Example one

The present embodiment provides a corpse receiving and transporting device (abbreviated as receiving and transporting device), as shown in fig. 1-5, in a preferred embodiment of the present invention, the device comprises a loading plate 10 for placing corpses, a power track 20 installed below the loading plate 10 and capable of walking on the ground and stairs, and a power wheel 50 installed at the front end of the loading plate 10 and capable of walking on the ground. The length and the width of loading board 10 can set up according to reality (for example the length of loading board 10 can be 2 meters, and the width is 0.7 meter), and the front end of loading board 10 is equipped with preceding baffle 11, can prevent remains roll-off loading board 10 when loading board 10 inclines, and the both sides of the rear end of loading board 10 respectively are provided with a handle 12. The power caterpillar 20 is arranged below the rear part of the loading plate 10 and is parallel to the loading plate 10, the power caterpillar 20 can run on two steps at least at the same time, the number of the power caterpillar 20 is two, the two power caterpillar 20 are arranged symmetrically left and right and work synchronously, the power caterpillar 20 is the prior art, and the structure and the principle of the power caterpillar 20 are not detailed herein.

In this embodiment, a mounting seat 51 is fixed below the front end of the carrying plate 10, a power wheel 50 is mounted on the mounting seat 51, and the power wheel 50 rotates on the ground or on the receiving vehicle to move the receiving device forward. The specific power wheel 50 can be a power wheel 50 which is driven by a person to push the bearing plate 10 forward to enable the power wheel 50 to rotate on the ground or the receiving vehicle, or the power wheel 50 is driven by a driving mechanism to rotate, and when the power wheel 50 is driven by the driving mechanism, the power wheel 50 is a driving wheel which is the prior art, such as the driving wheel disclosed in CN98806804.4 or the omnidirectional driving wheel disclosed in CN 201810859152.5. The number of the power wheels 50 is one or two, and two power wheels 50 are preferably provided. When the number of the power wheels 50 is one, the power wheels 50 are balance wheels; when the number of the power wheels 50 is two, the axes of the two power wheels 50 are collinear, and the two power wheels 50 are connected through a differential mechanism to realize turning, which is not detailed herein for the prior art.

As shown in fig. 5, when the power track 20 walks on the ground, the lower end of the power wheel 50 is higher than the lower end of the power track 20, i.e., the power wheel 50 does not land. As shown in fig. 3 and 4, when the power track 20 walks on stairs, the power wheels 50 do not contact the stairs. As shown in fig. 1 and 2, when the power wheels 50 walk on the ground to make the pick-up travel straight or turn on the ground, the loading plate is inclined and the power track 20 is not in contact with the ground.

Preferably, the lower end of the carrier plate 10 is also mounted with a resistance track 30, the resistance track 30 being located on the front or rear side of the power track 20, preferably the front side of the resistance track 30 on the power track 20, and the power wheels 50 on the front side of the resistance track 20. The resistance crawler 30 is a crawler that generates frictional resistance, has no power, and cannot drive the receiving and conveying device to operate. The number of the resistance caterpillar tracks 30 is also two, and the two resistance caterpillar tracks 30 are symmetrically arranged left and right. The resistance crawler 30 is connected to the loading plate 10 by a lifting mechanism (which is a second lifting mechanism 45), and the lower surface of the resistance crawler 30 can be flush with the lower surface of the power crawler 20; when the remains receiving and transporting device turns, the resistance crawler 30 is not in contact with the ground.

Preferably, when only power track 20 is provided, the length of power track 20 spans at least three step apexes; when both the power track 20 and the resistance track 30 are provided, the power track 20 and the resistance track 30 meet flush (do not interfere with each other when running) and have an overall length that spans at least three step apexes. Through the length of the crawler belt, the length of the crawler belt at least spans the top points of the three steps, and the crawler belt can be guaranteed not to be blocked smoothly when going down stairs.

When the transporting device is used for transporting the remains, the remains are lifted to the bearing plate 10, as shown in fig. 1, the bearing plate 10 is inclined, the power wheel 50 is in contact with the ground, the power crawler 20 and the resistance crawler 30 are not in contact with the ground, one or two persons for transporting hold the handle 12 by hands to assist the operation of the transporting device, then the power wheel 50 is rotated on the ground, the transporting device 50 advances on a corridor (passageway of a floor), and when the transporting device needs to turn, the power wheel 50 drives the carrying plate to turn or the person assists to rotate the bearing plate 10 to turn. In addition, when the vehicle travels straight on the ground, the power crawler 20 may be used to drive the receiving and transporting apparatus to travel on the ground, and when the vehicle turns, the power wheels 50 may be switched to contact with the ground to turn the vehicle.

