Description

Technical Field

[0001] This utility model belongs to the field of slope construction technology, specifically relating to a safety ladder for slope construction. Background Technology

[0002] Slopes are typically located in mountainous areas, along rivers, or along highways. The terrain is steep and irregular, and the construction environment is complex. Slopes may consist of rock, loose soil, or weathered layers, and have poor geological stability, making them prone to landslides or collapses. Therefore, safety ladders are usually required when constructing slopes to provide workers with a safe and efficient vertical passage.

[0003] Traditional safety ladders for slope protection typically use simple steel ladders erected manually. These ladders are time-consuming to set up and can only be fixed in one location. When the ladder's position needs to be changed, the overall tilt angle may change after the entire ladder is moved, but the steps remain fixed. This can cause the steps to tilt, endangering the safety of workers. Re-erecting the ladder is also time-consuming and labor-intensive. Summary of the Invention

[0004] To overcome the problem in the prior art that the angle of the ladder steps cannot be changed, which requires rebuilding the ladder after the ladder is moved, resulting in time and labor costs, this utility model provides a safety ladder for slope construction. It can adjust the angle of the steps to make it suitable for more slope construction scenarios, is easy to assemble and disassemble, and improves construction efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A safety ladder for slope construction includes a support pipe 1, a column 2, a footboard 3, a connecting cylinder 4, a screw 5, an open clamping sleeve 6, and a connecting mechanism 7.

[0007] The support tube 1 consists of two parallel tubes. Each end of the support tube 1 is hinged to a column 2. A pedal 3 is installed between the two support tubes 1. The rear end of the pedal 3 is hinged to the support tube 1 via a connecting mechanism 7. Connecting cylinders 4 are provided on both sides below the front end of the pedal 3. A screw 5 is threaded into the connecting cylinder 4. The lower end of the screw 5 is connected to an open sleeve 6 via a ball joint. The open sleeve 6 is engaged with the support tube 1.

[0008] Furthermore, the connecting mechanism 7 includes a buckle 71 and a connecting rod 72;

[0009] The two ends of the connecting rod 72 are respectively fixedly installed with buckles 71, and the pedal 3 is provided with mounting holes, through which the connecting rod 72 passes.

[0010] Furthermore, the buckle 71 includes two semi-circular connecting sleeves, one end of which is hinged together and the other end is fixed by bolts;

[0011] One of the connecting sleeves is fixedly connected to the connecting rod 72.

[0012] Furthermore, it also includes a support plate 8, which has connection holes;

[0013] The column 2 is driven into the ground after passing through the connecting hole.

[0014] Furthermore, horizontal bars 9 are evenly spaced upward parallel to the support tube 1, and the two ends of the horizontal bars 9 are respectively hinged to the corresponding columns 2.

[0015] Furthermore, the pedal 3 is provided with anti-slip grooves.

[0016] The beneficial effects of this utility model are:

[0017] The rear end of the pedal of this utility model is hinged to the support tube through a connecting mechanism. By rotating the screw, the length of the screw extending from the connecting cylinder can be adjusted, thereby adjusting the height of the front end of the pedal on the support tube. This makes the angle of the pedal adjustable, so that the pedal remains horizontal during installation, improving the safety of the device. It solves the problem that the angle of the traditional climbing ladder cannot be changed, which requires rebuilding the climbing ladder after changing its position, which is time-consuming and laborious.

[0018] This utility model also has the following beneficial effects:

[0019] The lower end of the column of this utility model is provided with a support plate to prevent local settlement caused by soft soil, which would lead to instability of the column and thus affect the safety and stability of the ladder.

[0020] When setting up a ladder, simply fasten the buckle in the connecting mechanism at the rear of the step onto the support tube, and then press down the open sleeve at the front of the step onto the steel pipe to achieve quick installation of the step. This is convenient, fast, time-saving, and labor-saving, improving the efficiency of ladder setup. Attached Figure Description

[0025] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0026] This utility model discloses a safety ladder for slope construction, such as Figure 1-2 As shown, it mainly includes a support tube 1, a column 2, a pedal 3, a connecting cylinder 4, a screw 5, an open ferrule 6, and a connecting mechanism 7.

