Description

Technical Field

[0001] The utility model relates to the technical field of elevator car body balancing, in particular to a hidden balancing block structure for an elevator car bottom. Background Art

[0002] With the continuous improvement of construction standards, high-rise buildings are being built in more and more places. The use of high-rise buildings cannot be achieved without the assistance of car elevators. A car elevator is an elevator equipment with a car. The interior of the car can be used to carry goods and transport people to the corresponding building floors of the house, effectively improving the utilization rate of space and saving land area. During the installation of the car elevator, a balance block will be installed at the bottom of the car. Generally, iron blocks or weighted cement blocks are used for installation. After the balance block is installed, the operation of the car elevator can be balanced, making the operation of the car elevator more stable, thereby effectively avoiding the discomfort caused by shaking to passengers.

[0003] Traditional undercarriage counterweight structures typically use external brackets to mount the counterweights at the bottom of a car-type elevator. This is not only visually unsightly, but the brackets used to install the counterweights also increase costs. Therefore, we propose a hidden undercarriage counterweight structure for elevators to address these issues. Utility Model Content

[0004] The purpose of the present utility model is to provide a hidden balancing block structure for an elevator car floor, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a hidden balancing block structure for the elevator car bottom, including an elevator car body, a reinforcing rib frame is provided at the bottom end of the interior of the elevator car body, a weighted cement block is installed inside the reinforcing rib frame, a fixing hole is provided inside the weighted cement block, and a fixing part is installed inside the fixing hole.

[0006] Preferably, the cross section of the weighted cement block matches the cross section of the reinforcement frame, and a snap-fit structure is formed between the weighted cement block and the reinforcement frame.

[0007] Preferably, four groups of fixing members are provided, and the four groups of fixing members are symmetrically distributed about the central axis of the weighted cement block.

[0008] Preferably, fixed clamping rods are hingedly installed on both sides of the top end of one end of the reinforcement frame, connecting blocks are fixed on the left and right sides of one end of the reinforcement frame, and fixed hooks are fixed on one end of the connecting blocks.

[0009] Preferably, two groups of fixed clamping rods and two groups of fixed clamping hooks are provided, and a clamping structure is formed between the fixed clamping rods and the fixed clamping hooks.

[0010] Preferably, a pull-out plate is movably provided at the bottom end of the weighted cement block, and an annular connecting ring is installed at one end of the pull-out plate.

[0011] Preferably, the cross section of the pull-out plate body is equal to the cross section of the weighted cement block, and the pull-out plate body and the weighted cement block are matched with each other.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the hidden balancing block structure for the elevator car floor not only makes the bottom end hidden inside the car floor more beautiful, but also saves costs to a certain extent, stabilizes the balancing block, makes its installation inside the reinforcement frame more stable, and facilitates the removal and replacement of damaged weight-added cement blocks, thereby achieving better use effect;

[0013] (1) A reinforcing rib frame is provided, which is provided at the bottom end of the interior of the elevator car body. The weighted cement block is then inserted into the interior of the reinforcing rib frame to install the weighted cement block at the bottom end of the interior of the elevator car body. The weighted cement block is fixed with four sets of fixing parts, thereby achieving a more beautiful installation of the balance block structure inside the car body. Compared with the traditional method of requiring an external bracket to install the weighted cement block, the cost is saved to a certain extent.

[0014] (2) By providing components such as a fixing hook, a fixing rod and a connecting block, after the weighted cement block is installed inside the reinforcing rib frame, the fixing rod can be flipped over with the cooperation of the above components to make it engage with the inside of the fixing hook. After a limit is formed at one end of the reinforcing rib frame, the installation of the weighted cement block inside the reinforcing rib frame is more stable. In addition, the limit of the fixing rod can prevent the weighted cement block from moving outward during the process of the fixing member being screwed into the inside of the weighted cement block, thereby achieving a better use effect.

[0015] (3) By providing components such as an annular connecting ring and a pull-out plate, when the weighted cement block is installed at the bottom end of the interior of the car to increase the counterweight, if the weighted cement block is cracked and needs to be replaced as the use time increases, the pull-out plate can be pulled outward by holding the annular connecting ring so that the cracked weighted cement block above the pull-out plate can be more conveniently moved out from the interior of the reinforcement frame for replacement, making it easier to take out the damaged weighted cement block for replacement, and more convenient to use.

