The electrical system includes motor, controller, distribution cabinet, connection line, signal and lighting devices, etc.

[0003] Vertical transportation equipment is a device used for vertical transportation. When in use, vertical transportation equipment will transport the required materials to a high place. However, sometimes due to negligence of the staff, the transported materials exceed the limit of the vertical transportation equipment, and the vertical transportation equipment will tilt. If it is not discovered in time, it will collapse, causing injuries to the staff. It will also damage the building when it collapses, greatly increasing the company's construction costs. Summary of the invention

[0004] In order to solve a series of problems such as vertical transportation equipment will tilt when the existing tower crane is over-transported, and will collapse if not discovered in time, thereby causing harm to workers, the present invention provides a stable civil engineering protective enclosure that is highly practical and can be connected through simple operations.

[0005] The present invention is implemented by the following technical solutions: An over-limit alarm for vertical transportation equipment used for reinforcement and reconstruction of high-rise buildings comprises an alarm box detachably mounted on a stand of the vertical transportation equipment, wherein an annular contact piece is horizontally mounted in the alarm box through a fixing card, a hammer line suspended on the top plate of the alarm box is provided at the central axis position in the contact piece, a plumb bob is installed at the lower end of the hammer line, the lower end of the plumb bob is overlapped on the strap, a plurality of push rods are rotatably connected to the outer periphery of the strap, the middle part of each push rod passes through a support plate, the support plate is fixed to the side wall of the alarm box, a top plate is provided above the support plate through a limiting rod, the top plate is located above the push rod, a contact head located below the contact piece is fixed above the top plate, the contact piece and the contact head are electrically connected to the alarm, and the alarm is mounted above the outside of the alarm box; a ball socket is fixed at the center of the lower surface of the strap, the ball socket cooperates with a spring sleeve rod with a ball head at the top, the spring sleeve rod is installed on the bottom plate of the alarm box and is located on the center line of the strap.

[0006] During implementation, it includes an alarm box that can be detachably installed on the vertical frame of the vertical transportation equipment. The alarm box is arranged in a cubic shape as a whole. A box door is arranged on the front of the alarm box, and a fixing seat is welded on the back of the alarm box. The fixing seat is arranged in a T shape as a whole, and the fixing seat is detachably connected to the vertical frame.

[0007] An annular contact piece is horizontally installed in the alarm box through a fixing card. The fixing card is arranged in a U shape as a whole. The contact piece is installed in a slot of the fixing card. The fixing card is detachably installed on the inner wall of the alarm box.

[0008] A hammer line suspended on the top plate of the alarm box is provided at the central axis position of the contact piece, that is, the hammer line passes through the ring of the contact piece, and a plumb bob is installed at the lower end of the hammer line, and the lower end of the plumb bob is overlapped on the strapping board. When the strapping board is horizontal, the lower end of the plumb bob is located in the center of the strapping board. When the strapping board is tilted, the position of the plumb bob on the strapping board shifts at the same time. Under the rebound action of the spring sleeve rod, the plumb bob will not leave the strapping board but move to the edge of the strapping board. Under the pressure of the plumb bob, the strapping board tilts.

[0009] The overall shape of the strap is a disc. When balanced, the arc-shaped tip of the plumb bob is located in the center of the strap. The outer periphery of the strap is rotatably connected to a number of push rods. Specifically, side grooves are evenly provided on the edge of the strap. The side grooves are radially opened around the circumference of the strap. Push rods are rotatably installed in the side grooves through plug shafts. Specifically, the plug shaft is disassembled and installed at the notch in the side groove. A swivel card that can rotate freely along the plug shaft is provided on the outer sleeve of the plug shaft. The length of the swivel card is less than the length of the side groove on the strap. The swivel card is fixed to the bottom end of the push rod. The up and down movement of the push rod is achieved by rotating the swivel card relative to the plug shaft.

[0010] The push rod is arranged in an S shape as a whole. The middle part of each push rod passes through the support plate, and the support plate is fixed on the side wall of the alarm box. Specifically, a mounting hole is opened on the support plate at a position opposite to the side groove. The push rod passes through the mounting hole and leaves a gap with the mounting hole, that is, the inner diameter of the mounting hole is larger than the outer diameter of the push rod. The gap is used to allow for the push rod to tilt at a small angle to avoid interference. The push rod moves up and down in the mounting hole.

[0011] A top plate is provided above the support plate through a limit rod, that is, a limit rod is evenly fixed above the support plate. In this embodiment, the limit rod is evenly provided with a, the top end of the limit rod passes through a sliding slot opened on the top plate, and a gap is left between the limit rod and the sliding slot, that is, the inner diameter of the sliding slot is larger than the outer diameter of the limit rod, and the gap is used for a margin for the top plate to tilt at a small angle to avoid interference between the top plate and the limit rod; the top plate is located above the push rod, the top plate is in the shape of an annular plate, the hammer line passes through the annular center of the top plate, the outer edge of the top plate is supported on the top end of the push rod, and the top plate is tilted at a small angle by the push rod; a contact is fixed above the top plate and is located below the contact piece, and a gap is left between the contact and the contact piece. When the top plate is tilted, the contact contacts the contact piece, and the contact is in the shape of an annular plate and is coaxially arranged with the contact piece. Specifically, a contact is fixed on the inner edge of the top plate through a pair of vertical rods, and the contact moves synchronously with the top plate, the contact piece and the contact are electrically connected to the alarm, and the contact between the contact piece and the contact triggers the alarm to alarm, and the alarm is installed above the outside of the alarm box.

