wire 5. When the walking frame 103 moves horizontally, the lifting limit block 111 can reach above each lifting cross - frame 112 to block the upward movement of the lifting cross - frame 112.

[0008] When each lifting bracket 4 is located in the upper parking space, the anti-falling device fixes each lifting bracket 4 in the lifting position. When a certain lifting bracket 4 needs to descend, the traveling motor 104 drives the traveling frame 103 to move to the position of the lifting cross frame 112 corresponding to this lifting bracket 4 through the traveling wheels 105; then the lifting drive motor 107 drives the lifting limit block 111 to descend through the vertical lead screw 106 and the nut 108 until it contacts the top surface of this lifting cross frame 112; at this time, the anti-falling device releases the fixation of the position of this lifting bracket 4, and the gravity of the lifting bracket 4 is converted into an upward pulling force applied to the lifting cross frame 112 after being reversed by the hoisting steel wire rope 5 and the fixed pulley 3. However, since the top of the lifting cross frame 112 is blocked by the lifting limit block 111, this lifting bracket 4 will not fall at this time; after the anti-falling device releases the fixation of the position of this lifting bracket 4, the lifting drive motor 107 drives the lifting limit block 111 to slowly rise through the vertical lead screw 106 and the nut 108, and the lifting cross frame 112 rises together with the lifting limit block 111 under the action of the upward pulling force until this lifting bracket 4 is lowered to the vehicle entry and exit position on the lower ground or platform; at this time, this lifting bracket 4 can stay in the vehicle entry and exit position waiting for the vehicle to drive in or out, and the traveling frame 103 can leave the position of this lifting bracket 4 and move to other lifting brackets that need to be lifted for driving.

[0009] When a certain lifting bracket 4 needs to rise, the lifting drive motor 107 drives the lifting limit block 111 to rise above the height of the corresponding lifting cross frame 112 of the lifting bracket 4 through the vertical lead screw 106 and the nut 108. Then, the traveling motor 104 drives the traveling frame 103 to move to the position of the corresponding lifting cross frame 112 of the lifting bracket 4 through the traveling wheels 105. The lifting drive motor 107 drives the lifting limit block 111 to descend through the vertical lead screw 106 and the nut 108, and pushes the lifting cross frame 112 to move downward. During the downward movement of the lifting cross frame 112, the lifting bracket 4 is pulled up through the hoisting wire rope 5 and the fixed pulley 3. When the lifting bracket 4 reaches the lifting position of the upper parking space, the anti-falling device corresponding to the lifting bracket 4 is activated to fix the lifting bracket 4 at the lifting position. At this time, the traveling frame 103 can leave the position of the lifting bracket 4 and move to other lifting brackets that need to be lifted for driving. The parking bracket of the screw type one-machine multi-board drive device of the three-dimensional garage described in the present invention is driven by a movable lead screw. As long as the lifting limit block 111 on the traveling frame 103 reaches above the lifting cross frame 112, the driving can be completed. Since the width of the existing three-dimensional parking space is at least more than 2 meters, the length of the lifting cross frame 112 can be completely equal to or longer than the width of the three-dimensional parking space. Therefore, there is a large fitting allowance between the lifting limit block 111 on the traveling frame 103 and the lifting cross frame 112, and precise positioning is not required at all. The combination and separation between the lifting limit block 111 and the lifting cross frame 112 are realized by driving the lifting limit block 111 to rise and fall by the nut 108. During the combination and separation process, no structure blocks the rising and falling of the lifting limit block 111, and the phenomenon of jamming will not occur. Therefore, the structure and control program of the present invention are simple and efficient, and can operate stably for a long time. The upper and lower ends of the traveling frame 103 are guided by tracks, which can prevent the traveling frame 103 from tilting. Therefore, the traveling frame 103 does not need to be provided with an anti-tilting base with a large floor area, which is beneficial to improving the space utilization rate of the parking area.