In order to facilitate the auxiliary operation of the receiving means by the receiving person when going downstairs, as shown in fig. 6, the handle 12 is a long handle and can be retracted or extended into the loading plate 10, and when going downstairs, the handle 12 is pulled out (the handle 12 can not be rotated after the handle 12 is pulled out, so that the angle of the loading plate 10 with the horizontal plane or the vertical plane can be adjusted by operating the handle 12), so as to facilitate pulling the receiving means, and prevent the receiving means from falling down; when walking on the ground, the handle 12 is retracted into the carrier plate 10 as shown in fig. 1.

When the receiving device is moved to the place of the stairs, as shown in fig. 7, the receiving person holds the handle 12 and rotates up and down to adjust the angle of the loading plate 10, so that the front end of the power crawler 20 lands on the ground, and then pushes the receiving device forward, so that the power wheel 50 is suspended on the stairs. As shown in fig. 8, the resistance track 30 is then lowered downwardly to height by the second lifting mechanism 45, the resistance track 30 descending onto the staircase and contacting the step apex (i.e. the intersection of the staircase step face and the staircase riser projecting outwardly). As shown in fig. 9, the second lift mechanism 45 then continues to operate, increasing the distance between the resistance track 30 and the carrier plate 10, raising the carrier plate 10, the carrier plate 10 raising the power track 20 off the ground, making the resistance track 30 level with the power track 20, and then raising the interface slightly upward reduces the contact area with the step apex, reducing resistance. The interface is then pushed forward as shown in fig. 10, causing the power track 20 to also contact the step apex, and then the power track 20 is operated, the power track 20 causing the interface to travel down the stairs. When the receiving and transporting device goes down stairs, the resistance crawler 30 plays a role of resistance, the falling force of the receiving and transporting device which descends is reduced, the pulling force of a person pulling the receiving and transporting device is reduced, and the labor intensity of the person is reduced.

When the pick-up device is lowered to the landing at the end of the staircase, as shown in figure 11, the resistance crawlers 30 are retracted upwardly by the second lifting mechanism 45, the resistance crawlers 30 clear the tops of the steps to empty, and the power crawlers 20 operate to continue the pick-up device down the staircase until the power wheels 50 contact the landing. The pick-up is then lifted slightly upwards to empty the powered crawler 20 from the step apex and the pick-up can then be turned to the next level of stairs at the stair rest platform by the powered wheels 50. And repeating the steps of going down stairs and turning at the stair rest platform until the remains are transported to the downstairs.

It should be noted that when the resistance crawler 30 is not provided, the length of the power crawler 20 may be set to be longer, the power crawler 20 extends to the front of the carrying plate 10, for example, the length is 1.6 m, and when the pickup device moves from a corridor to a staircase, one touches the front end of the power crawler 20 to the ground by adjusting the angle of the carrying plate 10 with respect to the horizontal plane, then pushes the pickup device forward, suspends the power wheel 50 on the staircase, moves the power crawler 20 to the uppermost step vertex, then pushes the pickup device forward and adjusts the angle of the carrying plate 10, makes the power crawler 20 contact at least two step vertices, and then the power crawler 20 operates to move the pickup device downward on the staircase.

After the remains are transported to the downstairs, the receiving and transporting device walks on the downstairs ground, and the specific process is the same as the walking on the corridor ground, which is not described herein again. As shown in fig. 1 and 2, the carrier means is moved to the carrier, the carrier plate 10 is tilted; as shown in fig. 5, one presses the loading plate 10 backward to be gradually leveled to make the power caterpillar 20 located on the ground, and then the power caterpillar 20 operates to make the receiving and transporting device advance, the power wheel 50 and the resistance caterpillar 30 of the receiving and transporting device partially move to the receiving and transporting plane of the receiving and transporting vehicle, the power wheel 50 is located on the receiving and transporting plane of the receiving and transporting vehicle, and then the remains can be transported to the receiving and transporting vehicle.

In another preferred embodiment, when the receiving and transporting device is butted with the receiving and transporting vehicle, the receiving and transporting device and the corpses are pulled away by the receiving and transporting vehicle together, and the corpses do not need to be transported. At this time, the power track 20 may be provided in a liftable structure, and specifically, the power track 20 is connected to the loading plate 10 through a lifting mechanism (which is the first lifting mechanism 40). When the receiving and transporting device is butted with the receiving and transporting vehicle, the power caterpillar 20 lands on the ground, the bearing plate 10 is horizontal, and the height of the bearing plate 10 can be adjusted through the first lifting mechanism 40 due to the fact that the height of the receiving and transporting plane of different receiving and transporting vehicles can be different, and the height of the power wheel 50 is matched with the upper surface of the receiving and transporting plane of the receiving and transporting vehicle. After the power crawler 20 works to enable the power wheels 50 and the resistance crawler 30 of the receiving and transporting device to partially move to the receiving and transporting plane of the receiving and transporting vehicle, the power crawler 20 stops working, the front half part of the receiving and transporting device enters the receiving and transporting vehicle and is supported by the receiving and transporting vehicle, then the power crawler 20 is lifted to be as high as the receiving and transporting plane of the receiving and transporting vehicle through the first lifting mechanism 40, then the power wheels 50 and/or the power crawler 20 are started, and the receiving and transporting device moves forwards on the receiving and transporting vehicle.

