[0029] First embodiment

[0030] See also Figure 1-Figure 4 The utility model provides a technical solution: a ladder for safety engineering, comprising a ladder body 1 and an anti-skid mechanism, the anti-skid mechanism is arranged at the lower end of the ladder body 1, the anti-skid mechanism comprises a rotating plate 2 and anti-skid teeth 3, the rotating plate 2 is located at the front side of the ladder body 1, the rear end of the rotating plate 2 is hinged to the lower end of the ladder body 1, and the anti-skid teeth 3 are formed by protruding downward from the lower side of the rotating plate 2. In this embodiment, the anti-skid teeth 3 are four, it can be understood that the number of the anti-skid teeth 3 is not limited to four, for example, in some embodiments, the anti-skid teeth 3 can also be other numbers.

[0031] When the ladder for safety engineering described in the utility model is used on a muddy ground, the lower end of the ladder body 11 is supported on the muddy ground, and the upper end of the ladder body 1 is obliquely placed on the wall, so that the rotating plate 2 is located on the side of the ladder body 1 facing the wall. The rotating plate 2 is rotated, and the rotating plate 2 drives the anti-skid teeth 3 to move toward the muddy ground until the lower end of the anti-skid teeth 3 is supported on the muddy ground, and the upper side of the rotating plate 2 is pressed downward with the foot, so that the anti-skid teeth 3 arranged on the lower side of the rotating plate 2 are inserted into the mud. The anti-skid teeth 3 can be inserted and fixed in the mud more stably, so that the rotating plate 2 is not easy to slide on the muddy ground. Since the rear end of the rotating plate 2 is hinged to the lower end of the corresponding ladder body 1, the rotating plate 2 can pull and fix the lower end of the ladder body 1, which can reduce the possibility of the lower end of the ladder body 1 slipping, thereby reducing the occurrence of safety accidents.

[0032] After the use of the ladder for safety engineering described in the utility model is finished, the front end of the rotating plate 2 is pulled up and the front end of the rotating plate 2 is rotated upward, so that the anti-skid teeth 3 can be pulled out of the soil, and then the side of the rotating plate 2 facing away from the anti-skid teeth 3 is rotated to abut against the ladder body 1, that is, the rotating plate 2 can be folded onto the ladder body 1, and then the rotating plate 2 can be tied and fixed to the ladder body 1 with a rope, so that the side of the rotating plate 2 facing away from the anti-skid teeth 3 abuts against the ladder body 1. At this time, the rotating plate 2 can be in a folded and fixed state, which is more convenient when carrying the ladder for safety engineering described in the utility model.

[0033] In this embodiment, the ladder body 1 includes two vertical rods and a plurality of ladder rods, the two vertical rods are arranged in parallel with each other, the plurality of ladder rods are evenly spaced and arranged in the up-down direction, and the two ends of the ladder rods are respectively fixedly connected to the two vertical rods. In this embodiment, there are two anti-skid mechanisms, and the two anti-skid mechanisms are respectively arranged at the lower ends of the two vertical rods in a one-to-one correspondence. Specifically, for each anti-skid mechanism, the rear end of the rotating plate 2 is hinged to the lower end of a corresponding vertical rod. It can be understood that the anti-skid mechanism is not limited to two. For example, in some embodiments, the anti-skid mechanism can also be one, and one anti-skid mechanism is arranged on one of the vertical rods.

[0034] In this embodiment, two hinges are provided at the lower end of the ladder body 1. Specifically, the two hinges are provided at the lower ends of the two vertical rods in a one-to-one correspondence, one blade of the hinge is fixedly connected to the corresponding vertical rod, and the other blade is fixedly connected to the rear end of the corresponding rotating plate 2, so that the rotating plate 2 can rotate with the axis of the hinge as the rotating axis. With this structure, the rear end of the rotating plate 2 can be hinged to the lower end of the ladder body 1.