[0010] In order to prevent the lifting cross frame 112 from shifting in position or angle during the lifting and lowering process, resulting in the tilting or out-of-control of the lifting bracket 4, the present invention can be provided with lifting guide rails 113 on both ends of the lifting cross frame 112 in the parking frame 1. The two ends of the lifting cross frame 112 are matched with the lifting guide rails 113, and the lifting guide rails 113 play a guiding role in the lifting and lowering of the lifting cross frame 112. The lifting guide rails 113 can be independently provided guide rails, or the columns of the parking frame 1 can be directly used as guide rails. For example: on the side of the parking frame 1 close to the traveling frame 103, columns 115 made of I-beams are provided on both sides of each upper parking space. The grooves formed by the upper and lower flanges and the web on both sides of the I-beam are the lifting guide rails 113. Guide wheels 114 are provided at both ends of the lifting cross frame 112, and the guide wheels 114 are matched with the grooves on the side of the column 115.

[0011] In order to improve the stability of the walking frame 103 during movement, an upper cross-frame 116 can be provided at the upper end of the walking frame 103, and a lower cross-frame 117 can be provided at the lower end of the walking frame 103. The upper and lower ends of the walking frame 103 are respectively connected to the middle parts of the upper cross-frame 116 and the lower cross-frame 117. Guide wheels are provided at positions near the two ends of the upper cross-frame 116 and the lower cross-frame 117. The guide wheels of the upper cross-frame 116 and the guide wheels of the lower cross-frame 117 are respectively matched with the upper track 101 and the lower track 102. This structure can enable the walking frame 103 to form an "I"-shaped structure, increase its stability during lateral movement, and reduce the inclination and vibration of the walking frame 103 during movement due to its too narrow width. The above structure does not occupy the space outside the garage, so it will not affect the space utilization rate.

[0012] In order to further improve the stability of the walking frame 103 during movement, the following structure can also be adopted: The walking motor 104 and the walking wheels 105 are both installed on the lower cross-frame 117 on one side of the walking frame 103, and a counterweight 118 is provided on the lower cross-frame 117 on the other side of the walking frame 103. The counterweight 118 can balance the weights of the walking motor 104 and the walking wheels 105, make the weights on both sides of the walking frame 103 basically the same, and eliminate the uneven force during the reciprocating movement of the walking frame 103.

[0013] The upper track 101 and the lower track 102 of the present invention can adopt various forms of tracks, such as T-shaped tracks, etc. The preferred track structure is: The upper track 101 and the lower track 102 are both made of angle steel. Guide seats 127 are installed on the upper cross-frame 116 and the lower cross-frame 117. Grooves 119 are opened on the guide seats 127, and guide balls 120 are installed in the grooves 119. The guide balls 120 can simultaneously contact the two inner inclined surfaces of the angle steel of the upper track 101 or the lower track 102. A plurality of balls 121 are arranged along the circumference of the groove 119 inside the groove 119, and each ball 121 contacts the guide ball 120. When the guide ball 120 of this structure moves, it does not directly contact the bottom end of the track, and a part of the area for accommodating sundries can be left at the bottom end of the track. Small sundries falling into the track will not directly affect the operation of the balls, which can effectively extend the cleaning cycle of the track, reduce the maintenance cost, and the guide ball 120 is in rolling fit with both sides of the track and can automatically align to the center position. The guide ball 120 contacts the balls 121 inside the guide seat 127, and each ball 121 is arranged in a ring to support the guide ball 120 and can significantly reduce the cooperation resistance between the guide ball 120 and the guide seat 127. Compared with the existing track structure, the noise and resistance during operation can be effectively reduced.

