Description

Technical Field

[0001] The utility model relates to the technical field of vehicle boarding ladders, in particular to a vehicle boarding ladder which is convenient to carry. Background Art

[0002] During the maintenance and disassembly process of a certain type of vehicle armored equipment, maintenance personnel need to frequently get on and off the vehicle body. Since the armored vehicle body is relatively high, it is inconvenient for maintenance personnel to get on and off the vehicle body. Other existing ladders do not match the height, making it inconvenient and unsafe to get on and off the vehicle body. In addition, the existing step ladders are large in size and are not convenient to carry when working in the field. Therefore, we have introduced a convenient and portable boarding ladder.

[0003] The existing vehicle ladder is large in size and inconvenient to carry to field operations. In addition, when workers use the vehicle ladder to repair the vehicle, they often need to carry a large number of tools. These tools have nowhere to be placed. Once they fall, they are easy to accidentally injure people below and need to be picked up again, which is very inconvenient to use. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a conveniently portable boarding ladder, comprising a base 1, a movable caster 2 is provided at the bottom of the base 1, a lifting assembly 3 is provided at the top of the base 1, the top of the lifting assembly 3 is slidably connected to the bottom of the boarding ladder body 4, a storage basket 5 is fixedly connected to one side of the top of the boarding ladder body 4 by bolts, two plug-in tubes 6 are fixedly connected to the top of the boarding ladder body 4, two groups of bearing members 7 are fixedly connected to one side of the boarding ladder body 4 provided with a step, and the insides of the two plug-in tubes 6 are both plugged with The escalator 8; the supporting member 7 is a semi-sectioned tubular structure, and the supporting member 7 is perpendicular to the inclined surface of the boarding ladder body 4. The supporting member 7 can support the escalator 8, and the escalator 8 can be installed on the boarding ladder body 4 in conjunction with the plug-in tube 6 on the top. After the boarding ladder is used, the escalator 8 can be pulled upwards and removed from the boarding ladder body 4, thereby reducing the size of the boarding ladder, making it easy to carry and suitable for field operations. The storage basket 5 can be used to store tools to prevent too many tools from falling and injuring people during operations.

[0023] In this embodiment, Figure 4 and Figure 5As shown, the mobile caster 2 includes a mounting plate 201 fixedly connected to the corner of the bottom surface of the base 1, and the mounting plates 201 are arranged in groups of two, with a total of four groups, and each group of mounting plates 201 is rotatably connected with a connecting shaft 202 and a caster body 203, the connecting shaft 202 is located above the caster body 203, and a torsion spring 204 is fixedly connected between the two ends of the connecting shaft 202 and the mounting plate 201, and a pedal 205 is fixedly connected to one side of the middle part of the connecting shaft 202, and the pedal 205 extends to the outer side of the edge of the base 1, and the pedal 205 is Two locking blocks 206 are fixedly connected on both sides of the middle part, and a mounting hole 207 is opened in the middle part of the side where the two locking blocks 206 are close to each other. A spring 208 is fixedly connected inside the mounting hole 207, and a locking pin 209 is fixedly connected to one end of the spring 208 close to the outer side of the mounting hole 207. A plurality of locking holes 2010 are opened on the surface of the caster body 203, and the plurality of locking holes 2010 are equiangularly distributed on the edge of the caster body 203; the boarding ladder can be driven to move by the caster body 203, and when the boarding ladder moves to After the designated position is reached, the pedal 205 is stepped on downward to drive the two locking blocks 206 to rotate around the connecting shaft 202. At this time, the connecting shaft 202 will drive the torsion spring 204 to deform. The rotation of the locking block 206 will drive the inner locking pin 209 to rotate together and make the locking pin 209 contact with the caster body 203. When the caster body 203 contacts the locking pin 209, the locking pin 209 will be squeezed into the mounting hole 207. At this time, the locking pin 209 will compress the spring 208. When the locking pin 209 is in the locking hole 207, the locking pin 208 will be pressed into the mounting hole 207. When the axes 10 coincide, the spring 208 rebounds, driving the locking pin 209 to be inserted into the locking hole 2010, thereby fixing the caster body 203 to prevent the boarding ladder from moving. When the lock needs to be released, the pedal 205 is moved upward. At this time, the locking pin 209 will be squeezed into the mounting hole 207 again, and then, under the action of the torsion spring 204, the pedal 205 and the locking block 206 will be reset through the connecting shaft 202. At this time, the locking pin 209 is disengaged from the caster body 203, and the boarding ladder can be moved again.

[0024] In this embodiment, Figure 2 and Figure 3As shown, the lifting assembly 3 includes a motor 301 fixedly connected to one side of the base 1, the output end of the motor 301 is fixedly connected to a threaded rod 302, the middle part of the threaded rod 302 is threadedly connected to a moving bar 303, the end of the threaded rod 302 away from the motor 301 is rotatably connected to one side of a fixed bar 307, the top ends of the moving bar 303 are respectively hinged with two push rods 304, the top ends of the two push rods 304 are fixedly connected with sliders 305, the sliders 305 are divided into a moving block and a fixed block, the moving block is located in the slide groove at the bottom of the boarding ladder body 4, and the fixed block is welded to the bottom surface of the boarding ladder body 4, the bottom slide groove of the boarding ladder body 4 is "T" shaped, the top ends of the fixed bar 307 are hinged with two push rods 304, and the fixed bar 30 The push rods 304 hinged on the top surface of 7 and the push rods 304 hinged on the top surface of the moving bar 303 are cross-distributed, and a rotating shaft 306 runs through the middle of the two groups of push rods 304, and the rotating shaft 306 and the push rods 304 are rotatably connected; when it is necessary to adjust the height of the boarding ladder, the motor 301 drives the threaded rod 302 to rotate, and the rotation of the threaded rod 302 can drive the moving bar 303 to move in the direction of the fixed bar 307. At this time, the push rod 304 will rotate around the rotating shaft 306. At this time, the push rod 304 drives the moving block in the slider 305 to slide along the slide groove on the bottom surface of the boarding ladder body 4, and the fixed block in the slider 305 remains stationary. The push rods 304 approach each other to lift the boarding ladder body 4, thereby realizing the height adjustment of the boarding ladder.

[0025] The use method and advantages of the utility model: When the portable boarding ladder is used, the working process is as follows:

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, firstly, the base 1 and the boarding ladder body 4 are driven to move by moving the casters 2, which facilitates the movement of the boarding ladder and does not require manual handling. When the boarding ladder reaches the specified position, the pedal 205 and the locking pin 209 at the bottom are used to lock the caster body 203 to prevent the caster body 203 from moving during operation. If it is necessary to adjust the height of the boarding ladder, the motor 301 drives the threaded rod 302 to rotate, and the threaded rod 302 drives the moving bar 303 to move toward the fixed bar, thereby driving the cross-distributed push rods 304 on the top to push the boarding ladder body 4 upward to achieve the height adjustment of the boarding ladder. When it is necessary to carry the boarding ladder out, the escalator 8 is pulled upward to disengage the escalator 8 from the plug-in tube 6 and the bearing member 7, and can be removed from the boarding ladder body 4, so that the boarding ladder is reduced in size, easy to carry, and suitable for field operations. The storage basket 5 can be used to store tools to prevent too many tools from falling and injuring people when working.
