Description

Technical Field

[0001] The utility model relates to the field of hydraulic lifting platforms, in particular to a sway alarm device for a hydraulic lifting platform. Background Art

[0002] The yaw usually refers to the degree of deviation of an object in a certain direction relative to its expected position or axis. The yaw amount refers to the amount of lateral movement generated by the lifting platform during the lifting process or when it is subjected to horizontal forces. The size of the yaw amount directly affects the stability and safety of the equipment. The national standard stipulates that in the case of wind speed below level 2 indoors or outdoors, the natural yaw amount of the lifting platform during the whole process from the lowest position to the highest position should not be greater than 0.5% of the maximum lifting height.

[0003] The traditional heavy hammer swinging alarm device lacks flexibility and adjustability in trigger sensitivity. This non-adjustable trigger sensitivity makes it difficult for the alarm device to adapt to different working environments and user needs. When not in use or for maintenance, the heavy hammer cannot be effectively stored. Since the heavy hammer is usually in a free hanging state, it is easily disturbed or accidentally triggered, resulting in false alarms, increasing unnecessary maintenance costs, and may also interfere with the normal operation of the platform.

[0046] Reference Figure 1-Figure 5 , a hydraulic lifting platform deflection alarm device, comprising: a lifting platform 3, used for carrying and lifting objects; a detection mechanism 4, connected to the lifting platform 3, used to detect the deflection state of the lifting platform 3, the lifting platform 3 is the main body for carrying and lifting objects, and the deflection state of the lifting platform 3 can be monitored in real time by the detection mechanism 4 connected to the lifting platform 3, ensuring that it always remains stable during operation, and effectively preventing safety accidents caused by deflection; the detection mechanism 4 comprises: a mounting seat 401, mounted on the lifting platform 3, a detection groove 402 is formed at the bottom of the mounting seat 401, and a control groove 403 is formed on the top wall of the detection groove 402; a heavy hammer 407, arranged in the detection groove 402, used to swing in response to the deflection of the lifting platform 3, the mounting seat 401, the detection groove 402 and the control groove 403 provide a stable installation environment and precise detection space for the detection mechanism 4; a winding wheel 405, connected in the control groove 403, and a connecting member 40 is connected to the winding wheel 405 6. One end of the connecting member 406 is connected to the weight 407, and the winding wheel 405 is used to realize the winding and releasing of the connecting member 406 by rotation, and control the lifting and lowering of the weight 407; multiple contact members 410 are connected in the detection groove 402, and are configured to approach or move away from the weight 407 at the same time, so as to adjust the distance between the contact member 410 and the weight 407; the alarm part 5 is connected to the detection mechanism 4, and is configured to trigger the alarm part 5 to send an alarm signal when the contact member 410 contacts the weight 407. The combined use of the winding wheel 405 and the connecting member 406 can not only control the lifting and lowering of the weight 407 by winding and releasing the connecting member 406, but also can further accurately judge the degree of deflection by the change in the position of the weight 407. The design of the contact member 410 enables the detection mechanism 4 to trigger an alarm when the weight 407 deflects to a certain position, thereby improving the accuracy and reliability of the detection. The connecting member 406 adopts a nylon rope or a nylon belt.