[0012] A ball socket is fixed in the center of the lower surface of the strap, and the ball socket cooperates with a spring sleeve rod with a ball head on the top. The hammer line and the plumb bob droop naturally, and the spring sleeve rod is in a contracted state under the action of the plumb bob. The spring sleeve rod is installed on the bottom plate of the alarm box and is located on the center line of the strap. Specifically, the spring sleeve rod includes a guide rod vertically installed on the bottom plate inside the alarm box, the guide rod is slidably connected to the outer sleeve rod, and a spring is connected to the outer sleeve of the guide rod. The lower end of the spring is installed on the bottom plate of the alarm box, and the upper end of the spring is installed on the end face of the outer sleeve rod. A ball head cooperating with the ball socket is fixed on the top of the outer sleeve rod, that is, the guide rod and the hammer line are coaxially arranged, and the guide rod and the hammer line correspond to each other.

[0013] When in use, the alarm box is installed on the stand of the vertical transportation equipment. The alarm box is installed through a fixed seat. The installation position of the alarm box is flexible. After installation, the device remains horizontal, the ring centers of the contact pieces, contacts, top plates, support plates and the center of the circle of the strap are all on the plumb line, the lower part of the plumb bob is located at the center of the circle of the strap and presses down on the strap. After the strap is pressed down by the plumb bob, the strap remains horizontal, the spring in the spring sleeve rod contracts, and the strap will not push up the plumb bob. When the hammer head of the plumb bob is placed in the center of the strap, the center of the strap can be compressed, the strap will not deviate, the push rod is evenly pressed against the edge of the top plate, the contacts on the top plate are kept away from the contact pieces, the alarm is in a closed state, and the alarm is not activated when the vertical transportation equipment vertically transports materials.

[0014] If the overrun causes the vertical transport equipment to deform and tilt, the stand tilts, and the alarm box tilts, the plumb line will remain vertically downward due to gravity and will not swing significantly, driving the plumb bob to move to the edge of the slat. Under the pressure of the plumb bob, the slat tilts. Due to the upward elastic force of the spring, the plumb bob will not separate from the slat, and the ball socket will rotate relative to the ball head to achieve the tilt of the slat. The plumb bob presses down on the side of the slat, causing the slat as a whole to tilt, causing the corresponding side of the slat to tilt upward, thereby causing the corresponding push rod to push up, and then push the top plate up, The plate can drive the contact to move up, thereby achieving contact with the contact piece and the alarm is activated. Specifically, the overall board is inclined, and the slewing card rotates relative to the plug-in shaft to lift the push rod upward. The middle part of the push rod moves upward relative to the support plate, and the top of the push rod lifts the top plate on this side upward. The top plate slides relative to the limit rod. The top plate is tilted and drives the contacts to rotate synchronously through the vertical rod. The contacts are tilted and contact the contact piece, and the alarm is activated. This realizes the alarm for deformation of the vertical transportation equipment caused by over-limit transportation of the equipment, thereby realizing timely maintenance of the vertical transportation equipment.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an over-limit alarm for vertical transportation equipment for reinforcement and reconstruction of high-rise buildings. The alarm box is directly installed on the stand of the vertical transportation equipment. The installation position of the alarm box can be flexibly changed. The alarm is not activated when the vertical transportation equipment is vertically transporting materials. After over-limit transportation, the vertical transportation equipment will deform and tilt due to the weight of the materials, and the hammer line will contact the touch to make the alarm sound. The strap will drive the contact to contact the contact piece for secondary contact, thereby preventing the situation where the hammer line is not sufficient to contact the contact piece after the equipment is deformed. The alarm is activated by the secondary contact to realize the alarm of the deformation of the vertical transportation equipment caused by the over-limit transportation of the equipment, thereby realizing timely maintenance of the vertical transportation equipment.

[0016] The present invention can monitor the operating status of the vertical transportation equipment in real time. Once the safety limit of the equipment is exceeded, the alarm will immediately send out an alarm signal to avoid serious accidents such as overturning of the vertical transportation equipment due to overloading. It is helpful to keep the equipment running within a safe working range. It can reduce unstable factors such as shaking and imbalance caused by over-limit operation of the equipment. It can also reduce the damage to the equipment caused by over-limit operation. BRIEF DESCRIPTION OF THE DRAWINGS

The lower end of the plumb bob 7 is overlapped on the strap 20. When the strap 20 is horizontal, the lower end of the plumb bob 7 is located in the center of the strap. When the strap is tilted, the position of the plumb bob on the strap is shifted at the same time. Under the rebound action of the spring sleeve rod, the plumb bob will not leave the strap 20 but move to the edge of the strap 20. Under the pressure of the plumb bob, the strap is tilted.

