Description

Technical Field

[0001] The invention relates to the field of engineering vehicles, and in particular to an intelligent picking and placing lifting and transporting vehicle. Background Art

[0002] There are a large number of heavy equipment in mining operations. The transportation of such equipment is usually carried out by two types of transporters: frame transporters and forklifts. The former can only be used for transporting the brackets in the mine, which is very limited. The latter can be used for transporting and moving a variety of large equipment, which is highly practical. The forklift of the existing forklift has a fixed length. When transporting longer equipment, the length of the forklift is shorter than the bottom of the equipment, so that the bottom of the equipment is partially suspended. When the road surface inside the mine is uneven, the forklift will bump when it passes through the uneven road surface during transportation. The incomplete contact of the bottom of the equipment can easily cause the equipment to deviate or even fall. The space inside the mine is small, and it is extremely difficult to reload the equipment.

[0003] To transport extra-long equipment, two forklifts are currently needed to coordinate the front and back transportation. However, there are some bends on the mine route. During the transportation and turning process, the two ends of the equipment carried by the two forklifts are prone to relative deflection, causing the equipment to separate from the fork, resulting in the need to reload and adjust the position. The forklift itself and the equipment block the workers' vision. The two forklifts require workers to have a high degree of coordination for loading, which makes the reloading process cumbersome and inefficient. Summary of the invention

[0004] In order to overcome the shortcomings of existing forklifts, such as insufficient forklift length, incomplete contact of the bottom surface of the equipment, which can easily cause the equipment to shift or even fall, and the cumbersome and inefficient process of two forklifts cooperating in carrying, reloading and adjusting the position, the present invention provides an intelligent pick-and-place lifting and transporting vehicle.

[0005] The technical solution of the present invention is: a smart pick-and-place lifting and transporting vehicle, comprising a tractor and a working vehicle head; the tractor is connected to the working vehicle head; it also comprises a supporting shovel, a supporting plate, a screw rod, a sliding block, a supporting assembly and a locking assembly; a power frame is installed on the working vehicle head; the power frame is connected to the supporting shovel; the supporting shovel is divided into a vertical block and a horizontal block; all the supporting shovels are slidably connected to the supporting plate; a hydraulic motor is installed in each vertical block; a cylindrical groove is provided on each supporting shovel; a screw rod is rotatably connected in each cylindrical groove; the screw rod is fixedly connected to the corresponding hydraulic motor output shaft; the hydraulic motor drives the screw rod to rotate; a sliding block is installed on each screw rod; all the sliding blocks are clamped with the supporting plate; all the vertical blocks are connected with a supporting assembly for supporting the load; the supporting plate and the sliding block are connected with a locking assembly for locking the sliding block.

[0006] Preferably, the support assembly includes a pad block and a first elastic member; each supporting shovel is provided with a plurality of limit grooves; each vertical block is provided with a plurality of pad blocks; each pad block is provided with an arc-shaped portion on the lower side; each arc-shaped portion is provided with a slot; a connecting strip is fixedly connected to all the pad blocks; the connecting strip is made of a deformable material; the connecting strip is fixedly connected to the supporting plate; a first elastic member is connected to the inner side of each vertical block.

[0007] Preferably, the locking assembly includes a transverse pressure strip, a locking block and a locking strip; a transverse pressure strip is slidably connected to the upper side of the supporting plate; a number of pressure blocks are fixedly connected to the transverse pressure strip; each slider is provided with a locking block; the lower side of the locking block is a rough surface; each slider is symmetrically provided with a number of movable grooves; a reset block is slidably connected in each movable groove; the reset block is fixedly connected to the adjacent locking block; a second elastic member is fixedly connected to the lower side of each reset block; and a number of locking strips are fixedly connected to each transverse block.

[0008] Preferably, the upper side of the transverse pressure strip is arc-shaped to reduce friction with the bottom surface of the loading equipment.

[0009] Preferably, the lower side of the locking block and the upper side of the locking strip are both configured to be in matching serrated shapes.

