Description

[0002] During the exhibition hall layout process, in order to create a good exhibition atmosphere, the exhibition hall needs to install various display props, such as display racks, display boards, light boxes, poster boards, projection screens, monitoring, etc. The hoisting device can accurately hoist the exhibits to the designated display location according to the characteristics of the exhibits and the requirements of the exhibition layout, so as to achieve the best display effect.

[0003] Existing lifting equipment is generally placed directly on the ground, and heavy objects are piled on the top of the base of the equipment to prevent it from tipping over during the lifting process. However, exhibition halls are different from common construction scenes outside. The props required for lifting and layout in exhibition halls are complex and diverse, and their positions are relatively unstable. Therefore, lifting equipment fixed to the ground and piled with heavy objects is not easy to move and cannot meet the needs of exhibition halls. In addition, some common movable lifting equipment is difficult to control the stability of the base and is prone to tipping over. There is usually only one hook for lifting work. When special materials need to be lifted, such as glass panels, billboards, wooden boards and other materials, these sheet materials are not easy to fix and are very easy to fall off and cause damage.

[0068] See also Figure 1-8 The present invention is a hoisting device for exhibition hall construction, comprising a base 1, a rotating seat 4, a top plate 9, an anti-dumping component and a hoisting component.

[0069] A driving wheel 3 is provided at the bottom of the base 1;

[0070] The rotating seat 4 is installed on the base 1 through a rotating assembly;

[0071] The top plate 9 is mounted on the rotating seat 4 through a lifting assembly;

[0072] The anti-dumping assembly is connected to the side wall of the base 1;

[0073] The hoisting assembly is arranged on the top plate 9; the hoisting assembly includes two sets of winding frames, a hook 24 and a plate clamping assembly. The two sets of winding frames are symmetrically installed on the top plate 9; a pull rope 18 is wound on the winding frame, and a fixing block 21 is arranged at the tail end of the pull rope 18; the hook 24 is connected to one of the fixing blocks 21; and the plate clamping assembly is connected to the other fixing block 21.

[0074] When the hoisting equipment of the present invention is used, the construction materials are first classified and placed on the hook 24 and the plate clamping assembly; the pull rope 18 is rolled up by the winding frame, so as to lift the hook 24, the plate clamping assembly and the construction materials; the height of the top plate 9 is adjusted by the lifting assembly, so that the height position of the construction materials can be further adjusted; the angle of the rotating seat 4 is adjusted by the rotating assembly, so that the horizontal position of the construction materials can be further adjusted; after the construction materials are hoisted to the work station, the hook 24 and the plate clamping assembly are reset by the winding frame, the lifting assembly and the rotating assembly, and a new round of hoisting work is carried out. The present invention improves the flexibility, applicability and practicality of the hoisting equipment by arranging the rotating assembly, the lifting assembly, the anti-dumping assembly and the hoisting assembly.

[0075] It should be noted that:

[0076] 1) The driving wheel 3 should be an integrated mobile wheel with walking ability, driving force and steering ability, and can realize the functions of self-walking and self-steering. It is a common driving wheel 3 on the market and will not be described here.

[0077] 2) The anti-dumping assembly is used to improve the stability of the base 1 and prevent the hoisting assembly from tipping over when hoisting goods.

[0078] 3) The hoisting assembly uses two sets of winding frames, which are respectively connected to the hook 24 and the plate clamping assembly. The hook 24 can hoist most construction materials, and the plate clamping assembly can hoist some special materials, such as glass plates, billboards, wooden boards, etc. These plate materials are not easy to fix, so it is not convenient to use the hook 24 to directly hoist.

[0079] Specifically, the plate clamping assembly of the present invention is mainly used for hoisting plates, so it is sufficient to fix the plates, such as a common clamping structure composed of a U-shaped plate and bolts. However, considering stability and convenience, in some embodiments of the present invention, please combine Figure 1-6 The plate clamping assembly includes a hanging plate 29, two clamping plates 25, a cross bar 30 and a driving member.