[0029] The strap 20 is in the shape of a disc as a whole. When balanced, the arc-shaped tip of the plumb bob 7 is located at the center of the strap 20. The outer periphery of the strap 20 is rotatably connected to a plurality of push rods 14. Specifically, side grooves 19 are evenly provided on the edge of the strap 20.

[0031] like Figure 7 As shown: a top plate 21 is provided above the support plate 10 through a limiting rod 23, that is, the limiting rod 23 is evenly fixed above the support plate 10, the top end of the limiting rod 23 passes through a sliding opening 24 opened on the top plate 21, and a gap is left between the limiting rod 23 and the sliding opening 24, that is, the inner diameter of the sliding opening 24 is larger than the outer diameter of the limiting rod 23, and the gap is used for the margin of the top plate to tilt at a small angle to avoid interference between the top plate and the limiting rod; the top plate 21 is located above the push rod 14, the top plate 21 is in the shape of a ring sheet, the hammer line 9 passes through the center of the top plate 21, and the outer edge of the top plate 21 is supported on the top end of the push rod 14, through the push rod 14 The rod 14 is pushed up to make the top plate 21 tilt at a small angle; a contact 22 is fixed above the top plate 21 and is located below the contact piece 8. A gap is left between the contact 22 and the contact piece 8. When the top plate 21 is tilted, the contact 22 contacts the contact piece 8. The contact 22 is in the shape of a ring and is arranged coaxially with the contact piece 8. Specifically, the inner edge of the top plate 21 is fixed with the contact 2 by a pair of vertical rods 25. The contact 22 moves synchronously with the top plate 21. The contact piece 8 and the contact 22 are electrically connected to the alarm 2. The contact between the contact piece 8 and the contact 22 triggers the alarm 2 to alarm. The alarm 2 is installed above the outside of the alarm box 3.

[0032] like Figure 6As shown: a ball socket 18 is fixed in the center of the lower surface of the strap 20, and the ball socket 18 cooperates with a spring sleeve rod with a ball head 17 on the top. The plumb line and the plumb bob naturally droop, and the spring sleeve rod is in a contracted state under the action of the plumb bob. The spring sleeve rod is installed on the bottom plate of the alarm box 3 and is located on the center line of the strap 20. Specifically, the spring sleeve rod includes a guide rod 13 vertically installed on the bottom plate inside the alarm box 3, and the guide rod 13 is slidably connected to the outer sleeve rod 11. The guide rod 13 is connected to the outer sleeve of the guide rod 13. The lower end of the spring 12 is installed on the bottom plate of the alarm box 3, and the upper end of the spring 12 is installed on the end face of the outer sleeve rod 11. The top of the outer sleeve rod 11 is fixed with a ball head 17 that cooperates with the ball socket 18, that is, the guide rod 13 and the plumb line 9 are coaxially arranged, and the guide rod 13 and the plumb line 9 correspond to each other.

[0033] When in use, the alarm box 3 is installed on the stand 1 of the vertical transportation equipment. The alarm box 3 is installed through the fixing seat 5.

[0034] If the vertical transport equipment is deformed and tilted due to over-limit, the stand 1 tilts, the alarm box 3 tilts, and the plumb line 9 remains vertically downward due to the gravity and will not swing significantly, driving the plumb bob 7 to move toward the edge of the butt plate 20. Under the pressure of the plumb bob 7, the butt plate 20 tilts. Due to the upward elastic force of the spring 12, the plumb bob 7 will not separate from the butt plate 20, and the ball socket 18 rotates relative to the ball head 17 to achieve the tilt of the butt plate 20. The plumb bob 7 presses down on the side of the butt plate 20, so that the butt plate 20 is tilted as a whole, causing the corresponding side of the butt plate 20 to tilt upward, thereby causing the corresponding push rod 14 to push up, and then push the top plate 21 upward, and the top plate 21 can drive the contact 22 to move upward, thereby achieving contact with the contact piece 8, and the alarm 2 is activated. Specifically, the board 20 is tilted as a whole, and the slewing card 15 rotates relative to the plug-in shaft 16 to push the push rod 14 upward. The middle part of the push rod 14 moves upward relative to the support plate 10, and the top of the push rod 14 pushes the top plate 21 on this side upward. The top plate 21 slides relative to the limit rod 23. The top plate is tilted to drive the contact 22 to rotate synchronously through the vertical rod 25. The contact 22 is tilted to contact the contact piece 8, and the alarm 2 is activated. An alarm is realized for the deformation of the vertical transportation equipment caused by the over-limit transportation of the equipment, thereby realizing timely maintenance of the vertical transportation equipment.