The utility model discloses a connect the fortune device when the normality, as shown in fig. 12, first elevating system 40 and second elevating system 45 fold up, reduce the volume, are convenient for accomodate, and the lower extreme of power track 20 and resistance track 30 is not less than the lower extreme of power wheel 50.

When the pick-up device is used with the power track 20 to travel on the ground, there are two ways. First, as shown in figure 5, only the power track 20 is in contact with the ground and the resistance track 30 is folded up, which requires the carrier to hold the carrier plate 10 in balance in order to keep the balance of the carrier. Second, as shown in figure 13, both the power track 20 and the resistance track 30 are in contact with the ground, and the carrier assembly is self-balancing and does not require the carrier to hold the carrier plate 10. Wherein, the resistance track 30 may be a track without a power mechanism or a track with a power mechanism, and when the resistance track 30 does not have a power mechanism, the resistance track 30 follows the power track 20 to walk on the ground; when the resistance track 30 has a powered mechanism, it operates by itself to travel on the ground in synchronization with the powered track 20.

When both the power track 20 and the resistance track 30 are grounded while the pickup unit is docked with the pickup truck, as shown in fig. 13, the first and second elevating mechanisms 40 and 45 operate to adjust the height of the carrier plate 10 such that the height of the power wheels 50 matches the upper surface of the pickup plane of the pickup truck. The power track 20 then operates to move the receiving means power wheels 50 to the receiving plane of the receiving vehicle, while the balance of the carrier plate 10 is maintained by the power wheels 50 and the power track 20. As shown in fig. 5, the second elevation structure is then operated to raise the resistance track 30 such that the lower end of the resistance track 30 is not lower than the lower end of the power wheel 50. Then the power caterpillar band 20 continues to work to enable the resistance caterpillar band 30 of the receiving device to partially move to the receiving plane of the receiving vehicle, the power caterpillar band 20 stops working, the power caterpillar band 20 is lifted to be as high as the receiving plane of the receiving vehicle through the first lifting mechanism 40, then the power wheels 50 and/or the power caterpillar band 20 are started, and the receiving device moves forwards on the receiving vehicle. It should be noted that, during the course of the transportation device walking on the corridor, going down the stairs, turning at the rest steps of the stairs, and walking on the ground below the stairs, the distance between the power track 20 and the bearing plate 10 is kept constant, for example, between 0.8 m and 1 m, and can be preset. When the receiving and transporting device is in butt joint with a receiving and transporting vehicle, the height of the bearing plate 10 is required to be adjusted through the first lifting mechanism 40 according to the height of a receiving and transporting plane of the receiving and transporting vehicle, and when the receiving and transporting device runs on the receiving and transporting plane of the receiving and transporting vehicle, the height of the power crawler 20 is required to be adjusted through the first lifting mechanism 40, so that the height of the power crawler 20 is matched with the upper surface of the receiving and transporting plane of the receiving and transporting vehicle.

In another preferred embodiment, the height of the power wheel 50 is adjustable, for example, the power wheel 50 is connected with the carrying plate 10 through a lifting mechanism (being a third lifting mechanism), the carrying plate 10 is inclined, when the receiving and transporting device walks or turns on the ground in a straight line through the power wheel 50, the power wheel 50 can be lifted, and under the condition of not lifting the power track 20, the inclination angle of the carrying plate 10 can be adjusted through lifting the power wheel 50, thereby adapting to the heights and habits of different receiving and transporting persons; and adjusting the inclination angle of the loading plate 10 by lifting the power wheels 50 is more labor-saving than lifting the power crawler 20. It should be noted that the power wheels 50 may also be connected to the resistance track 30, and the power wheels can move up and down along with the resistance track 30, and the specific connection manner is the same as the connection manner of the universal wheels 60 and the power track 20, which is not described herein again.

As shown in fig. 2, in a preferred embodiment of the present invention, the first lifting mechanism 40 and the second lifting mechanism 45 are both scissor-type lifting mechanisms, and the scissor-type lifting mechanisms are connected to a lifting driving mechanism for driving the scissor-type lifting mechanisms, such as a linear motor. The first lifting mechanism 40 and the second lifting mechanism 45 have the same structure and size, and the first lifting mechanism 40 and the second lifting mechanism 45 are symmetrically arranged in front and back. Two power caterpillar bands 20 are respectively connected with a scissor type lifting mechanism, and the two scissor type lifting mechanisms are connected through a rotating shaft.