[0027] The support tube 1 consists of two parallel tubes. Each end of the support tube 1 is hinged to a column 2. A pedal 3 is installed between the two support tubes 1. The rear end of the pedal 3 is hinged to the support tube 1 via a connecting mechanism 7. Connecting cylinders 4 are provided on both sides below the front end of the pedal 3. A screw 5 is threaded into the connecting cylinder 4. The lower end of the screw 5 is connected to an open sleeve 6 via a ball joint. The open sleeve 6 is engaged with the support tube 1.

[0028] In use, first assemble the ladder and then install it on the slope. During assembly, first place the two support pipes 1 parallel to each other, then install the rear end of the pedal 3 between the two support pipes 1 through the connecting mechanism 7. The front end of the pedal 3 is secured to the support pipe 1 by pressing down on the open sleeves 6 on both sides of the front end of the pedal 3. Install several pedals 3 evenly spaced between the two support pipes 1 in the same way to achieve quick installation of the pedals 3. After installing the pedals 3, lift the two support pipes 1 with the pedals 3 installed and place them on the slope. Adjust the pedals 3 at the end of the ladder by rotating the screws 5 on both sides below the front end of the pedal 3. Move the screw 5 up and down from the connecting cylinder 4 to a suitable length, thereby adjusting the height of the front end of the pedal 3 and adjusting the levelness of the pedal 3 on the slope, ensuring it remains level on the inclined slope. Then, lift the two support pipes 1 with the pedals 3 installed and place them on a horizontal surface. Adjust the angle of the remaining pedals 3 according to the pedals 3 at the ends, thereby adjusting all the pedals 3. After the pedals 3 are adjusted, install the columns 2 on both ends of the support pipes 1 respectively, and the entire device is assembled. Move the assembled ladder to the slope and fix the columns 2 at both ends of the ladder to the upper and lower ends of the slope respectively, thus completing the installation of the device.

[0029] When changing the location of the ladder, remove the two support pipes 1 from the uprights 2 and place them at the desired location. Adjust the angle of the pedals 3 at the ends of the support pipes 1 according to the angle of the new location, ensuring the pedals 3 are level again on the inclined slope. Then, place the two support pipes 1 with the pedals 3 installed on them on a horizontal surface and adjust the angles of all the pedals 3 according to their end angles. After adjusting the pedal angles, install the uprights 2 at both ends of the two support pipes 1. Move the entire ladder and nail the uprights 2 at both ends of the ladder into the upper and lower ends of the slope, completing the movement of the entire device. The pedals 3 can be adjusted without disassembling them again, ensuring they remain level after the move. This solves the problem of traditional ladders having fixed pedal angles, which necessitates rebuilding the ladder after a change of location, resulting in wasted time and effort.

[0030] The screw 5 at the front end of the pedal 3 is connected to the open sleeve 6 via a ball joint. The ball joint allows the screw 5 to rotate after the open sleeve 6 is installed on the support tube 1, thereby adjusting the height of the front end of the pedal 3. The open sleeve 6 is annular with a notch smaller than the diameter of the support tube. This allows the open sleeve 6 to be pressed down and locked onto the support tube 1 during installation, enabling quick installation of the pedal 3. At the same time, once the open sleeve 6 is locked, it is not easy to fall off the support tube. Therefore, if a worker accidentally kicks the bottom front end of the pedal 3 while walking on the ladder, the pedal 3 will not tilt upwards, effectively improving the safety of the ladder.

[0031] In some specific embodiments, a fixing nut is threaded onto the fixing screw 5. After adjusting the position of the pedal 3 (i.e. the extension length of the fixing screw 5), the fixing nut is rotated so that it fits tightly against the lower end face of the connecting cylinder 4 and locks in place, thereby locking the extension distance of the fixing screw 5. In this way, the pedal can be effectively prevented from tilting due to the rotation of the fixing screw 5 when the pedal 3 is repeatedly stepped on, further improving the safety of the ladder.