[0047] Reference Figure 4 and Figure 5The detection mechanism 4 also includes: a connecting seat 408, which is installed on the inner wall of the detection groove 402; a plurality of adjustment seats 409, which are installed on the connecting seat 408, and the contact member 410 is connected to one end of the adjustment seat 409; a plurality of movable grooves 414, which are opened on the mounting seat 401, and the adjustment seat 409 is connected to the movable groove 414; a plurality of screw rods 411, one end of which is connected to the adjustment seat 409, and the other end simultaneously passes through the connecting seat 408 and the mounting seat 401 and extends to the outside of the mounting seat 401; a knob 412, which is installed on the screw rod 411; a power source 404, which is installed on the side wall of the control groove 403, and the power shaft of the power source 404 is connected to the winding wheel 405, so as to provide power for the winding wheel 405; a cover plate 413, which is installed at the bottom of the mounting seat 401, and the alarm unit 5 is installed at the bottom of the cover plate 413, The cover plate 413 is used to close the detection slot 402 and provide protection for the heavy hammer 407. Through the combination of the adjustment seat 409 and the movable slot 414, the knob 412 can be turned to drive the screw 411 to rotate, and the screw 411 drives the adjustment seat 409 to move in the movable slot 414. The adjustment seat 409 can drive the contact member 410 to move, and the position of the contact member 410 can be easily adjusted to meet the needs of different deflection thresholds. The contact member 410 can be made of a copper plate or an aluminum plate. The power source 404 provides power for the winding wheel 405 to ensure that the winding and releasing process of the connecting member 406 is smoother and more reliable. The design of the winding wheel 405 makes the winding and releasing process of the connecting member 406 more controllable, further improving the accuracy and sensitivity of the detection. The power source 404 uses a servo motor and can also use a stepping motor.

[0048] Reference Figure 4 and Figure 5 The projection shape of the connecting seat 408 is a circular ring, and the projection shape of the contact piece 410 is an arc shape, which is used to be distributed around the heavy hammer 407.

[0049] Reference Figure 3 The alarm unit 5 may use an audible and visual alarm to send out sound and light signals, or a vibration alarm to send out vibration signals when the device deflects.

[0050] Reference Figure 1 and Figure 2 A movable base 1 is arranged below the lifting platform 3, for supporting the lifting platform 3 and providing a movable function; a hydraulic folding mechanism 2 is arranged between the movable base 1 and the lifting platform 3, for controlling the lifting of the lifting platform 3.

[0051] During use, the hydraulic folding mechanism 2 is used to perform lifting and lowering adjustment to reach the required working height, the screw rod 411 is adjusted by rotating the knob 412 to drive the adjustment seat 409 to move in the moving slot 414, the position of the contact piece 410 is adjusted, and a suitable deflection threshold is set. The alarm unit 5 is installed at the bottom of the cover plate 413, and it is ensured that the cover plate 413 closes the detection slot 402 to provide protection for the heavy hammer 407. The lifting platform 3 begins to carry and lift objects and enters the working state. The detection mechanism 4 begins to monitor the deflection state of the lifting platform 3 in real time. If the lifting platform 3 deflects during operation, the heavy hammer 407 will swing in response to the deflection. When the heavy hammer 407 swings to a certain position due to the deflection and contacts the contact piece 410, the alarm unit 5 is installed at the bottom of the cover plate 413. The detection slot 402 is closed to provide protection for the heavy hammer 407. When the contact 410 is in contact, the alarm unit 5 will be triggered, and the alarm unit 5 will send out an audible and visual alarm signal or a vibration signal to alert the operator. After the operator hears or feels the alarm signal, he should immediately stop the operation of the lifting platform 3 and check the status of the lifting platform 3. According to the inspection results, the operator can adjust the position of the lifting platform 3 or take other measures to eliminate the deflection and restore the normal operation of the lifting platform 3. When the equipment is not in use, the power source 404 drives the winding wheel 405 to rotate. The rotation of the winding wheel 405 will control the winding or release of the connecting member 406, control the lifting and lowering of the weight 407, and detach the weight 407 from the multiple contact members 410 to avoid contact with the contact members 410.

[0052] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0053] By adjusting the positions of the contact member 410 and the weight 407 , the trigger sensitivity can be flexibly adjusted as needed to adapt to different working environments and user needs.

[0054] The mounting base 401, the detection slot 402 and the cover plate 413 provide a closed and protected space for the weight 407. When not in use or for maintenance, the weight 407 can be effectively stored to prevent external interference or accidental touch.

[0055] The use of the knob 412 and the screw rod 411 makes it simple and intuitive to adjust the position of the contact member 410. The operator only needs to rotate the knob 412 to move the contact member 410, and the required deflection threshold can be set quickly and conveniently.
