Description

Technical Field

[0001] This utility model relates to the field of door and window processing equipment technology, and in particular to a mobile lifting platform for door and window processing. Background Technology

[0002] In the door and window manufacturing industry, lifting platforms, as key auxiliary equipment, are widely used in processes such as profile cutting, drilling, and assembly. They are primarily used to support workpieces and adjust their processing height to accommodate the different work habits and process requirements of various operators. With the increasing diversification and customization of door and window products, the processing site places higher demands on the flexibility, stability, and ease of operation of equipment. Traditional fixed workbenches are insufficient to meet the processing needs of workpieces with varying heights and sizes, while ordinary mobile platforms, although possessing displacement capabilities, are prone to swaying during operation, affecting processing accuracy.

[0003] Most existing mobile lifting platforms rely on independent casters or manually detachable outriggers for movement and fixation, resulting in cumbersome operation, low switching efficiency, and the need for repeated leveling adjustments after movement, severely impacting work rhythm. Furthermore, most platforms lack flexible workpiece positioning, making them unsuitable for door and window profiles of varying lengths. Their clamping mechanisms are also mostly fixed designs, hindering rapid clamping and release. These issues lead to operational inconvenience, inaccurate positioning, and poor safety in practical use.

[0004] Therefore, it is necessary to design a mobile lifting platform for door and window processing to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing mobile lifting platforms in door and window processing applications, such as poor workpiece adaptability and inconvenient clamping, this utility model provides a mobile lifting platform for door and window processing.

[0006] The technical solution is as follows: A mobile lifting platform for door and window processing includes a bracket, a motor, a lead screw, a lifting plate, a processing table, fixed blocks, a pedal, a push rod, a locking block, a connecting block, a wedge block, and casters. A motor with its output shaft facing downwards is mounted on the front top of the bracket. The motor's output shaft passes through the top of the bracket and is fixedly connected to the lead screw. The lower end of the lead screw is rotatably connected to the bottom of the bracket. A lifting plate is threaded onto the lead screw. The rear sides of the lifting plate are slidably connected to the bracket. A processing table is fixedly connected to the lifting plate. Two fixed blocks are fixedly connected to the left and right sides of the bracket, respectively. Sliding holes are provided on the outer sides of the fixed blocks. The pedal passes through the sliding holes and slides with them. A push rod is fixedly connected to the lower part of the pedal. The lower part of the rod has a wedge-shaped surface. The locking block is sleeved around the fixed block and the push rod. The side of the locking block facing the fixed block has a sliding groove. The inner side of the fixed block is fixedly connected to a limit block. The locking block slides with the limit block through the sliding groove. The lower part of the fixed block has locking grooves on both the front and rear sides. The lower part of the locking block can slide into the locking groove of the fixed block. The front and rear sides of the push rod are respectively provided with two vertically arranged limit posts. The locking block is located between the two limit posts. The lower outer side of the fixed block is rotatably connected to a connecting block. The side of the connecting block opposite to the push rod is fixedly connected to a wedge-shaped block. The wedge-shaped block is adapted to the wedge-shaped surface of the push rod. The outer side of the connecting block is equipped with a caster wheel. The front and rear sides of the connecting block have locking grooves that cooperate with the locking block.

[0007] Furthermore, it also includes a mounting plate, a sliding frame, and a pull rod. The mounting plate is fixedly connected to the bottom of the processing table, and a sliding frame is slidably connected between the bottom of the processing table and the mounting plate. A pull rod is fixedly connected to the front side of the sliding frame.

[0008] Furthermore, it also includes a spring, with a spring connecting the rear end of the sliding frame to the front end of the mounting plate.

[0009] Furthermore, it also includes upright plates and screws. Upright plates are fixedly connected to the left and right sides of the lifting plate, and two screws are threadedly connected to the top left and right sides of the upright plates respectively.

[0010] Furthermore, it also includes a knob, which is fixedly connected to the top of the screw.