[0010] Preferably, an auxiliary unloading system is also included, which includes a driving member, a screw, an auxiliary roller and a bevel gear; a plurality of driving members are installed in the support plate; each driving member output end is connected to a screw; a debris discharge groove is opened on the support plate; an auxiliary roller is rotatably connected in the debris discharge groove; a bevel gear is fixed on each side of the auxiliary roller; the bevel gear is meshed with the adjacent screw for transmission.

[0011] Preferably, a plurality of convex strips for moving crushed stone impurities are fixedly connected to the auxiliary roller.

[0012] Preferably, the auxiliary roller is made of rubber.

[0013] Preferably, a supporting system is also included, which includes a linear drive, a magnetic plate and a supporting ball; a plurality of linear drives are installed on the left and right sides of the supporting plate; a magnetic plate is fixedly connected to the telescopic ends of the linear drives on the same side; an alarm is arranged in the magnetic plate; a plurality of supporting balls are arranged on each magnetic plate; the diameter of the supporting ball is slightly larger than the thickness of the supporting plate; the supporting ball is made of magnetic material.

[0014] Preferably, the supporting balls are not smooth.

[0015] The present invention has the following advantages: the present invention realizes increasing the supporting distance forward by the supporting plate, and completely supporting the relatively long equipment, so as to avoid that part of the bottom surface of the equipment is not supported by the supporting plate, which causes the equipment carried by the supporting plate to deviate or even fall when the equipment encounters uneven road surface when driving in the mine;

[0016] The equipment is supported by the pads, and the weight of the equipment is transferred to the horizontal block to prevent the support plate from being out of contact with the horizontal block at a position lower than the upper surface of the support plate after the support plate is extended, so that the horizontal block cannot contact the lower surface of the equipment to support it, and the support plate only contacts the front part of the horizontal block, which reduces the contact surface and makes the contact surface of the two bear a large weight, which can easily lead to structural deformation and damage after long-term use.

[0017] The pads are covered on the upper side of the horizontal block to isolate the parts on the horizontal block from the outside world, so as to prevent impurities from flying in the mine environment from falling on the horizontal block and its parts during transportation, making the parts unusable;

[0018] The slider is locked by the lower side of the locking block contacting and engaging with the upper side of the locking strip, and the pulling force of the slider along the screw rod is dispersed and applied to the locking block and the locking strip, so as to prevent the slider from being subjected to the strong pulling force from the supporting plate. The pulling force is applied to the slider and the screw rod for a long time, which can easily cause damage to the screw rod related structure;

[0019] The auxiliary rollers rub against the bottom of the equipment, pushing the equipment to move and unload in the opposite direction of the support plate reset, thereby preventing the support plate from extending to fully carry the longer equipment, which will prevent the bottom of the equipment from contacting the ground for friction unloading;

[0020] The accumulated gravel impurities are moved by the convex strips and then discharged downward through the impurity discharge trough to prevent the gravel impurities from falling and accumulating between the impurity discharge trough and the auxiliary roller, affecting the rotation of the auxiliary roller;

[0021] After the support ball and the magnetic plate are separated, the alarm inside the magnetic plate will sound, informing the workers that the equipment has deflected, and reminding the workers to always pay attention to the deviation of the equipment;

[0022] The deviated equipment is supported by support balls so that there is still a certain space between the bottom of the equipment and the ground. The workers adjust the posture of the support plate and raise the support plate again to load the equipment again, avoiding the equipment deviation and separation from the support plate, causing contact with the ground, and the reloading process is cumbersome and inefficient.

DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below with reference to the accompanying drawings. Example 1

[0034] like Figure 1-Figure 6 As shown, a smart pick-and-place lifting and transporting vehicle comprises a tractor 1 and an operating head 2; the tractor 1 is connected to the operating head 2;

[0035] It also includes a supporting shovel 3, a supporting plate 4, a screw rod 5, a slider 6, a supporting assembly and a locking assembly; a power frame 2001 is installed on the work vehicle head 2; the power frame 2001 is connected to the supporting shovel 3; the supporting shovel 3 is divided into a vertical block 3a and a horizontal block 3b; all the supporting shovels 3 are slidably connected to the supporting plate 4; a hydraulic motor 101 is installed in each vertical block 3a; a cylindrical groove is opened on each supporting shovel 3; a screw rod 5 is rotatably connected in each cylindrical groove; the screw rod 5 is fixedly connected to the corresponding output shaft of the hydraulic motor 101; the hydraulic motor 101 drives the screw rod 5 to rotate; a slider 6 is installed on each screw rod 5; all the sliders 6 are commonly engaged with the supporting plate 4; the slider 6 drives the supporting plate 4 to translate along the screw rod 5; all the vertical blocks 3a are connected to the supporting assembly; the supporting plate 4 and the slider 6 are connected to the locking assembly.

[0036] The supporting assembly includes a pad block 7 and a first elastic member 102; two limiting grooves 3001 are provided on the upper side of each supporting shovel 3; a number of pad blocks 7 are arranged in each vertical block 3a; each pad block 7 is provided with an arc portion 7001 on the left and right parts; a slot 7002 is provided on each arc portion 7001; a connecting strip 7003 is fixedly connected to all pad blocks 7; the connecting strip 7003 is made of deformable material; the connecting strip 7003 is fixedly connected to the supporting plate 4; a first elastic member 102 is connected to the upper part of each vertical block 3a; the first elastic member 102 is a spring.

[0037] The locking assembly includes a transverse pressure strip 21, a locking block 22 and a locking strip 23; the transverse pressure strip 21 is slidably connected to the rear of the supporting plate 4; four pressure blocks 2101 are welded symmetrically on the lower side of the transverse pressure strip 21; each slider 6 is provided with a locking block 22; the lower side of the locking block 22 is a rough surface; each slider 6 is provided with two movable grooves 6001 symmetrically; a reset block 2201 is slidably connected in each movable groove 6001; the reset block 2201 is fixedly connected to the adjacent locking block 22; a second elastic member 2202 is fixedly connected to the lower side of each reset block 2201; the second elastic member 2202 is a spring; two locking strips 23 are welded on each transverse block 3b.

[0038] The upper side of the transverse pressure strip 21 is arc-shaped to reduce the friction with the bottom surface of the loading device.

[0039] The lower side of the locking block 22 and the upper side of the locking strip 23 are both configured to be in a matching sawtooth shape, so as to increase the locking friction force.

[0040] The shovel of an existing forklift truck is of fixed length. When transporting longer equipment, the length of the shovel board is shorter than the bottom of the equipment, causing part of the bottom of the carried equipment to be suspended in the air. When the road surface inside the mine is uneven and the forklift truck is bumpy during transportation, incomplete contact with the bottom of the equipment can easily cause the equipment to shift or even fall, and the space inside the mine is small, making it extremely difficult to reload the equipment.

[0041] The worker controls the working vehicle head 2 and related parts thereon by driving the tractor 1. When transportation is required, the tractor 1 is driven in front of the transportation equipment so that the working vehicle head 2 faces the equipment, and the power frame 2001 is controlled to make the supporting shovel 3 move downward and form a certain angle with the ground, so that the inclined surface of the front side of the supporting plate 4 is in contact with the ground, and the shoveling and loading operation is prepared. Then the worker starts the tractor 1 to move forward, and scoops up the equipment through the front side of the supporting plate 4 until the rear side of the equipment contacts the front side of the vertical block 3a, and then controls the supporting shovel 3 to make the supporting plate 4 lift the equipment upward off the ground. At this time, if the equipment is relatively long, part of the bottom surface of the equipment is still not supported by the supporting plate 4, which may easily cause the equipment to be bumped when encountering uneven roads when driving in the mine, causing the equipment carried by the supporting plate 4 to deviate or even fall. At this time, the hydraulic motor 101 is controlled to work to drive the screw rod 5 to rotate, and the slider 6 moves forward along the screw rod 5, pushing the supporting plate 4 to move forward and extend out, and reach the position as shown in the figure. Figure 3 In the state shown, the support plate 4 increases the supporting distance forward and fully supports the longer equipment, thereby preventing part of the bottom surface of the equipment from being unsupported by the support plate 4, causing the equipment carried by the support plate 4 to deviate or even fall when encountering uneven roads while traveling in the mine.

