Description

Technical Field

[0001] The invention relates to the technical field of climbing equipment, in particular to a lightweight gecko ladder for mountain tree climbing. Background Art

[0002] With the large-scale planting of fruit trees in the forest and the rise of outdoor sports, activities such as fruit picking, field rescue and field operations are becoming more and more common in complex mountain environments. During emergency rescue, outdoor adventures and fruit picking, operators must set up ladders in a short time due to time limits and work intensity, and the stability of the ladders must be maintained during the operation to ensure the safety of the operators.

[0003] At present, although traditional climbing equipment, such as metal ladders and ropes, can meet the climbing conditions in some environments, they are often bulky and difficult to carry when facing complex mountain terrain and working on lush trees. The working terrain is complex, it is difficult to carry out work, and the space is small and inconvenient to operate. Therefore, the working ladder carried by the operator must have the characteristics of safety, lightness, and strong adaptability to the working terrain. For this reason, the present invention proposes a lightweight gecko ladder for mountain tree climbing. Summary of the invention

[0004] The purpose of the present invention is to provide a lightweight gecko ladder for mountain tree climbing in response to the technical problems existing in the existing ladders in actual work. The ladder is light in weight, small in size, and detachable, so it is easy to carry up the mountain. In actual work, the ladder is stable and highly safe. The length of the ladder can be changed according to the specific conditions of the tree species being operated, and it can adapt to operations on various terrains.

[0005] In order to solve the above problems, the technical solution adopted by the present invention is:

[0006] The present invention provides a light-weight gecko ladder for mountain tree climbing, comprising a detachable main ladder, a V-shaped tree clamp and a foot fork;

[0007] The detachable main ladder is used by operators to climb trees in mountainous areas for operations.

[0008] The main material of the detachable main ladder is a hollow aluminum-magnesium alloy square tube;

[0009] Furthermore, the detachable main ladder is divided into a first main ladder and a second main ladder, both sides of the first main ladder and the second main ladder are connected with foldable non-slip foot pedals, and the two parts are connected by a cylindrical pin, so that a single main ladder or a double main ladder can be used for climbing trees of different heights, and the required functions can be achieved by disassembling the cylindrical pins;

[0010] Specifically, the foldable foot pedal can be folded when placed and transported and opened when working, and the maximum rotation angle of the pedal is 90°.

[0011] The tree clamping mechanism of the V-shaped tree clamp is composed of two supports in a V-shaped structure. Anti-skid rubber pads are pasted inside the supports to fix the ladder. During actual operation, the tree trunk is placed in the two supports on the V-shaped tree clamp to improve the stability of the operation.

[0012] The foot fork is used to fix the ladder. During actual operation, the two sharp heads of the foot fork are inserted into the ground to fix the two together, thereby improving the stability of the operation.

[0013] Furthermore, the foot fork is provided with an anti-slip rubber sleeve. When working in the mountains, the rubber sleeve is separated from the head of the foot fork, and the foot fork is inserted into the ground for working; when working on muddy ground, the rubber sleeve is put on the head of the foot fork to increase the contact area and friction between the foot fork and the ground.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The present invention is lightweight and portable. The main ladder is made of a hollow aluminum-magnesium alloy square tube, which reduces the weight of the ladder while ensuring its strength. The foot pedals on the main ladder are foldable. When transporting the ladder, the foot pedals are in a folded state, saving space and being easy to carry. When using the ladder, the foot pedals are opened for work.

[0016] (2) When the present invention is applied to actual work, the operator's working posture is similar to that of a gecko crawling. The structure of the foot pedals on the main ladder is an asymmetric equidistant progressive type, which reduces the number of foot pedals and reduces the weight of the ladder. When climbing, the operator imitates the movement posture of a gecko, which reduces the space occupied by the foot pedals, increases the operator's movement space, and improves the climbing speed.

[0017] (3) The present invention is mainly suitable for mountain tree climbing operations. During operation, the ladder is tilted at a small angle, the sharp head of the fork is inserted into the ground, and the tree trunk is placed in the two supports on the V-shaped tree support clamp. The anti-skid rubber pad inside the support can increase the friction between the ladder and the tree trunk, while improving the stability of the operation, reducing the damage of the ladder to the tree trunk epidermis, so that the ladder, the tree and the ground are tightly fixed, improving the stability of the operation and the safety of the operator. The present invention can also be used on muddy ground. When used on muddy ground, the anti-skid rubber sleeve carried on the fork can be put on the fork to increase the contact area and friction between the fork and the ground, so as to realize the multi-scenario application of the present invention. When transporting the ladder, the anti-skid rubber sleeve can also be put on the fork to avoid accidental injury to the operator by the sharp head of the fork. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings.
