Although the force is evenly applied to both sides of the cage during operation, excessive wear of the pulley and the lifting drive mechanism is avoided, and the operating stability of the lifting device is improved, when the lifting device is running, the weight of the cage is entirely borne by the lifting drive mechanism, so that it is always in a load operation state, consuming too much electric energy and affecting the life of the equipment.

[0015] Compared with the prior art, the present invention provides a lifting device for electromechanical engineering construction, which has the following beneficial effects: The lifting device for electromechanical engineering construction can release and retract the gravitational potential energy of the lifting mechanism when the lifting mechanism is raised or lowered by setting a counterweight block, thereby reducing the load of the lifting mechanism.

[0017] The lifting device for electromechanical engineering construction can conveniently install the support block and the transmission chain together by setting a clamping plate, so as to facilitate the use of the transmission chain to transmit power. Moreover, when the hoisting mechanism stalls and falls, the impact force on the support block can be used to separate the support block from the clamping plate, so that the brake plate on the support block can be used to brake inside the brake groove to prevent the hoisting mechanism from stalling and falling.

[0018] The lifting device for electromechanical engineering construction can cooperate with the rotation of the rotating rod by setting an electromagnet, and use the lifting and lowering of the lifting mechanism to control the movement of the sliding column.

Under the action of the tensioning member, when the sliding column moves outward, the brake shaft can be prevented from rotating. At the same time, after the sliding column moves outward, the end of the sliding column is located under the support block, which can block the descent of the support block, prevent the brake plate from failing to stop the lifting mechanism, and further prevent the lifting mechanism from stalling and falling.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] For an embodiment of the present invention, please refer to Figures 1 to 15 , including a lifting frame 1 and a hanging box 501, the hanging box 501 is slidably arranged between two symmetrical lifting frames 1 through a limiting pulley 505, the upper and lower lifting frames 1 are connected by a reinforcing plate 2 and a wall-mounted frame 3, the wall-facing side of the lifting frame 1 is installed on the outside of the wall through the wall-mounted frame 3, a lifting mechanism 4 is arranged on the top of the hanging box 501, and trapezoidal card plates 503 are arranged on the left and right sides of the hanging box 501, and a notch is arranged on the side of the lifting frame 1 close to the hanging box 501 to facilitate the trapezoidal card plate 503 to slide up and down; An energy storage mechanism is arranged inside the lifting frame 1, and the energy storage mechanism includes two symmetrically arranged transmission chains 106, two sprockets 105 are meshed at the bottom of the two transmission chains 106, and the two sprockets 105 are connected by a brake shaft 118. The transmission path of the transmission chain 106 is limited by a chain shell 107 and a chain groove 102 arranged inside the lifting frame 1. One end of the transmission chain 106 supports the counterweight block 103 through the lifting plate 104, and the other end of the transmission chain 106 is clamped with a support block 7 supporting the trapezoidal clamping plate 503 through a clamping plate 8. A drum brake mechanism is arranged outside the brake shaft 118, and a pendulum mechanism for controlling the drum brake mechanism is arranged inside a side wall of the lifting frame 1 close to the wall.

[0023] During specific use, the lifting frame 1 is connected into one piece up and down by the reinforcement plate 2 and the wall-mounted frame 3, and then the lifting frame 1 is connected to the outer wall of the building by using the wall-mounted frame 3. After the lifting frame 1 is installed, the limiting pulley 505 is used to install the hanging box 501 between the lifting frames 1. When transporting electromechanical equipment, the electromechanical equipment is placed inside the hanging box 501, and the hanging box 501 is lifted and lowered by the lifting mechanism 4. When the hanging box 501 descends, the gravitational potential energy of the hanging box 501 is collected by the energy storage mechanism. At the same time, after the gravitational potential energy is stored, the pendulum mechanism is used to control the drum brake mechanism to brake the energy storage mechanism. When the hanging box 501 rises, the drum brake mechanism is controlled to be released by the pendulum mechanism, and the rise of the hanging box 501 is assisted by the descent of the counterweight block 103, thereby reducing the load of the lifting mechanism 4.