As shown in fig. 2, the first lifting mechanism 40 includes a plurality of connecting rods 41 connected in a rotating manner, and the present invention is described by taking four connecting rods 41 as an example, the middle of the two upper connecting rods 41 is connected in a rotating manner by a pin to form a crossed structure, the middle of the two lower connecting rods 41 is connected in a rotating manner by a pin to form a crossed structure, and the lower ends of the two upper connecting rods 41 are connected in a rotating manner by a pin to the upper ends of the two lower connecting rods 41. The bearing plate 10 is fixedly connected with a hinge seat 42 and an upper sliding rail 43 extending along the length direction of the bearing plate 10, the upper front ends of the two upper connecting rods 41 are rotatably connected with the bottom of the bearing plate 10 through the hinge seat 42, and the upper rear ends of the two upper connecting rods 41 are rotatably connected with the upper sliding rail 43 through a pin shaft and can slide in the upper sliding rail 43. The frame of the power crawler 20 is also correspondingly and fixedly connected with a hinge seat 42 and a lower slide rail 44 extending along the length direction of the bearing plate 10, the lower front ends of the two lower connecting rods 41 are rotatably connected with the frame of the power crawler 20 through the hinge seat 42, and the lower rear ends of the two lower connecting rods 41 are rotatably connected with the lower slide rail 44 through a pin shaft and can slide in the lower slide rail 44.

Specifically, the linear motor can be used to drive the end of the upper rear connecting rod 41 to slide back and forth in the upper slide rail 43 and/or drive the end of the lower rear connecting rod 41 to slide back and forth in the lower slide rail 44, thereby realizing the lifting of the scissor lift mechanism. The structure and operation principle of the scissor lift mechanism are prior art and will not be described in detail here.

As shown in fig. 1, 3 and 5, in another preferred embodiment, the front end of the power crawler 20 is connected to a universal wheel 60 having an operating surface rotatable relative to the power crawler 20, the operating surface is a base plate on which the universal wheel 60 is mounted, and the universal wheel 60 and the resistance crawler 30 do not interfere with each other and are displaced from each other during movement. The front end of the frame of the power crawler 20 is rotatably connected with a connecting frame 61, the bottom plate of the universal wheel 60 is mounted on the connecting frame 61 through a bolt, the rotation axis of the connecting frame 61 is parallel to the width direction of the bearing plate 10, the connecting frame 61 is connected with a rotary driving mechanism for driving the connecting frame to rotate, and the rotary driving mechanism is a motor capable of rotating forward and backward.

As shown in fig. 3 and 5, when the power crawler 20 walks on the ground or on the stairs, the rotary driving mechanism drives the connecting frame 61 to rotate so that the acting surface of the universal wheel 60 rotates away from the ground, the universal wheel 60 does not contact with the ground or the stairs, and the universal wheel 60 is emptied. As shown in fig. 1, when the power wheel 50 travels on the ground, the rotation driving mechanism drives the connecting frame 61 to rotate so that the acting surface of the universal wheel 60 turns toward the ground, the universal wheel 60 contacts with the ground, and the universal wheel 60 can travel on the ground. When the power wheels 50 run on the ground, the universal wheels 60 also run on the ground, and the two power wheels 50 and the universal wheel 60 support the receiving and transporting device, so that the receiving and transporting device can keep balance and can automatically run without the assistance of the receiving and transporting personnel.

The universal wheels 60 may be positioned above and below the power crawler 20 by raising and lowering the universal wheels 60, for example, the universal wheels 60 may be connected to the frame of the power crawler 20 by a raising and lowering mechanism, and the universal wheels 60 may be raised or lowered by the raising and lowering mechanism. Specifically, when the power crawler 20 travels on the ground or stairs, the universal wheels 60 are raised, so that the universal wheels 60 do not contact the ground or the stairs; when the power wheel 50 travels on the ground, the universal wheel 60 descends, so that the universal wheel 60 can travel on the ground.

It should be noted that the universal wheels 60 may be connected to the carrier plate 10 instead of being installed at the front end of the power crawler 20, for example, the universal wheels 60 may be connected to the carrier plate 10 through a lifting mechanism, or the universal wheels 60 may be installed on a connecting frame 61 rotatably connected to the carrier plate 10, as long as the movement of the universal wheels 60 does not interfere with the movement of the resistance crawler 30.

In another preferred embodiment, the handling device is further provided with a controller 70, and the controller 70 is provided at the rear end of the carrier plate 10 between the two handles 12.