[0032] In some specific embodiments, the connecting mechanism 7 includes a buckle 71 and a connecting rod 72;

[0033] The two ends of the connecting rod 72 are respectively fixedly installed with buckles 71, and the pedal 3 is provided with mounting holes, through which the connecting rod 72 passes.

[0034] The connecting rod 72 passes through the mounting hole at the rear end of the pedal 3, allowing the pedal 3 to be rotatably connected to the connecting rod 72. The buckles 71 at both ends of the connecting rod 72 are fixedly installed on the support tube 1, so that it can cooperate with the screw 5 at the front end of the pedal 3 to adjust the level of the pedal 3. It is easy to install, saving time and effort.

[0035] In some specific embodiments, the buckle 71 includes two semi-circular connecting sleeves, one end of the two connecting sleeves is hinged together, and the other end is fixed by bolts;

[0036] One of the connecting sleeves is fixedly connected to the connecting rod 72.

[0037] When in use, unscrew the bolts on the buckle 71, clamp the two connecting sleeves on the buckle 71 onto the support tube 1, and then tighten the bolts to fix it. This allows it to be installed on the support tube 1 without having to be fitted from the end of the support tube 1, making the installation and disassembly of the device more convenient and quick.

[0038] In some specific embodiments, a support plate 8 is also included, wherein the support plate 8 is provided with connecting holes;

[0039] The column 2 is driven into the ground after passing through the connecting hole.

[0040] After the column is nailed into the ground, the support plate 8 is attached to the ground to prevent local settlement caused by soft soil, which could lead to instability of the column and affect the safety and stability of the ladder.

[0041] In some specific embodiments, horizontal bars 9 are evenly spaced and arranged parallel to the support tube 1, and the two ends of the horizontal bars 9 are respectively hinged to the corresponding columns 2.

[0042] When workers are climbing up or down the ladder or transporting materials, they can move by holding onto the horizontal bar 9, which increases the safety of the device. The two ends of the horizontal bar 9 are respectively installed on the column 2, which increases the stability of the device.

[0043] In some specific embodiments, the step 3 is provided with anti-slip grooves. This increases the friction between the worker's shoe sole and the step 3, achieving an anti-slip effect and increasing the safety of climbing the ladder.

[0044] Work process:

[0045] In use, first assemble the ladder and then install it on the slope. During assembly, first place the two support pipes 1 parallel to each other, then install the rear end of the pedal 3 between the two support pipes 1 through the connecting mechanism 7. The front end of the pedal 3 is secured to the support pipe 1 by pressing down on the open sleeves 6 on both sides of the front end of the pedal 3. Install several pedals 3 evenly spaced between the two support pipes 1 in the same way to achieve quick installation of the pedals 3. After installing the pedals 3, lift the two support pipes 1 with the pedals 3 installed and place them on the slope. Adjust the pedals 3 at the end of the ladder by rotating the screws 5 on both sides below the front end of the pedal 3, causing the screws 5 to move up and down from inside the connecting cylinder 4. When it reaches... When the appropriate length is reached, tighten the fixing nut on the screw 5 upwards to fix the length of the screw 5 extending into the connecting cylinder 4. Then adjust the height of the front end of the pedal 3 to adjust the levelness of the pedal 3 on the slope, keeping it level on the inclined slope. Then lift the two support tubes 1 with the pedal 3 installed and place them on the horizontal surface. Adjust the angle of the remaining pedals 3 according to the pedals 3 at the ends, thereby adjusting all the pedals 3. After the pedals 3 are adjusted, install the columns 2 on both ends of the support tubes 1 respectively. The entire device is now assembled. Move the assembled ladder to the slope and fix the columns 2 at both ends of the ladder to the upper and lower ends of the slope respectively. The installation of the device is now complete.
