Description

Technical Field

[0001] This utility model relates to the field of elevator counterweights, specifically an assembled elevator counterweight. Background Technology

[0002] The elevator counterweight is a balancing system that uses a counterweight device to balance the weight of the car and part of the load. Its core consists of a counterweight frame and counterweight blocks, which are installed in the hoistway to form a dynamic balance with the car. The optimal balance is achieved when the car load reaches 40% to 50% of the rated load. The system reduces the power loss of the motor through the linkage of the traction rope. When the mass difference between the car and the counterweight is less than 50% of the rated load, the friction and wear between the wire rope and the sheave can be reduced.

[0003] Patent application number 202223531349.7 discloses an elevator counterweight, comprising a plastic shell, cement filler, and reinforcement. The plastic shell is elongated, with "U"-shaped ends at both transverse ends. Two semi-circular notches for transport are located at the bottom of both the front and rear sides of the plastic shell, symmetrically positioned along the centerline. The reinforcement is laid inside the plastic shell along its length, extending to the "U"-shaped ends at both ends. A filling port is located at one end of the plastic shell. The surface of the plastic shell is coated with an anti-corrosion paint. This elevator counterweight has the advantages of stable material, convenient transport, and strong corrosion resistance.

[0004] However, in practical applications, traditional counterweights are heavy, and when installing them on the frame, workers need to carry them back and forth, which requires a lot of physical strength, is inconvenient for counterweight assembly, and reduces the practicality of the device. For example, when workers assemble the counterweight, the entire counterweight needs to be moved onto the frame. Because the counterweight is heavy, it is very difficult to move, requiring multiple workers to move it together or to use tools. This makes assembly inconvenient and reduces the practicality of the device. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an assembled elevator counterweight to solve the technical problem that the current counterweight is too heavy, and when installing the counterweight on the frame, workers need to carry it back and forth, which requires a lot of physical strength, is inconvenient for counterweight assembly, and reduces the practicality of the device.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a modular elevator counterweight is designed, including a first counterweight, a positioning groove is provided on one side of the first counterweight, a positioning rod is symmetrically fixed at the bottom of the positioning groove, an installation groove is provided on the top of the first counterweight, a second counterweight is connected to one side of the first counterweight, a positioning block is fixed to one side of the second counterweight, a positioning hole is symmetrically provided through the top of the positioning block, a fixing mechanism is connected inside the installation groove, and a limit mechanism is connected to one side of the installation groove.

[0007] In this design, the fixed mechanism facilitates the connection of the first and second pairs of weights, allowing for separate handling of each pair before final assembly. This avoids handling excessively heavy objects at once, reducing labor costs and improving the practicality of the device. The limiting mechanism restricts the fixed mechanism, preventing it from loosening and ensuring assembly stability.

[0008] Preferably, the fixing mechanism includes a slide rod fixed between the two sides of the mounting groove, a sliding seat symmetrically sliding on the outer side of the slide rod, a return spring fixed between the opposite sides of the two sliding seats, a pull rod fixed on the top of the sliding seat, a connecting rod rotating inside the sliding seat, an insert block penetrating through the middle of one side of the mounting groove, and the insert block slidably connected to the first counterweight block, a connecting plate fixed on one side of the insert block, a connecting seat symmetrically fixed on one side of the connecting plate, and a slot opened in the middle of one side of the positioning block.

[0009] In practical applications, during assembly, one person first moves the first pair of weights onto the frame, pulls the lever to bring the two sliding seats closer together, compresses the return spring, and simultaneously deflects the connecting rod, causing the connecting seat to move, which in turn causes the connecting plate to move the insert block. Then, another person moves the second pair of weights onto the frame, positioning the positioning block in the positioning groove, inserting the positioning rod into the positioning hole, and loosening the lever. The return spring then resets the sliding seat, thereby resetting the insert block, which is then embedded in the slot, completing the assembly. This method facilitates the separate handling of the first and second pairs of weights before final assembly, avoiding the need to move excessively heavy objects at once, reducing the workload of handling, simplifying assembly, and improving the practicality of the device.

[0010] Preferably, the fixing mechanism further includes sliders fixed to the middle of both sides of the connecting plate, and the two sides of the mounting groove are provided with sliding grooves.

[0011] Preferably, the slider slides inside the groove, and the outer sidewall of the slider is in contact with the inner sidewall of the groove.