[0080] The hanging plate 29 is connected to the fixing block 21 through the connecting belt 19; a movable groove 2901 is provided on the hanging plate 29;

[0081] Two clamping plates 25 are symmetrically arranged in the movable groove 2901; a clamping groove is recessed in the side wall of the bottom of the clamping plate 25; an air channel 2501 is arranged in the wall of the clamping groove; two ends of the air channel 2501 are respectively located at the top and side wall of the clamping groove, and piston plates 32 are arranged in both ends of the air channel 2501; the two piston plates 32 are respectively connected to a squeeze plate 34 and a pressure plate 33 through a connecting rod; a return spring 31 is arranged between the squeeze plate 34 and / or the pressure plate 33 and the inner wall of the air channel 2501;

[0082] The cross bar 30 is fixedly installed in the movable groove 2901 and slidably penetrates the two clamping plates 25;

[0083] The driving member is used to drive the two clamping plates 25 to move toward or away from each other along the cross bar 30 .

[0084] When the sheet clamping assembly is in use, the two sides of the sheet are placed in the two clamping grooves, and the driving member is used to drive the two clamping plates 25 to move toward each other, so that the squeezing plates 34 on both sides contact the two ends of the sheet and squeeze the pressure plate 33 at the other end of the air channel 2501 downward, thereby squeezing the top of the sheet, achieving the double clamping and fixing of the sheet in the horizontal and vertical directions, and improving the stability of the sheet. When the designated work position is reached, the driving member is used to make the two clamping plates 25 move away from each other, and the squeezing plate 34 releases the horizontal clamping. Under the action of the reset spring 31, the pressure plate 33 automatically resets and releases the vertical clamping, so that the sheet can be easily and quickly separated, which is convenient, fast and highly practical.

[0085] Additional explanations are needed:

[0086] 4) First, the movable groove 2901 of the present invention can be a complete long groove, or it can be two short grooves that are symmetrical and spaced apart on the hanging plate 29. Secondly, the bottom of the squeezing plate 34 of the present invention can be in sliding contact with the bottom surface of the clamping groove to improve the clamping effect and avoid the plate from being stuck in the gap. Furthermore, the clamping surfaces of the squeezing plate 34 and the pressure plate 33 should be provided with protective pads to avoid damage to the surface of the plate to be hoisted. Finally, the specific type of the driving part is not limited as long as it can achieve the driving effect, such as the common two groups of symmetrically arranged hydraulic cylinders, or a bidirectional lead screw, which are respectively matched with the two clamps 25, and one end is connected to the corresponding drive motor.

[0087] Specifically, the reel frame used in the present invention may be a common reel structure, such as some common structures for reeling in cables or reeling in ropes. Figure 1 and Figure 7 , the structure of the winding frame is illustrated by way of example. The winding frame includes two side plates 10 , a winding rod 12 , a reciprocating screw rod 14 , a slider 15 and a guide rod 13 .

[0088] Two side panels 10 are symmetrically mounted on the top panel 9;

[0089] The reeling rod 12 is rotatably mounted between the two side plates 10, and one end of the reeling rod 12 is connected to a reeling motor 11; the pull rope 18 is reeled on the reeling rod 12;

[0090] The reciprocating screw rod 14 is rotatably mounted between the two side plates 10 and is transmission-connected to the winding rod 12;

[0091] The slider 15 is sleeved outside the reciprocating screw rod 14 and cooperates with the reciprocating screw rod 14; a wire ring 16 is installed on the top of the slider 15;

[0092] The guide rod 13 is fixedly installed between the two side plates 10 and slidably penetrates the slider 15 .