[0042] In addition, after the support plate 4 is extended, the part where the support plate 4 and the cross block 3b are out of contact is lower than the upper surface of the support plate 4, and the cross block 3b cannot contact the lower surface of the equipment to support it. At this time, the support plate 4 only contacts the front part of the cross block 3b, and the contact area is reduced, so that the contact surface of the two bears a greater weight, which can easily lead to structural deformation and damage after long-term use.

[0043] Furthermore, if Figure 4As shown, all the pads 7 are initially supported by the rear side of the supporting plate 4 and stored in the vertical block 3a, and the first elastic member 102 is in a compressed state. When the supporting plate 4 moves forward and extends, the pads 7 lose the restriction of the supporting plate 4, and at the same time, the supporting plate 4 pulls the connecting strip 7003, and the pads 7 are pushed out one by one under the action of the first elastic member 102, and extend together with the supporting plate 4. During the extension process, each pad 7 gradually changes from a vertical arrangement state to a horizontal arrangement state. In the horizontal state, the arc portion 7001 fits with the limiting groove 3001 and makes the pad 7 slide on the horizontal block 3b, and the clamping groove 7002 fits with the L-shaped limiting groove 3001, so that the pad 7 is clamped in the horizontal block 3b, to prevent the pad 7 from falling off from the cross block 3b during the movement of the vehicle; when the supporting plate 4 is extended into place, the pad 7 is extended immediately and closely arranged on the cross block 3b, and the upper surface of the pad 7 is at the same height as the upper surface of the supporting plate 4, so that the equipment is supported by the pad 7 and the weight of the equipment is transferred to the cross block 3b, to prevent the supporting plate 4 from being out of contact with the cross block 3b at a position lower than the upper surface of the supporting plate 4 after the supporting plate 4 is extended, and the cross block 3b cannot contact the lower surface of the equipment to support it, and the supporting plate 4 only contacts with the front part of the cross block 3b, the contact surface is reduced, and the contact surface between the two bears a larger weight, which is very likely to cause structural deformation and damage after long-term use.

[0044] In particular, when the cushion block 7 is extended, it covers the upper side of the horizontal block 3b, isolating the parts on the horizontal block 3b from the outside world, thereby preventing impurities flying from the mine environment from falling on the horizontal block 3b and its parts during transportation, rendering the parts unusable; when the support plate 4 is reset, the rear side of the support plate 4 will push the cushion block 7, and the cushion block 7 will compress the first elastic member 102, so that the cushion block 7 is retracted into the vertical block 3a and stored.

[0045] The forklift transport equipment is generally heavy equipment. During the transportation process, due to the inertia of the tractor 1, the slider 6 will be subjected to a strong pulling force from the support plate 4. The pulling force is applied to the slider 6 and the screw rod 5 for a long time, which can easily cause damage to the related structures of the screw rod 5. When the equipment is loaded on the support plate 4, the bottom surface of the equipment gradually contacts the upper inclined surface of the horizontal pressure bar 21, pressing the horizontal pressure bar 21 to move downward, and the horizontal pressure bar 21 drives the pressure block 2101 to move downward. The pressure block 2101 squeezes the corresponding locking block 22 to make it move downward, and the locking block 22 During the downward movement, the corresponding reset block 2201 is driven to move downward in the movable groove 6001 and squeeze the second elastic member 2202 to shrink it. When the locking block 22 is finally pressed into place, the lower side of the locking block 22 contacts and engages with the upper side of the locking strip 23 to lock the slider 6. At the same time, the pulling force of the slider 6 along the direction of the screw rod 5 is dispersed and applied to the locking block 22 and the locking strip 23, so as to prevent the slider 6 from being subjected to the strong pulling force from the supporting plate 4. The pulling force is applied to the slider 6 and the screw rod 5 for a long time, which can easily cause damage to the related structures of the screw rod 5.