[0024] like Fig.11 and Fig.12 As shown, the side of the lifting plate 104 is provided with a side pulley 115 through a bearing, and the side pulley 115 rolls on the inner wall of the chain groove 102. The interior of the lifting frame 1 is provided with a load-bearing hook 116 that cooperates with the lifting plate 104 to prevent the lifting plate 104 from falling excessively.

[0025] During specific use, when the lifting plate 104 is raised or lowered, the side pulley 115 is used to slide with the inner wall of the chain groove 102 to reduce the friction between the lifting plate 104 and the inner wall of the chain groove 102 when the lifting plate 104 is raised or lowered. When the lifting plate 104 is lowered to the lowest position, the load-bearing hook 116 is used to drag the bottom of the lifting plate 104 to prevent the lifting plate 104 from falling excessively.

[0026] like Figure 12-14As shown, the drum brake mechanism includes a hinged plate 117 arranged on the inner wall of the lifting frame 1, one end of the hinged plate 117 is hinged with two clamping plates 119, the inner wall of the clamping plate 119 is provided with two arc-shaped brake pads 120, the ends of the two clamping plates 119 away from the hinged plate 117 are connected by a tensioning member 121, and the middle parts of the ends of the two clamping plates 119 away from the hinged plate 117 are provided with symmetrical semi-cylinders 122, the inner wall of the lifting frame 1 is provided with a magnet plate 108, the middle part of the magnet plate 108 is slidably provided with a sliding column 114, one end of the sliding column 114 is provided with a wedge-shaped end inserted between the semi-cylinders 122, the middle part of the magnet plate 108 is symmetrically provided with two electromagnets 112 about the sliding column 114, and the front and rear sides of both ends of the sliding column 114 are respectively provided with an internal magnet 100 and an external magnet 113 cooperating with the electromagnet 112.

[0027] During specific use, under the control of the pendulum mechanism, after the lifting plate 104 rises to the highest point, the electromagnet 112 is instantly energized, and the magnetism between the magnetic poles is used to attract the internal magnet 100, while repelling the external magnet 113, so that the wedge-shaped end of the sliding column 114 is pulled out from between the two semi-cylinders 122, and the tensioning piece 121 is used to tighten the clamping plate 119, and the brake pad 120 is pressed tightly against the surface of the brake shaft 118, thereby preventing the brake shaft 118 from rotating, thereby achieving the purpose of storing gravitational potential energy. When the hanging box 501 rises, the pendulum mechanism is controlled to control the electromagnet 112 to be instantly energized in the reverse direction, so that the wedge-shaped end of the sliding column 114 is inserted between the two semi-cylinders 122, so that the tensioning piece 121 is elongated, and the brake shaft 118 is separated from the brake pad 120, and the counterweight block 103 will fall naturally, and the transmission of the transmission chain 106 will assist the lifting of the hanging box 501.

[0028] like Fig.14 and Fig.15 As shown, the pendulum mechanism includes a rotating chamber 602 opened inside the rear side wall of the lifting frame 1, the interior of the rotating chamber 602 is movably connected with a rotating rod 601 through a bearing shaft 604, a striking hammer 603 is provided at the longer end of the rotating rod 601, the top and bottom of the rotating chamber 602 are respectively slidably connected with an upper counterweight plate 612 and a lower counterweight plate 609, the bottom of the upper counterweight plate 612 is provided with an upper power-connecting plate 611, and the top of the lower counterweight plate 609 is provided with a lower power-connecting plate 608.

[0029] The top wall of the rotating chamber 602 is provided with a protective ring 613, and a power switch 614 is provided inside the protective ring 613. The bottom wall of the rotating chamber 602 is fixedly connected with a rebound airbag 610, and the top of the rebound airbag 610 is fixedly connected to the lower counterweight plate 609. A push rod groove 605 is opened on the middle bottom surface of the rotating chamber 602, and the bottom wall of the push rod groove 605 is fixedly connected with an ejection rod 607 through an ejection elastic member 606. The top of the ejection rod 607 supports the middle part of the longer end of the rotating rod 601, and the left and right side walls of the locking groove 510 are provided with a clamping block 507 used in conjunction with the exposed end of the rotating rod 601.