[0012] In practical applications, when the connecting plate moves, the slider moves inside the groove, thereby limiting the connecting plate and ensuring that it can only move in a straight line.

[0013] Preferably, the return spring is sleeved on the outside of the slide rod, and one end of the connecting rod rotates inside the connecting seat.

[0014] In practical applications, when the sliding seat moves, the return spring is compressed. When the pull rod is loosened, the return spring can be used to reset the sliding seat. When the sliding seat moves, the connecting rod is deflected, causing the connecting seat to move.

[0015] Preferably, the limiting mechanism includes a mounting plate fixed to the top of one side of the mounting groove, a screw rod being connected through the middle of the top of the mounting plate and rotatably connected to the mounting plate, a knob being fixed to the top of the screw rod, a threaded cylinder being screwed to the outside of the screw rod, a T-shaped plate being fixed to the bottom of the threaded cylinder, a sliding plate being symmetrically fixed to the outside of the threaded cylinder, limiting rods being symmetrically fixed to the bottom of the mounting plate, a screw hole being opened through the top edge of the mounting plate, and a fastening bolt being connected through the top edge of the knob.

[0016] In practical applications, after the first and second pairs of weights are assembled, the knob is turned to drive the screw to rotate. With the cooperation of the sliding plate and the limiting rod, the screw rotates and drives the threaded cylinder to rise, causing the T-shaped plate to rise. This allows the two sides of the T-shaped plate to fit against the opposite sides of the two sliding seats. Then, the fastening bolts are screwed into the screw holes to fix the knob and limit the sliding seats to prevent them from moving. This ensures the stable assembly of the first and second pairs of weights, prevents loosening, and improves the stability of the device.

[0017] Preferably, the sliding plate slides on the outside of the limiting rod, and a baffle is fixed at the bottom end of the limiting rod.

[0018] In practical applications, the screw cylinder is limited by the cooperation of the limit rod and the slide plate, so that the screw cylinder can only move in a straight line, and the baffle is used to prevent the slide plate from disengaging from the limit rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the setting of a fixing mechanism, allows for assembly in which one person first moves the first pair of weights onto the frame, pulls the pull rod to bring the two sliding seats closer together, compresses the return spring, and simultaneously deflects the connecting rod, causing the connecting seat to move, which in turn causes the connecting plate to move the insert block. Then, another person moves the second pair of weights onto the frame, positioning the positioning block in the positioning groove, inserting the positioning rod into the positioning hole, and loosening the pull rod. Through the reset of the return spring, the sliding seat is reset, thereby resetting the insert block, which is then embedded in the slot, completing the assembly. This facilitates the separate handling of the first and second pairs of weights before final assembly, avoiding the need to move excessively heavy objects at once, reducing the workload of handling, simplifying assembly, and improving the practicality of the device.

[0020] 2. This utility model, through the setting of a limiting mechanism, after the first and second counterweights are assembled, rotates the knob to drive the screw to rotate. Utilizing the cooperation of the sliding plate and the limiting rod, the screw rotation drives the threaded cylinder to rise, causing the T-shaped plate to rise and the two sides of the T-shaped plate to fit against the opposite sides of the two sliding seats. Then, the fastening bolt is screwed into the screw hole to fix the knob and limit the sliding seats to prevent them from moving, thereby ensuring the stable assembly of the first and second counterweights, preventing loosening of the assembly, and improving the stability of the device.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A modular elevator counterweight, see [link / reference] Figures 1 to 5 The device includes a first pair of weights 1, with a positioning groove 101 on one side of the first pair of weights 1. Positioning rods 102 are symmetrically fixed at the bottom of the positioning groove 101. An installation groove 103 is provided on the top of the first pair of weights 1. A second pair of weights 2 is connected to one side of the first pair of weights 1. A positioning block 201 is fixed to one side of the second pair of weights 2. Positioning holes 202 are symmetrically provided through the top of the positioning block 201. A fixing mechanism 3 is connected inside the installation groove 103. A limiting mechanism 4 is connected to one side of the installation groove 103. The fixing mechanism 3 facilitates the connection of the first pair of weights 1 and the second pair of weights 2, making it convenient to transport the first pair of weights 1 and the second pair of weights 2 separately before assembly. This avoids transporting excessively heavy objects at once, reduces the amount of labor involved in transporting, facilitates assembly, and improves the practicality of the device. The limiting mechanism 4 limits the fixing mechanism 3, preventing it from loosening and ensuring the stability of the assembly.

