Description

Technical Field

[0001] This utility model specifically relates to a tree pruning ladder with a safety protection structure, belonging to the field of greening technology. Background Technology

[0002] Urban landscaping management refers to the construction, maintenance, and management of various green spaces, woodlands, parks, scenic areas, and nurseries within a city, undertaken by the city's administrative departments with the cooperation of other departments and social participation. This involves creating beautiful natural environments and recreational areas through methods such as terrain modification, planting trees and flowers, constructing buildings, and arranging garden paths. Urban greening construction has steadily developed alongside the continuous increase in urbanization rates. In urban greening, it is often necessary to prune the lateral branches of newly planted saplings. Traditionally, pruning lateral branches of saplings is done with shears; for some taller lateral branches that require pruning, ladders are needed.

[0003] However, the existing technology still has the following shortcomings in use: construction workers are at risk of slipping when climbing ladders, which may lead to falls from heights and threaten the personal safety of the workers, resulting in poor safety. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a tree pruning ladder with a safety protection structure, thereby achieving high sensitivity and better information collection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tree pruning ladder with a safety protection structure, comprising a ladder frame, a pair of handrails fixedly connected to the ladder frame, a sleeve slidably connected to one of the handrails, and a ratchet rack fixedly connected thereto, a mounting plate fixedly connected to the sleeve, a limit block rotatably connected to the mounting plate, a pair of limit grooves provided on the limit block, the limit block engaging with the ratchet rack through the limit grooves, an elastic component for pushing the limit block to reset connected to the mounting plate, a construction platform fixedly connected above the ladder frame, a barrier component fixedly connected above the construction platform, and a retaining ring fixedly connected to the sleeve.

[0006] Furthermore, the elastic component includes a fixing block fixedly connected to the mounting plate, a first spring fixedly connected to the fixing block, and the end of the first spring away from the fixing block is also fixedly connected to a limiting block.

[0007] Furthermore, a positioning shaft is fixedly connected to the limiting block.

[0008] Furthermore, the enclosure component includes a guardrail fixedly connected to the top of the construction platform, and both sides of the guardrail are slidably connected to a shielding door.

[0009] Furthermore, a pair of second springs are fixedly connected to the shielding door, and the end of the second spring away from the shielding door is also fixedly connected to the guardrail.

[0010] Furthermore, the ladder frame is fixedly connected with multiple evenly distributed footboards.

[0011] Beneficial effects:

[0012] This tree pruning ladder with a safety protection structure allows the sleeve to move automatically upwards but not downwards through the interlocking action of the lower limit groove on the limiting block and the ratchet. This improves the safety of construction workers during operation, makes it more convenient to use, and enhances the protection of construction workers. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5As shown, a tree pruning ladder with a safety protection structure includes a ladder frame 100. A pair of handrails 101 are fixedly connected to the ladder frame 100. A sleeve 102 is slidably connected to one of the handrails 101, and a ratchet rack 105 is also fixedly connected thereto. A mounting plate 103 is fixedly connected to the sleeve 102. A limit block 104 is rotatably connected to the mounting plate 103. A pair of limit grooves 106 are provided on the limit block 104. The limit block 104 cooperates with the ratchet rack 105 through the limit grooves 106. A device for pushing the limit block 105 is connected to the mounting plate 103. 04. The elastic component for resetting: A construction platform 107 is fixedly connected above the ladder frame 100, and a fence component is fixedly connected above the construction platform 107. A retaining ring 108 is fixedly connected to the sleeve 102. Under the action of the limiting groove 106 on the limiting block 104 engaging with the ratchet 105, the sleeve 102 can only move upward along the handrail 101. After the construction personnel connect to the sleeve 102 through the retaining ring 108, a fall prevention mechanism can be realized during the construction personnel's upward climbing process, which is conducive to improving the safety of construction personnel during operation.

[0021] Please see Figure 1-4 As shown, a tree pruning ladder with a safety protection structure includes an elastic component comprising a fixing block 110 fixedly connected to a mounting plate 103, a first spring 111 fixedly connected to the fixing block 110, and the end of the first spring 111 away from the fixing block 110 being fixedly connected to a limiting block 104. The limiting block 104 is deflected by the first spring 111, which helps to improve the performance.

[0022] Please see Figure 1-3 As shown, a tree pruning ladder with a safety protection structure has a positioning shaft 112 fixedly connected to a limiting block 104. When the construction worker descends, the positioning shaft 112 can be continuously pushed upward to drive the limiting block 104 to deflect, thereby releasing the limiting function of the limiting block 104 and improving the convenience of adjusting the angle of the limiting block 104.

[0023] Please see Figure 1-3 As shown, a tree pruning ladder with a safety protection structure and a fencing component are also provided. Figure 1-5 As shown, a tree pruning ladder with a safety protection structure has a pair of second springs 122 fixedly connected to the blocking door 121. The end of the second spring 122 away from the blocking door 121 is also fixedly connected to the guardrail 120. Under the action of the second spring 122, the blocking door 121 can be pushed to reset. A gap is provided between the two blocking doors 121 to allow passage for the safety belt, making it more convenient to use.

[0024] Please see Figure 1-2As shown, a tree pruning ladder with a safety protection structure is provided. The ladder frame 100 is fixedly connected with multiple evenly distributed steps 123, and the bottom of the ladder frame 100 is also provided with self-locking casters, which can realize the convenience of moving the ladder frame 100. The multiple steps 123 make it easier for construction workers to climb and improve work efficiency.

[0025] Specifically, when using this device: First, move the ladder frame 100 to the desired position using the self-locking casters. When performing high-altitude work, workers must wear a safety harness with a limited length and securely connect the other end of the harness to the retaining ring 108 on the sleeve 102 using a buckle. During climbing, the safety harness pulls the sleeve 102 along the handrail 101 as the worker ascends. As the sleeve 102 moves upward, the limiting block 104 automatically deflects under the engagement of the limiting groove 106 and the precision ratchet 105. The first spring 111 pushes the limiting block 104 back to its original position and engages with the ratchet 105, forming a progressive fall prevention mechanism. If a fall occurs, the first spring 111 pushes the limiting groove 106 on the limiting block 104 to engage with the ratchet 105. 05. The tight engagement of the ratchet 105 and the limiting groove 106 ensures that the sleeve 102 can only slide upwards and not downwards. The linkage between the sleeve 102 and the safety belt provides rapid braking, effectively preventing personnel from falling. Upon reaching the construction platform 107, the construction personnel can simply push the two side shielding doors 121 to enter. After releasing, the second spring 122 automatically resets and closes the shielding doors 121. The gap between the two shielding doors 121 provides passage space for the safety belt. When descending after the work is completed, the positioning shaft 112 is pushed to release the engagement between the limiting block 104 and the ratchet 105, thereby adjusting the position of the sleeve 102. This achieves a perfect combination of protective function and operational convenience, which helps improve the safety of construction personnel during work.