[0014] In order to reduce the gap between the upper and lower cross frames and the upper and lower tracks, the upper cross frame 116 and the lower cross frame 117 can also be made of angle steel. The convex surface of the angle steel of the upper cross frame 116 corresponds and cooperates with the concave surface of the angle steel of the upper track 101, and the convex surface of the angle steel of the lower cross frame 117 corresponds and cooperates with the concave surface of the angle steel of the lower track 102. Through holes 122 are opened at the bent portions of the angle steels of the upper cross frame 116 and the lower cross frame 117. The guide seats 127 are installed in the concave surfaces of the angle steels at the through holes 122 of the upper cross frame 116 and the lower cross frame 117. The guide balls 120 of the guide seats 127 pass through the corresponding through holes 122 and contact the two inclined surfaces on the inner side of the angle steel of the upper track 101 or the lower track 102. This structure enables the upper and lower cross frames and the upper and lower tracks to operate with only a tiny fitting gap, further enhancing the stability of the walking frame 103. Moreover, when the guide balls 120 are accidentally broken or fall off, it can still ensure that the upper and lower cross frames and the upper and lower tracks will not separate, preventing the walking frame 103 from tipping over.

[0015] In order to adjust the gap between the upper and lower cross frames and the upper and lower tracks, screw holes 123 can be opened on the back surface of the guide seats 127. The screw holes 123 communicate with the grooves 119. Adjusting blocks 124 are installed in the screw holes 123. The outer periphery of the adjusting blocks 124 is in threaded cooperation with the screw holes 123, and the end portions of the adjusting blocks 124 contact the balls 121. When the gap needs to be adjusted, the adjustment can be carried out by rotating the adjusting blocks 124.

[0016] The anti-falling device described in the present invention can adopt various structures. For example, a bolt driven by an electric push rod is arranged on the vehicle storage frames 1 on both sides of each upper-layer vehicle storage space. Among them, the preferred structure is as follows: The anti-falling device includes vertical shafts 201 arranged on the vehicle storage frames 1 on both sides of each upper-layer vehicle storage space. At least two groups of vertical shafts 201 are arranged on the vehicle storage frames 1 on both sides of each upper-layer vehicle storage space. A transmission gear 202 and a horizontal support plate 203 are installed on each vertical shaft 201. The transmission gear 202 can drive the horizontal support plate 203 to rotate horizontally through the vertical shaft 201. A driving rack 204 is arranged on one side of each transmission gear 202. The driving rack 204 meshes with the transmission gear 202. A first connecting rod 205 is installed between the driving racks 204 at the same side position of the vehicle storage frame 1. An electric push rod 206 is installed on the vehicle storage frame 1. The piston rod of the electric push rod 206 is connected to the first connecting rod 205 through a second connecting rod 207. When the piston rod of the electric push rod 206 expands and contracts, it can drive each driving rack 204 to move synchronously through the second connecting rod 207 and the first connecting rod 205, so that each transmission gear 202 rotates synchronously under the drive of the driving rack 204, thereby driving each horizontal support plate 203 to switch between the state of coinciding with the vehicle storage frames 1 on both sides of the upper-layer vehicle storage space and protruding into the upper-layer vehicle storage space. The above structure connects the actions of each horizontal support plate 203 into one body through the first connecting rod 205 and the second connecting rod 207, and is jointly driven by the electric push rod 206. The anti-falling and unlocking actions of each horizontal support plate 203 are completed synchronously, which has the advantages of convenient control and rapid response.

[0017] Among them, the electric push rod 206 serves as a reciprocating driving mechanism for driving the driving rack 204 to move, which is convenient for installation on the vehicle frame 1 and for its later maintenance and repair. The reciprocating driving mechanism can also be that an electric motor drives an eccentric wheel to rotate, a driving rod is installed on the eccentric wheel, the driving rod is located in a guide groove, and the driving rod is connected to the driving rack 204 through the second connecting rod 207 and the first connecting rod 205. When the electric motor starts, it can drive the driving rack 204 to move.

[0018] In order to prevent the lifting cross frame 112 from disengaging from the lifting limit block 111 during the lifting process of the lifting bracket 4 in the present invention, a slot 125 can be arranged above each lifting cross frame 112, and a plug board 126 is arranged at the bottom of the lifting limit block 111. When the lifting limit block 111 contacts the top surface of each lifting cross frame 112, the plug board 126 can be inserted into the slot 125 of the corresponding lifting cross frame 112. The width of the slot 125 can be much larger than the width of the plug board 126. Therefore, there will still be a large fitting allowance between the lifting limit block 111 and the lifting cross frame 112.
