Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a counterweight balancing component for hoists. Background Technology

[0002] In modern industrial production, construction, and logistics, hoists are key equipment for vertically lifting materials or personnel, and their operational stability and energy efficiency have always been core concerns in the industry. The working principle of a hoist mainly relies on a drive motor that pulls a rope to move a lifting platform to complete the lifting action. The counterweight is designed to balance the load on the lifting platform, reducing the output load on the drive motor, thereby improving the safety and energy efficiency of the equipment.

[0003] However, in practical applications, the weight of materials or the number of personnel carried by the lifting platform are often in a dynamic state. Traditional counterweight balancing methods mostly use fixed counterweight blocks, which are difficult to adjust flexibly according to the real-time load of the lifting platform. If the counterweight is too light, the drive motor needs to output more power to overcome the gravity of the lifting platform, which will not only increase energy consumption, but also aggravate the wear of the motor and the pull rope, shortening the service life of the equipment. If the counterweight is too heavy, the lifting platform will be subjected to additional tension when it rises, which may lead to loss of control of the lifting speed and pose a serious safety hazard.

[0004] To address the aforementioned issues, we propose a counterweight balancing assembly for hoists. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a counterweight balancing component for a hoist.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A counterweight balancing assembly for a hoist includes a base, a vertical support structure fixedly mounted on the upper side of the base, slots symmetrically fixedly mounted on both sides of the vertical support structure, a counterweight platform and a lifting platform slidably connected to the sides of the slots respectively, a first pull rope fixedly connected to the upper side of the vertical support structure, and a balancing tension detection assembly disposed on the first pull rope; the balancing tension detection assembly includes a structural cylinder, a detection column disposed inside the structural cylinder, the first pull rope slidingly passing through the inner side of the structural cylinder, the end of the first pull rope being fixedly connected to the detection column, a plurality of tension detection strain gauges fixedly mounted on the outer wall of the detection column, an LED light, a control circuit board and a button battery compartment being sequentially fixedly mounted on the outer wall of the structural cylinder, a wireless signal transmission antenna fixedly mounted on the upper side of the control circuit board, and a button battery being installed inside the button battery compartment.

[0008] Furthermore, a controller is fixedly installed on the side wall of the vertical support structure, and a wireless signal antenna is fixedly installed on the controller.

[0009] Furthermore, a support is fixedly installed on the upper side of the vertical support structure, a rotating shaft is rotatably installed on the support, and a first winch and a second winch are fixedly installed on the rotating shaft in sequence.

[0010] Furthermore, the first pull rope is wound onto the upper side of the first winch.

[0011] Furthermore, a second pull rope is fixedly connected to the upper side of the counterweight platform. The second pull rope is wound around the second winch, and the first pull rope and the second pull rope are wound in opposite directions.

[0012] Furthermore, a large gear is fixedly installed on the outer wall of the rotating shaft, a drive motor is provided on the lower side of the large gear, the drive motor is fixedly installed on the upper side of the vertical support structure, and a small gear is fixedly installed on the output end of the drive motor, the small gear meshing with the large gear.

[0013] Furthermore, the large gear, small gear, and drive motor are covered with protective covers.

[0014] Compared with related technologies, the counterweight balancing component for a hoist proposed in this utility model has the following advantages:

[0015] In this invention, a counterweight balancing component for a hoist is described. This component includes a tension detection component embedded in the pull rope of the hoisting platform. Several strain gauges in the detection column monitor the tension in the pull rope. A control circuit board processes the tension values ​​from these strain gauges, converting them into electrical signals, which are then transmitted to a wireless signal antenna. The wireless antenna transmits the signals to a controller, which averages the monitored tension values ​​to improve accuracy. Since the weight of the counterweight platform is constant, the controller subtracts the weight of the counterweight platform from this tension value, and then subtracts the recommended control amount for the weight difference. This results in a suggested increase in weight on the counterweight platform, leading to better balance, reduced energy consumption of the drive motor, smoother daily operation of the counterweight platform, and improved safety.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Reference Figures 1-5 A counterweight balancing assembly for a hoist includes a base 1, a vertical support structure 2 fixedly mounted on the upper side of the base 1, slots 5 symmetrically fixedly mounted on both sides of the vertical support structure 2, a counterweight platform 7 and a lifting platform 6 slidably connected to the sides of the slots 5 respectively, a first pull rope 8 fixedly connected to the upper side of the vertical support structure 2, and a balancing tension detection assembly 9 provided on the first pull rope 8; the balancing tension detection assembly 9 includes a structural cylinder 91, a detection column 96 provided inside the structural cylinder 91, the first pull rope 8 slidingly passing through to the inside of the structural cylinder 91, the end of the first pull rope 8 being fixedly connected to the detection column 96, a plurality of tension detection strain gauges 97 fixedly mounted on the outer wall of the detection column 96, an LED light 92, a control circuit board 93 and a button battery compartment 95 sequentially fixedly mounted on the outer wall of the structural cylinder 91, a wireless signal transmission antenna 94 fixedly mounted on the upper side of the control circuit board 93, and a button battery installed inside the button battery compartment 95.