[0046] When it is necessary to control the support plate 4 to reset, first control the support plate 4 to unload the equipment loaded thereon. At this time, the cross pressure bar 21 loses the pressure of the bottom surface of the equipment, and the above-mentioned related parts lose the pressure of the cross pressure bar 21. The second elastic member 2202 recovers and pushes the reset block 2201 to reset upward. The reset block 2201 drives the locking block 22 to move upward. During the upward movement of the locking block 22, the pressure block 2101 and the cross pressure bar 21 are pushed upward to reset. Finally, the locking block 22 is separated from the locking bar 23, unlocking the slider 6, so that the slider 6 can move normally along the screw rod 5 and then drive the support plate 4 to move and reset. Example 2

[0047] On the basis of Example 1, Figure 2 , Figure 4 ,and Figure 7 As shown, it also includes an unloading auxiliary system, which includes a driving member 201, a screw 202, an auxiliary roller 203 and a bevel gear 204; two driving members 201 are installed in the support plate 4; the driving member 201 is a motor; each output end of the driving member 201 is connected to a screw 202; a debris discharge groove 4001 is opened on the support plate 4; an auxiliary roller 203 is rotatably connected in the debris discharge groove 4001; a bevel gear 204 is welded on both sides of the auxiliary roller 203; the bevel gear 204 is meshed with the adjacent screw 202 for transmission.

[0048] A plurality of convex strips 20301 are welded on the auxiliary roller 203 .

[0049] The auxiliary roller 203 is made of rubber to increase friction.

[0050] When the forklift truck unloads, the friction between the bottom surface of the equipment and the ground, and the movement of the vehicle to lower the equipment, and the extension of the support plate 4 to fully support the longer equipment will prevent the bottom surface of the equipment from contacting the ground for friction unloading.

[0051] Therefore, when the support plate 4 is in the extended state and needs to be unloaded, the support plate 4 is controlled to move down close to the ground, and the driving member 201 is controlled to work. The driving member 201 drives the screw 202 to rotate, and the screw 202 then transmits the bevel gear 204, thereby driving the auxiliary roller 203 to rotate in the opposite direction of the support plate 4 reset. At this time, the top of the auxiliary roller 203 is flush with the upper surface of the support plate 4, and then the auxiliary roller 203 rubs against the bottom surface of the equipment. The surface of the auxiliary roller 203 is made of rubber material, which increases the friction with the bottom surface of the equipment, and pushes the equipment to move in the opposite direction of the support plate 4 reset to unload, thereby avoiding the support plate 4 from extending to achieve full bearing of longer equipment, and the bottom surface of the equipment will not be able to contact the ground for friction unloading.

[0052] Usually, the equipment is placed on the ground, and gravel impurities adhere to its bottom surface. When the supporting plate 4 carries the equipment, larger gravel impurities on the bottom surface of the equipment fall into the space between the impurity discharge groove 4001 and the auxiliary roller 203, affecting the rotation of the auxiliary roller 203. In response to this, during the rotation of the auxiliary roller 203, the convex strip 20301 rotates with the auxiliary roller 203, and pushes the gravel impurities to the bottom of the impurity discharge groove 4001, so that the gravel impurities are finally discharged downward through the impurity discharge groove 4001, thereby preventing the gravel impurities from falling into the space between the impurity discharge groove 4001 and the auxiliary roller 203 and accumulating, affecting the rotation of the auxiliary roller 203. Example 3

[0053] On the basis of Example 2, Figure 2 and Figure 8-Figure 9 As shown, it also includes a supporting system, which includes a linear drive 301, a magnetic plate 302 and a supporting ball 303; the magnetic plate 302 and the supporting ball 303; two linear drives 301 are installed on the left and right sides of the supporting plate 4; the linear drive 301 is an electric push rod; a magnetic plate 302 is fixedly connected to the telescopic end of the linear drive 301 on the same side; an alarm is arranged in the magnetic plate 302; each magnetic plate 302 is provided with at least two supporting balls 303; the diameter of the supporting ball 303 is slightly larger than the thickness of the supporting plate 4; the supporting ball 303 is made of magnetic material.