[0093] One end of the pull rope 18 is wound on the winding rod 12, and the other end passes through the wire ring 16 and is connected to the fixed block 21. When winding, the winding motor 11 drives the winding rod 12 and the reciprocating screw rod 14 to work at the same time. The winding rod 12 winds the pull rope 18, and the reciprocating screw rod 14 drives the sliding and wire ring 16 to move back and forth, so that the pull rope 18 is evenly wound on the winding rod 12.

[0094] Furthermore, in consideration of the stability of the pull rope 18 and avoiding interference of the construction materials to be hoisted with the device body, in some embodiments, rotating rods 23 are symmetrically arranged on both sides of the lifting plate 8; one end of the rotating rod 23 is rotatably installed on the lifting plate 8, and a limiting rod 17 is arranged at the other end; a connecting rod 20 is arranged between the rotating rod 23 and the side wall of the top plate 9.

[0095] Of course, in order to fully adjust the position of the fixed block 21 and facilitate the hoisted construction materials to reach the designated position better, the length of the connecting rod 20 is adjustable. By adjusting the length of the connecting rod 20, the angle between the rotating rod 23 and the lifting plate 8 can be achieved, thereby achieving the position adjustment of the fixed block 21. Specifically, the type of the connecting rod 20 can be a hydraulic push-pull rod; it can also be a split sleeve sleeve rod, and the sleeve sleeve rod is fixed by a connecting pin; of course, it can also be other implementation forms, as long as the length can be changed.

[0096] It is necessary to add that:

[0097] 5) An annular groove can be set in the middle of the limiting rod 17, and the pull rope 18 is slidably set in the groove. The pull rope 18 is limited by the groove to avoid the pull rope 18 from escaping from the groove as much as possible. The swing of the pull rope 18 when winding can be reduced, and the stability of the fixed block 21 and the lifting material when rising can be improved.

[0098] Specifically, the rotating assembly used in the present invention may be a common rotating structure. Figure 7 The rotating assembly may include a rotating shaft 27, a rotating motor (not shown in the figure) and a plurality of supporting rods.

[0099] One end of the rotating shaft 27 is rotatably mounted on the base 1, and the other end is fixedly connected to the rotating base 4; a driven gear 26 is fixedly mounted on the rotating shaft 27;

[0100] The rotating motor is mounted on the base 1, and a driving gear 28 is fixedly mounted on the output shaft; the driving gear 28 and the driven gear 26 are meshed with each other;

[0101] A plurality of support rods are evenly distributed around the periphery of the rotating shaft 27 ; one end of the support rod is mounted on the bottom of the rotating seat 4 , and the other end is slidably disposed on the base 1 .

[0102] The driving gear 28 is driven to rotate by the rotating motor, and the driven gear 26 cooperates with the driving gear 28 to rotate the rotating shaft 27, thereby driving the rotating seat 4 to rotate. It should be noted that in order to improve stability, an annular groove 101 can be preset on the surface of the base 1 so that the bottom of the support rod can be slidably arranged in the annular groove 101.

[0103] Specifically, the lifting assembly used in the present invention may be a common lifting structure. Figure 1-3 The lifting structure includes a lifting motor 5, a lifting screw rod 7, a plurality of auxiliary rods 6, a lifting plate 8 and a plurality of fixing rods 22.

[0104] The lifting motor 5 is installed on the rotating seat 4;

[0105] The lifting screw rod 7 is fixedly connected to the output shaft of the lifting motor 5;

[0106] A plurality of auxiliary rods 6 are arranged on the periphery of the lifting screw rod 7; one end of the auxiliary rod 6 is vertically mounted on the rotating seat 4;

[0107] The lifting plate 8 is slidably sleeved on the auxiliary rod 6 and cooperates with the lifting screw rod 7;

[0108] A plurality of fixing rods 22 are fixedly installed between the top plate 9 and the lifting plate 8 .

[0109] When the lifting motor 5 is working, it drives the lifting screw 7 to rotate, so that the lifting plate 8 moves up and down along the auxiliary rod 6, and then the top plate 9 is driven by the lifting plate 8 to move up and down.