[0024] With the above configuration, the button battery is used to provide power to the components in the balance tension detection assembly 9. When the button battery power is low, the control circuit board 93 controls the LED light 92 to light up, indicating that the power is low.

[0025] In this method, a controller 3 is fixedly installed on the side wall of the vertical support structure 2, and a wireless signal antenna 4 is fixedly installed on the controller 3.

[0026] With the above configuration, the wireless signal antenna 4 and the wireless signal transmission antenna 94 exchange and transmit wireless signals.

[0027] In this configuration, a support 10 is fixedly installed on the upper side of the vertical support structure 2, and a rotating shaft 11 is rotatably installed on the support 10. A first winch 12 and a second winch 13 are fixedly installed on the rotating shaft 11 in sequence. A large gear 16 is fixedly installed on the outer wall of the rotating shaft 11, and a drive motor 17 is provided on the lower side of the large gear 16. The drive motor 17 is fixedly installed on the upper side of the vertical support structure 2, and a small gear is fixedly installed on the output end of the drive motor 17. The small gear meshes with the large gear 16. A protective cover 14 is provided on the outer side of the large gear 16, the small gear, and the drive motor 17. A first pull rope 8 is wound on the upper side of the first winch 12, and a second pull rope 15 is fixedly connected to the upper side of the counterweight platform 7. The second pull rope 15 is wound on the second winch 13, and the first pull rope 8 and the second pull rope 15 are wound in opposite directions.

[0028] With the above configuration, the drive motor 17 is started to drive the rotating shaft 11 to rotate, which in turn drives the two stranding reels to rotate synchronously. Since the stranding directions of the first reel 12 and the second reel 13 are opposite, when the first reel 12 and the second reel 13 rotate synchronously, one side is engaged in winding and the other side is engaged in unwinding. This causes the lifting platform 6 and the counterweight platform 7 to move in opposite directions, and the torque applied to the stranding reels by the pull rope is opposite, forming a balancing and canceling effect. As a result, only a small torque is needed on the rotating shaft to drive the lifting platform 6 to move up and down, reducing the output power of the drive motor 17 and reducing energy consumption.

[0029] The working principle of the counterweight balancing component for a hoist provided by this utility model is as follows:

[0030] In operation, the counterweight balancing assembly for the hoist first places the material or personnel to be hoisted onto the hoisting platform 6. Then, the drive motor 17 is started, and the output of the drive motor 17 drives the pinion to rotate. The pinion meshes with the large gear 16, thereby driving the large gear 16 and the rotating shaft 11 to rotate. Since the first winch 12 and the second winch 13 are fixedly mounted on the rotating shaft 11, and the first pull rope 8 and the second pull rope 15 are wound in opposite directions, when the rotating shaft 11 rotates, the first winch 12 winds up or releases the first pull rope 8, while the second winch 13 simultaneously releases or winds up the second pull rope 15, causing the hoisting platform 6 and the counterweight platform 7 to move upward or downward respectively under the guidance of the slot 5.

[0031] During daily operation, the balance tension detection component 9 monitors the tension change of the first pull rope 8 in real time. The first pull rope 8 slides through the inner side of the structural cylinder 91 and is fixedly connected to the detection column 96. When the first pull rope 8 is subjected to force, it will cause the detection column 96 to produce a slight deformation. Several tension detection strain gauges 97 on the outer wall of the detection column 96 sense the deformation and convert it into an electrical signal. The control circuit board 93 processes these electrical signals and converts them into tension detection values. At the same time, the button battery in the button battery compartment 95 powers the control circuit board 93, LED lights 92 and other components.

[0032] The control circuit board sends the processed tensile force detection value through the wireless signal transmission antenna 94. The wireless signal antenna 4 of the controller 3 on the side wall of the vertical support structure 2 receives the signal. The controller 3 averages the monitored tensile force values ​​of several tensile force detection strain gauges 97 to improve detection accuracy. Since the weight of the counterweight platform 7 is a fixed value, the controller 3 subtracts the weight of the counterweight platform 7 from the average tensile force value, and then subtracts the recommended control amount of the weight difference to obtain the recommended counterweight weight value to be added to the counterweight platform 7.

[0033] According to the prompts of the controller 3, the staff can add the corresponding weight of the counterweight block to the counterweight platform 7 to make the counterweight more balanced. When the button battery power is low, the control circuit board 93 controls the LED light 92 to light up, prompting the battery to be replaced.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