[0011] Furthermore, it also includes a pressure block, which is fixedly connected to the bottom of the screw.

[0012] The present invention has the following advantages: 1. The present invention, by setting a push rod driven by a pedal, a connecting block rotatably connected to the bracket, and a universal wheel, realizes the conversion of the bracket off the ground and the universal wheel on the ground by stepping, which significantly improves the switching efficiency of the equipment between the fixed state and the moving state.

[0013] 2. This utility model sets a vertical limiting post on the push rod and slides the locking block between the fixed block and the push rod. During the downward movement of the push rod, the limiting post pushes the locking block from the locking groove of the fixed block into the locking groove of the connecting block, preventing it from rebounding or swinging. This effectively prevents the universal wheel from shaking due to vibration during movement and improves the stability and safety of the equipment operation.

[0014] 3. This utility model achieves rapid extension and return by setting a sliding frame that can slide back and forth on the processing table, and cooperating with a pull rod and a return spring; at the same time, combined with the vertical adjustment function of the lifting plate and the clamping structure of the screw driving the pressure block to clamp the workpiece, it realizes multi-dimensional positioning and reliable fixation of door and window workpieces of different sizes, and enhances the versatility and processing adaptability of the equipment.

Detailed Implementation

[0023] Example: A mobile lifting platform for door and window processing, such as... Figures 1-7As shown, the system includes a bracket 1, a motor 2, a lead screw 3, a lifting plate 4, a processing table 5, a fixing block 6, a pedal 7, a push rod 8, a locking block 9, a connecting block 10, a wedge block 11, and casters 12. A motor 2 with its output shaft facing downwards is mounted on the top front side of the bracket 1. The output shaft of the motor 2 passes through the top of the bracket 1 and is connected to the lead screw 3 by welding. The lower end of the lead screw 3 is rotatably connected to the bottom of the bracket 1. A lifting plate 4 is threaded onto the lead screw 3. The rear sides of the lifting plate 4 are slidably connected to the bracket 1 via sliding rods. A processing table 5 is bolted to the lifting plate 4. The frame 1 has two fixing blocks 6 connected to its left and right sides by bolts. The outer side of each fixing block 6 has a sliding hole, through which a pedal 7 passes and slides. A push rod 8 is bolted to the lower part of the pedal 7, and the lower part of the push rod 8 has a wedge-shaped surface. A locking block 9 is fitted around the fixing blocks 6 and the push rod 8. The locking block 9 has a sliding groove 13 on the side facing the fixing block 6. A limit block is bolted to the inner side of the fixing block 6, and the locking block 9 slides with the limit block through the sliding groove 13. The lower front and rear sides of the fixing block 6 have locking grooves 14, allowing the lower part of the locking block 9 to slide. The push rod 8 is inserted into the locking groove 14 of the fixed block 6. Two vertically arranged limiting posts are respectively set at intervals on the front and rear sides of the push rod 8. The locking block 9 is located between the two limiting posts. In the fixed state, the locking block 9 is located in the locking groove 14 of the fixed block 6, and the connecting block 10 can rotate freely. When the push rod 8 moves down, the locking block 9 is pushed and slides into the locking groove 14 of the connecting block 10, thereby locking the connecting block 10. When the pedal 7 is stepped on, the push rod 8 moves downward accordingly. The upper limiting post on the push rod 8 first contacts the locking block 9 and applies a downward pushing force, forcing the locking block 9 to overcome the friction and move downward along the limiting block. Slide, causing its lower part to disengage from the locking groove of the fixed block 6; as the push rod 8 continues to descend, the locking block 9 moves further down and embeds into the locking groove 14 on the connecting block 10, thereby locking the connecting block 10 in its stable position after rotation. The lower outer side of the fixed block 6 is rotatably connected to the connecting block 10. The side of the connecting block 10 opposite to the push rod 8 is connected to the wedge block 11 by bolts. The wedge block 11 is adapted to the wedge surface of the push rod 8. The outer side of the connecting block 10 is equipped with a universal wheel 12. The front and rear sides of the connecting block 10 are provided with locking grooves 14 that cooperate with the locking block 9.