[0054] The support ball 303 is not smooth and is used to increase the friction when contacting the ground and the bottom surface of the device to prevent the device from moving.

[0055] For the transportation of extra-long equipment, two forklifts are currently needed to cooperate in front and back transportation. However, there are some bends in the mine route. During the transportation and turning process, the two ends of the equipment carried by the two forklifts are prone to relative deflection, causing the equipment to separate from the support plate 4 and fall to the ground, resulting in the need to adjust the position and reload. The forklift itself and the obstruction of the equipment block the workers' vision. The two forklifts require workers to have a high degree of coordination for loading, which makes the reloading process cumbersome and inefficient.

[0056] The initial state of the magnetic plate 302 and the support ball 303 is as follows Fig. 9 As shown, after the supporting plate 4 carries the equipment, the linear actuator 301 is controlled to extend upward, driving the magnetic plate 302 and the supporting ball 303 to move upward, so that the top of the supporting ball 303 is higher than the upper surface of the supporting plate 4. At this time, the supporting ball 303 is at a certain distance from the ground. When the two forklifts turn the equipment, the equipment deviates to one side relative to the supporting plate 4 and leaves the supporting plate 4. Fig. 9As a direction reference, the equipment deviates and contacts the right side of the support ball 303, pushing the support ball 303 to move to the left and separate from the magnetic plate 302. After the support ball 303 and the magnetic plate 302 are separated, the alarm in the magnetic plate 302 sounds, informing the worker that the equipment is deflected at this time, reminding the worker to always pay attention to the deviation of the equipment; at the same time, after the support ball 303 is separated from the magnetic plate 302, the support ball 303 is at a certain distance from the ground and will fall under the equipment. At this time, if the worker needs to adjust the position of the support plate 4, the support plate 4 can be put down. At this time, because the diameter of the support ball 303 is greater than the thickness of the support plate 4, the support ball 303 replaces the support plate 4 to support the equipment, and the support ball 303 is not smooth. The surface is used to increase the friction when contacting with the ground and the bottom of the equipment to prevent the equipment from moving. At the same time, the support ball 303 allows a certain space between the bottom of the equipment and the ground. Then the worker adjusts the posture of the support plate 4 through the tractor 1, and then lifts the support plate 4 again to carry the equipment again, so as to avoid the equipment from deviating and separating from the support plate 4 to cause contact with the ground, and the reloading process is cumbersome and inefficient. When the support plate 4 is reloaded with the equipment, if the detached support ball 303 and the magnetic plate 302 are close to each other, they will be re-adsorbed on the magnetic plate 302 under the action of its magnetic attraction. If the distance is far, it can be re-adsorbed on the magnetic plate 302 through manual intervention, which can still play a role in subsequent transportation.

[0057] In addition, when the support ball 303 is adsorbed on the magnetic plate 302 again, the linear drive 301 is controlled to drive the magnetic plate 302 to reset downward. At this time, the lower side of the support ball 303 is in contact with the ground and is squeezed by the ground. Relative to the downward moving magnetic plate 302, the support ball 303 slides upward, so that the height of the support ball 303 is located in the middle of the magnetic plate 302. After the relative position of the support ball 303 and the magnetic plate 302 is adjusted, the linear drive 301 is controlled again to drive the magnetic plate 302 to extend upward, so that the top of the support ball 303 is higher than the upper surface of the support plate 4, which is convenient for the next support work.