[0030] When in use, when the hanging box 501 rises, the end of the rotating rod 601 is lifted upward by the clamping block 507, so that the rotating rod 601 presses down the ejector rod 607, and at the same time, the ejector rod 607 enters the ejector rod groove 605. After the clamping block 507 lifts the end of the rotating rod 601 to the highest position, the knocking hammer 603 contacts the lower power plate 608 and is energized. At the same time, under the action of inertia, the lower power plate 608 presses down the rebound airbag 610, so that when the side wall of the clamping block 507 slides along the rotating rod 601, the knocking hammer 603 and the lower power plate 608 are always connected, thereby controlling the drum brake mechanism and energizing the electromagnet 112. When the hanging box 501 descends, the end of the rotating rod 601 is pressed down by the clamping block 507 when it descends to make the rotating rod 601 rotate. When the pressing block 507 falls, the striking hammer 603 is in contact with the upper power-connecting plate 611 and energized. At the same time, the striking hammer 603 uses inertia to strike the upper counterweight plate 612 upward. The upper counterweight plate 612 will slide upward to a certain height, and then fall down when the rotating rod 601 has not yet lost contact with the side wall of the clamping block 507, so that the striking hammer 603 and the upper power-connecting plate 611 are continuously in contact and energized. At this time, the electromagnet 112 is energized in the reverse direction. When the clamping block 507 falls at an overspeed or falls, the clamping block 507 raises the striking hammer 603 at a faster speed, so that the striking hammer 603 strikes the upper power-connecting plate 611 violently, which will move the upper counterweight plate 612 upward to turn on the power switch 614. The power switch 614 is connected to the electromagnet 112 inside the lifting frame 1 at the adjacent position below, so that the electromagnet 112 is energized to pull out the sliding column 114, thereby braking the drum brake mechanism below.

[0031] like Figure 5-Figure 10 As shown, a movable cavity 701 is provided inside the support block 7, and a clamping plate 702 is connected to the movable cavity 701 through a brake elastic member 705. A mounting groove 801 is provided inside the clamping plate 8 to cooperate with one end of the clamping plate 702 extending out of the movable cavity 701. A brake column 706 is provided at the other end of the clamping plate 702, and a brake component 704 is provided at one end of the brake column 706 extending out of the movable cavity 701. A brake groove 111 cooperating with the brake component 704 is provided on the side wall of the lifting frame 1.

[0032] The front and rear sides of the support block 7 are both provided with sliding blocks 703, the inner wall of the snap-in plate 8 is provided with a T-shaped groove 804 used in conjunction with the sliding block 703, the top of the installation groove 801 is provided with an installation inclined surface 802 that cooperates with the snap-in plate 702, and the side wall of the installation groove 801 is provided with a snap-in groove 803 for snapping the end of the snap-in plate 702.

[0033] When in use, when installing the support block 7, the brake elastic member 705 is compressed by squeezing the active cavity 701 inwardly, and the sliding block 703 enters the T-shaped slide groove 804 at the same time. After the card plate 702 can slide into the installation groove 801 by using the installation inclined surface 802, the support block 7 continues to slide downward to make the end of the card plate 702 enter the card groove 803, and the support block 7 is clamped by the cooperation of the card groove 803 and the card plate 702. At the same time, because the card plate 702 can drive the brake column 706 to enter the active cavity 701, the brake member 704 is not located in the brake groove 111 at this time. When the support block 7 is pressed down at a normal speed by the locking groove 510, the card plate 702 cannot be separated from the inside of the card groove 803. At this time, the transmission chain 106 drives the sprocket 105 to rotate until the support block 7 moves to the bottom of the sprocket 105. When the hanging box 501 falls at an excessive speed, the bottom of the hanging box 501 collides with the support block 7 at a faster speed, causing the clamping plate 702 to slide down along the inclined surface inside the clamping groove 803, thereby causing the support block 7 to separate from the clamping plate 8. At this time, under the action of the brake elastic member 705, the brake member 704 is pressed tightly inside the brake groove 111, causing the support block 7 to slide downward along the vertical brake groove 111, braking the hanging box 501 to prevent the hanging box 501 from falling.