[0024] like Figure 1 , 6 and Figure 7As shown, it also includes a mounting plate 15, a sliding frame 16, a pull rod 17, a spring 18, a vertical plate 19, a screw 20, a knob 21, and a pressure block 22. The bottom of the processing table 5 is connected to the mounting plate 15 by bolts. The bottom of the processing table 5 and the mounting plate 15 are slidably connected by a sliding rod to the sliding frame 16. The front side of the sliding frame 16 is connected to the pull rod 17 by bolts. The rear end of the sliding frame 16 is connected to the front end of the mounting plate 15 by a spring 18. The left and right sides of the lifting plate 4 are connected to the vertical plate 19 by bolts. The top left and right sides of the vertical plate 19 are respectively threaded with two screws 20. The top of the screws 20 is connected to the knob 21 by bolts. The bottom of the screws 20 is connected to the pressure block 22 by bolts.

[0025] When processing door and window components, the bottom of bracket 1 directly contacts the ground, bearing the entire weight of the equipment and forming a stable support.

[0026] To adapt to the processing requirements of different workpieces, the operator can start the motor 2. The output shaft of the motor 2 drives the lead screw 3 to rotate. The lead screw 3 is threaded with the lifting plate 4, so that the lifting plate 4 can be raised and lowered smoothly along both sides of the bracket 1, thereby driving the processing table 5 to rise or fall as a whole. By adjusting the position of the lifting plate 4, the processing table 5 can be adjusted to the working height most suitable for the operator's height or process requirements, improving work comfort and processing accuracy.

[0027] During processing, the front and rear positions of the processing area can be adjusted according to the length of the door and window profiles. Pulling the pull rod 17 on the front side of the sliding frame 16 forward causes the sliding frame 16 to slide along the mounting plate 15, compressing the spring 18 at the rear end, thus extending and positioning the front of the processing table 5. After releasing the pull rod 17, the spring 18 returns to its original position, causing the sliding frame 16 to automatically return to its original position. The operation is simple and efficient. At the same time, by rotating the knob 21 on the top of the screw 20, the screw depth of the screw 20 on the vertical plate 19 can be adjusted, so that the pressure block 22 at the bottom of the screw 20 gradually presses the surface of the workpiece, achieving reliable clamping and preventing the workpiece from shifting during processing.

[0028] When the equipment needs to be moved to the next work position, the operator first slightly lifts the equipment and then presses down on the pedal 7. The pedal 7 drives the push rod 8 at its lower part to move down simultaneously. When the push rod 8 moves down, its lower wedge-shaped surface contacts the inclined surface of the wedge-shaped block 11 on the inner side of the connecting block 10. Under the action of the inclined surface, the connecting block 10 swings inward and downward around the pivot between it and the fixed block 6, driving the caster wheel 12 to gradually descend until it contacts the ground. As the push rod 8 continues to press down, the connecting block 10 drives the outer caster wheel 12 to gradually descend until all the caster wheels 12 are completely in contact with the ground. At this time, the bottom of the bracket 1 slowly lifts off the ground, and the entire weight of the equipment is transferred to the caster wheels 12. The platform enters a movable state and can be pushed to the target position.

[0029] As push rod 8 continues to move downward, wedge surface pushes wedge block 11, causing connecting block 10 to rotate outward and downward around the axis until its locking groove aligns with locking block 9. At this time, locking block 9 continues to move downward under the push of limit post, and finally embeds into locking groove 14 of connecting block 10, completing the locking.

[0030] This device enables rapid switching between fixed and mobile states through a simple stepping action. Its highly efficient, interconnected structure and intuitive operation make it easy to use. The coordinated functions of lifting adjustment, position sliding, and workpiece clamping comprehensively meet the combined needs of door and window processing sites for equipment stability, flexibility, and operational efficiency, demonstrating outstanding practical value.