[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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-4 , a hidden balancing block structure for the bottom of an elevator car comprises an elevator car body 1, a reinforcing rib frame 2 is provided at the bottom end of the interior of the elevator car body 1, a weight-added cement block 7 is installed inside the reinforcing rib frame 2, a fixing hole 3 is provided inside the weight-added cement block 7, and a fixing piece 5 is installed inside the fixing hole 3, the cross section of the weight-added cement block 7 matches the cross section of the reinforcing rib frame 2, and a snap-fit structure is formed between the weight-added cement block 7 and the reinforcing rib frame 2, which has a better weight-added effect on the elevator car body 1, and four groups of fixing pieces 5 are provided, and the four groups of fixing pieces 5 are symmetrically distributed about the central axis of the weight-added cement block 7. The symmetrically distributed fixing pieces 5 make the installation of the weight-added cement block 7 inside the reinforcing rib frame 2 more stable;

[0023] Specifically, if Figure 1 and Figure 3 As shown, the reinforcement frame 2 is fixed to the bottom end of the elevator car body 1, and then the weighted cement block 7 is inserted into the interior of the reinforcement frame 2 so that the weighted cement block 7 is inserted into the bottom end of the elevator car body 1. Then, the fixing piece 5 is taken out and passed through the fixing hole 3 inside the weighted cement block 7 and screwed into the interior of the elevator car body 1 to install the reinforcement frame 2. Then, the elevator car body 1 is counterweighted by the weighted cement block 7 to balance it.

[0024] Embodiment 2: Both sides of the top end of the reinforcement frame 2 are hingedly installed with fixed clamping rods 9, and the left and right sides of one end of the reinforcement frame 2 are fixed with connecting blocks 10, and one end of the connecting block 10 is fixed with a fixed hook 8. Two groups of fixed clamping rods 9 and fixed hooks 8 are provided, and a clamping structure is formed between the fixed clamping rods 9 and the fixed hooks 8. The design of the clamping structure has a better limiting effect on the weighted cement block 7 inserted into the interior of the reinforcement frame 2, and the limiting effect is more stable.

[0025] Specifically, if Figure 1 and Figure 2 As shown, after the weighted cement block 7 is inserted into the interior of the reinforcement frame 2, the fixed clamping rod 9 is flipped in turn to make it engage with the interior of the fixed hook 8, and the weighted cement block 7 installed in the interior of the reinforcement frame 2 is limited, so that the weighted cement block 7 is stably installed in the interior of the reinforcement frame 2 to avoid moving outward.

[0026] Embodiment 3: The bottom end of the weighted cement block 7 is movably provided with a pull-out plate 6, and one end of the pull-out plate 6 is installed with an annular connecting ring 4. The cross section of the pull-out plate 6 is equal to the cross section of the weighted cement block 7. The pull-out plate 6 is adapted to the weighted cement block 7, so that the damaged weighted cement block 7 can be completely removed, and the replacement of the weighted cement block 7 is more convenient.

[0027] Specifically, if Figure 1 and Figure 4 As shown, when the weighted cement block 7 is cracked and needs to be replaced, the annular connecting ring 4 is held and the pull-out plate 6 is pulled to pull out the cracked weighted cement block 7 inside the reinforcement frame 2, thereby preventing the cracked weighted cement block 7 from being stuck inside the reinforcement frame 2 and being difficult to remove.

[0028] Working principle: When the present invention is in use, a corresponding groove is opened at the bottom end of the interior of the elevator car body 1, and a reinforcing rib frame 2 is installed inside the groove. After the reinforcing rib frame 2 is inserted into the interior of the weighted cement block 7, it is used to increase the balance of the elevator car body 1. After the weighted cement block 7 is inserted into the interior of the reinforcing rib frame 2, the fixing clamping rod 9 is turned over in turn to make it engage with the interior of the fixing clamping hook 8, and the weighted cement block 7 installed in the interior of the reinforcing rib frame 2 is limited, and the fixing piece 5 is taken out to pass through the weighted water The fixing hole 3 inside the mud block 7 is screwed into the interior of the elevator car body 1 to install the reinforcement frame 2. Later, if the weighted cement block 7 is cracked and needs to be replaced as the use time increases, the fixing clamping rod 9 is rotated in the opposite direction to disengage it from the inside of the fixing hook 8. Then, the cracked weighted cement block 7 inside the reinforcement frame 2 is pulled out by holding the annular connecting ring 4 and pulling the pull-out plate 6. Then, a new weighted cement block 7 is taken out and inserted into the interior of the reinforcement frame 2 to continue balancing the elevator car body 1.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