[0034] like Figure 3 and Figure 4 As shown, two pulley plates 504 are symmetrically arranged on the side of the hanging box 501 with respect to the trapezoidal clamping plate 503, and the limiting pulleys 505 are arranged on the pulley plates 504 at equal intervals up and down through the rotating shaft. The front and rear sides of the trapezoidal clamping plate 503 are both provided with pulley grooves 506, and the limiting pulleys 505 are arranged inside the pulley grooves 506 at equal intervals up and down through the rotating shaft.

[0035] The bottom of the front and rear sides of the hanging box 501 are movably connected to the outward-opening flip door 502 through a rotating shaft. The height of the flip door 502 is greater than the gap between the hanging box 501 and the wall. When transporting electromechanical equipment to the interior of the floor, the flip door 502 is opened outward and erected on the gap. The left and right inner walls of the hanging box 501 are provided with plate grooves 508. The inside of the plate grooves 508 is provided with locking plates 509 that slide up and down. Lock grooves 510 for snapping into the lock plates 509 are provided on the left and right sides of the top of the flip door 502.

[0036] During specific use, when the hanging box 501 is lifted and lowered inside the lifting frame 1, the limiting pulley 505 is used to support it laterally inside the lifting frame 1, so as to reduce the resistance between the hanging box 501 and the lifting frame 1 and ensure good stability during the lifting process. When transporting electromechanical equipment, the locking plate 509 is disengaged from the locking groove 510 by pulling the locking plate 509 upwards, and then the flip door 502 is opened, and the flip door 502 is set on the floor, and the flip door 502 is used as a pedal to transport the electromechanical equipment.

[0037] The lifting mechanism 4 includes a balance rope 403 directly connected to the top of the hoisting box 501 and distributed in a circular array. The top of the balance rope 403 is connected together through a connecting node 402. The top of the connecting node 402 is provided with a main cable 401, and the main cable 401 is driven by a winch provided on the top of the lifting frame 1.