[0110] The anti-dumping assembly in the present invention is to improve the stability of the base 1 and prevent the lifting assembly from tipping over when lifting goods. A common method is to add counterweights on both sides of the base 1. Although the counterweights can improve stability, they increase the overall weight of the device. In one embodiment of the present invention, the anti-dumping assembly may include two sets of extension seats 2 located on both sides of the base 1; universal wheels are provided at the bottom of the extension seat 2, and a distance adjustment assembly is provided between the extension seat 2 and the base 1; the distance adjustment assembly is used to adjust the distance L between the extension seat 2 and the base 1. The specific type of the distance adjustment assembly is not limited, and it can change the distance, such as a common cylinder, a hydraulic push rod, or a motor-driven push-pull structure, etc., which will not be described in detail here. By adjusting the position of the extension seat 2, the base 1 can be auxiliary supported, which greatly reduces the probability of tipping over, and the extension seat 2 can be retracted against the side wall of the base 1 during normal use, and the volume of the base 1 will not be increased on a large scale.

[0111] In order to improve practicality, in some embodiments of the present invention, a weight sensor, a height sensor, a distance sensor, a laser sensor, an alarm and a controller are also provided.

[0112] The weight sensor is arranged on the fixed block 21 and is used to detect the weight M of the goods carried by the fixed block 21;

[0113] The height sensor is arranged on the fixing block 21 and is used to detect the height H between the fixing block 21 and the top plate 9;

[0114] The distance sensor is arranged on the fixing block 21 and is used to detect the horizontal distance L1 between the fixing block 21 and the top plate 9;

[0115] The laser sensor is arranged on the base 1 and is used to detect the width L2 between obstacles on both sides of the travel channel in real time;

[0116] The siren is used in case of an alarm;

[0117] The controller is electrically connected to the driving wheel 3, the rotating assembly, the weight sensor, the height sensor, the distance sensor, the distance adjustment assembly, the laser sensor and the alarm; the controller is used to:

[0118] Ⅰ. Determine in real time whether the distance L is less than a preset threshold value. If so, control the distance adjustment component to increase the distance L between the base 1 and the extension base 2 until it is greater than the preset threshold value;

[0119] Ⅱ. When the distance adjustment component increases the distance L between the base 1 and the extension base 2 to a limit value, and it is still less than a preset threshold, the control alarm will sound an alarm;

[0120] III. When an obstacle is detected in the direction of travel in real time, and the total length between the two extension seats 2 is greater than the width L2, the distance adjustment component is controlled to reduce the distance L between the base 1 and the extension seat 2, until the total length between the two extension seats 2 is less than the width L2, provided that the distance is greater than the preset threshold. If the total length between the two extension seats 2 cannot be less than the width L2, provided that the distance is greater than the preset threshold, it is determined whether the width of the base 1 is greater than the width L2. If so, the alarm is controlled to sound an alarm. Otherwise, the driving wheel 3 is controlled to drive the base 1 and the extension seat 2 to rotate, and the vehicle travels over the current obstacle road condition with the extension seat 2 as the forward end.

[0121] IV. When judging in real time whether it is less than a preset threshold, if so, the rotating component is controlled to stop working.

[0122] By setting up weight sensors, height sensors, distance sensors, laser sensors, alarms and controllers, the status of the lifting equipment can be detected in real time, and the overall stability of the lifting equipment can be evaluated in real time, thereby improving the stability and safety during lifting.

[0123] Furthermore, in one embodiment, a method for using the above-mentioned lifting equipment is also disclosed, comprising the following steps:

[0124] Place the construction materials in categories on the hooks 24 and the plate clamping assembly;

[0125] The draw rope 18 is reeled in by a reeling frame, thereby lifting the hook 24 and the plate clamping assembly and the construction materials;

[0126] The height of the top plate 9 is adjusted by using the lifting assembly, so that the height position of the construction materials can be further adjusted;