[0024] For details, see Figure 2 and Figure 3The fixing mechanism 3 includes a slide rod 301 fixed between the two sides of the mounting groove 103. A sliding seat 302 slides symmetrically on the outer side of the slide rod 301. A return spring 303 is fixed between the opposite sides of the two sliding seats 302. A pull rod 304 is fixed to the top of the sliding seat 302. A connecting rod 305 rotates inside the sliding seat 302. An insert block 306 is connected through the middle of one side of the mounting groove 103, and the insert block 306 is slidably connected to the first pair of counterweights 1. A connecting plate 307 is fixed to one side of the insert block 306, and a connecting seat 308 is symmetrically fixed to one side of the connecting plate 307. A slot 309 is provided in the middle of one side of the positioning block 201. The fixing mechanism 3 also includes a slider 310 fixed to the middle of both sides of the connecting plate 307. A sliding groove 311 is provided on both sides of the mounting groove 103. The slider 310 slides inside the sliding groove 311, and the outer wall of the slider 310 is in contact with the inner wall of the sliding groove 311. The return spring 303 is sleeved... On the outside of the slide bar 301, one end of the connecting rod 305 rotates inside the connecting seat 308. During assembly, one person first moves the first pair of weights 1 onto the frame, pulls the pull rod 304 to bring the two sliding seats 302 closer together, squeezing the return spring 303, and at the same time, the connecting rod 305 deflects, causing the connecting seat 308 to move, and the connecting plate 307 to move the insert block 306. Then, another person moves the second pair of weights 2 onto the frame, so that the positioning block 201 is located in the positioning groove 101, the positioning rod 102 is inserted into the positioning hole 202, the pull rod 304 is loosened, and the sliding seat 302 is reset by the reset spring 303, thereby resetting the insert block 306, so that the insert block 306 is embedded in the slot 309, completing the assembly. This makes it convenient to move the first pair of weights 1 and the second pair of weights 2 separately, and then assemble them, avoiding the need to move excessively heavy objects at once, reducing the amount of labor involved in moving, facilitating assembly, and improving the practicality of the device.

[0025] It is worth noting that, see Figure 4 and Figure 5The limiting mechanism 4 includes a mounting plate 401 fixed to the top of one side of the mounting groove 103. A screw 402 is connected through the middle of the top of the mounting plate 401, and the screw 402 is rotatably connected to the mounting plate 401. A knob 403 is fixed to the top of the screw 402. A threaded cylinder 404 is screwed to the outside of the screw 402. A T-shaped plate 405 is fixed to the bottom of the threaded cylinder 404. A sliding plate 406 is symmetrically fixed to the outside of the threaded cylinder 404. Limiting rods 407 are symmetrically fixed to the bottom of the mounting plate 401. A screw hole 408 is opened through the top edge of the mounting plate 401. A fastening bolt 409 is connected through the top edge of the knob 403. The sliding plate 406 slides on the limiting rod. On the outside of 407, a baffle is fixed to the bottom end of the limiting rod 407. After the first pair of weights 1 and the second pair of weights 2 are assembled, the knob 403 is turned to drive the screw 402 to rotate. With the cooperation of the sliding plate 406 and the limiting rod 407, the screw 402 rotates and drives the threaded cylinder 404 to rise, so that the T-shaped plate 405 rises and the two sides of the T-shaped plate 405 fit against the opposite sides of the two sliding seats 302. Then, the fastening bolt 409 is screwed into the screw hole 408 to fix the knob 403 and limit the sliding seat 302 to prevent the sliding seat 302 from moving, thereby ensuring the stable assembly of the first pair of weights 1 and the second pair of weights 2, preventing loosening of the assembly, and improving the stability of the device.

[0026] In practical use, when installing the counterweights, the workers move the first counterweight 1 and the second counterweight 2 onto the counterweight frame respectively. Then, the fixing mechanism 3 is used to assemble the first counterweight 1 and the second counterweight 2, thereby avoiding the need to move excessively heavy objects at once, reducing the workload, facilitating transportation and installation, and improving the practicality of the device.