[0038] The specific steps and principles of using this device are as follows: First, the lifting frame 1 is connected up and down by using the reinforcement plate 2 and the wall bracket 3, and then installed on the outer wall of the building. During the installation, ensure that the counterweight block 103 is at the highest point and the drum brake mechanism is in the braking state. During normal operation, it is necessary to lift the electromechanical equipment to the specified floor. After the electromechanical equipment is loaded into the hanging box 501, Figure 4 As shown, the flip door 502 is locked inside the hanging box 501 by the locking plate 509, and the lifting mechanism 4 is driven by the winch to make the hanging box 501 rise; During the ascending process of the hanging box 501, Figure 3 As shown, the trapezoidal clamping plate 503 will first contact the support block 7 at the lowest position through the inclined surface at the top, and then, as shown in FIG. Fig.15 As shown, the pressing block 507 on the side of the hanging box 501 will lift the end of the rotating rod 601, so that the rotating rod 601 presses down the ejector rod 607, and at the same time the ejector rod 607 enters the ejector rod groove 605. After the pressing block 507 lifts the end of the rotating rod 601 to the highest position, the knocking hammer 603 contacts the lower power board 608 and is energized. At the same time, under the action of inertia, the lower power board 608 presses down the rebound airbag 610, so that when the side wall of the pressing block 507 slides along the rotating rod 601, the knocking hammer 603 and the lower power board 608 always remain in a connected state. At this time, the hammer 603 is connected to the lower power board 608 to energize the electromagnet 112. Fig.13 and Fig.14 As shown, the electromagnet 112 repels the internal magnet 100 and attracts the external magnet 113, inserting one end of the sliding column 114 into the semi-cylinder 122, so that the brake shaft 118 is separated from the brake pad 120. After the brake is released, Fig.11As shown, the weight of the counterweight block 103 is transmitted through the transmission chain 106, and the transmission chain 106 is inside the chain housing 107, so that the transmission chain 106 drives the sprocket 105 to rotate, so that the support block 7 is pressed tightly against the trapezoidal clamping plate 503, until the hanging box 501 rises to a position exceeding the support block 7, so that the support block 7 can lift the hanging box 501 to assist the hanging box 501 to move upward, thereby reducing the load of the lifting mechanism 4 and the winch, until as shown in FIG. Fig.12 As shown, the lifting plate 104 falls on the load-bearing hook 116, the counterweight block 103 no longer descends, and the support block 7 is separated from the hanging box 501; When the hanging box 501 descends normally, the hanging box 501 will first contact the top support block 7, causing the support block 7 to move downward while driving the counterweight block 103 to rise through the transmission chain 106, thereby storing gravitational potential energy. When the hanging box 501 presses down the support block 7, since the brake column 706 does not pop outward, the brake member 704 has no position inside the brake groove 111 at this time, and the support block 7 can follow the trajectory of the chain shell 107 to move to the bottom of the sprocket 105. When the support block 7 reaches the lowest position, the end of the support block 7 slides and rubs against the side of the trapezoidal clamping plate 503. When the locking groove 510 continues to descend, the clamping block 507 can contact the end of the rotating rod 601, and the rotating rod 601 is rotated by pressing down the end of the rotating rod 601 when the clamping block 507 descends. 07 and when the end of the rotating rod 601 is pressed to the lowest position, the striking hammer 603 contacts the upper power plate 611 and is energized. At the same time, the striking hammer 603 uses inertia to strike the upper counterweight plate 612 upward, and the upper counterweight plate 612 will slide upward to a certain height, and then fall down when the rotating rod 601 has not yet lost contact with the side wall of the clamping block 507, so that the striking hammer 603 and the upper power plate 611 are continuously in contact and energized, and the electromagnet 112 is energized. At this time, the electromagnet 112 repels the external magnet 113 and adsorbs the internal magnet 100, so that the sliding column 114 is pulled out from between the semi-cylinders 122, and the brake pad 120 is pressed against the brake shaft 118 under the action of the tensioning member 121 to prevent the counterweight block 103 from falling. As the hanging box 501 continues to fall, the bottom of the hanging box 501 will contact the next support block 7; When the clamping block 507 descends at an excessive speed or falls, due to the high landing speed, the bottom of the hanging box 501 collides with the supporting block 7 at a faster speed, causing the clamping plate 702 to slide down along the inclined surface inside the clamping groove 803, thereby causing the supporting block 7 to separate from the clamping plate 8. At this time, under the action of the brake elastic member 705, the brake member 704 is pressed tightly inside the brake groove 111, causing the supporting block 7 to slide downward along the vertical brake groove 111, braking the hanging box 501 to prevent the hanging box 501 from falling. At the same time, when the pressing block 507 contacts the rotating rod 601 downward, the pressing block 507 raises the striking hammer 603 at a faster speed, so that the striking hammer 603 strikes the upper power board 611 violently, which will move the upper counterweight plate 612 upward to turn on the power switch 614. The power switch 614 is connected to the electromagnet 112 inside the lifting frame 1 at the adjacent position below, so that the electromagnet 112 is energized to pull out the sliding column 114. After the sliding column 114 moves outward, its end is located directly below the support block 7. When the falling box 501 collides with the lower support block 7 with the upper support block 7, the support block 7 will also fall off the clamping plate 8 and be braked vertically downward by the brake groove 111. After braking a certain distance, the bottom of the support block 7 will fall on the sliding column 114 extending outward, and the support block 7 and the box 501 will be supported by the sliding column 114, thereby achieving the purpose of first decelerating and braking the box 501 and then stopping the descent of the box 501, which can effectively prevent the box 501 from crashing.