[0035] In this embodiment, the anti-slip mechanism further comprises a slider 4, a connecting rope 5 and a locking bolt 6. The front side of the ladder body 1 is recessed backward to form a slide groove 7. Specifically, the slide groove 7 is recessed backward from the front side of the vertical rod. The notch size of the slide groove 7 is smaller than the groove cavity size of the slide groove 7. Specifically, the cross section of the slide groove 7 is a "T" shape. In other embodiments, the cross section of the slide groove 7 can also be a dovetail shape with a larger back and a smaller front. The slider 4 is slidably fitted in the slide groove 7. One end of the connecting rope 5 is fixedly connected to the slider 4 and the other end is fixedly connected to the front end of the rotating plate 2. The front side of the slider 4 is recessed inward to form a locking screw hole 8. The locking bolt 6 is screwed into the locking screw hole 8. The bolt head of the locking bolt 6 is used to abut the front side of the ladder body 1. Specifically, the bolt head of the locking bolt 6 is used to abut the front side of the vertical rod.

[0036] See also Figure 5, rotate the locking bolt 6 so that the bolt head of the locking bolt 6 is separated from the front side of the ladder body 1, that is, the fixing of the locking bolt 6 to the slider 4 can be released, and the slider 4 can slide in the slide groove 7. Slide the slider 4 upward, and the slider 4 pulls one end of the connecting rope 5 to move upward, that is, the front end of the rotating plate 2 can be pulled by the other end of the connecting rope 5, so that the rotating plate 2 can rotate upward with the axis of the hinge as the rotating axis, and then the anti-slip teeth 3 can be pulled out of the soil. After continuing to slide the slider 4 for a certain distance, the front end of the rotating plate 2 rotates in the direction close to the ladder body 1, that is, the rotating plate 2 can be retracted on the ladder body 1. After the rotating plate 2 is folded onto the ladder body 1, the locking bolt 6 is rotated so that the bolt head of the locking bolt 6 is pressed against the front side of the ladder body 1 to lock the slider 4 onto the ladder body 1. That is, the rotating plate 2 can be fixed to the ladder body 1 by the connecting rope 5, which makes it more convenient to fold and fix the rotating plate 2 onto the ladder body 1.

[0037] When the ladder for safety engineering of the utility model needs to be used on the muddy ground, the locking bolt 6 is rotated to make the bolt head of the locking bolt 6 disengage from the front side of the ladder body 1, and the fixing of the locking bolt 6 to the slider 4 is released, so that the slider 4 can slide in the slide groove 7. The pulling force of the slider 4 on one end of the connecting rope 5 is released, and the rotating plate 2 can rotate. The rotating plate 2 is rotated, and the rotating plate 2 drives the anti-skid teeth 3 to move toward the muddy ground until the lower end of the anti-skid teeth 3 is supported on the muddy ground, and the upper side of the rotating plate 2 is pressed downward by the foot, so that the anti-skid teeth 3 arranged on the lower side of the rotating plate 2 are inserted into the mud.

[0038] Since the slot size of the slide slot 7 is smaller than the slot cavity size of the slide slot 7 , the possibility of the slider 4 being separated from the slide slot 7 can be reduced.

[0039] In this embodiment, the anti-slip mechanism further includes a fixed inserting portion 9, which is slidably arranged on the ladder body 1, and the lower end of the fixed inserting portion 9 is used to be inserted into the soil. With this structure, after the ladder body 1 is supported on the soil, the fixed inserting portion 9 is slid downward on the ladder body 1, and the fixed inserting portion 9 can be inserted into the soil. After the fixed inserting portion 9 is inserted into the soil, the lower end of the ladder body 1 can be fixed, which can further reduce the possibility of the lower end of the ladder body 1 slipping.

[0040] In this embodiment, please refer to Figure 5The lower side of the ladder body 1 is recessed upward to form a groove. Specifically, the lower side of the vertical rod is formed with a groove facing upward, and the upper end of the groove is connected to the groove cavity of the slide groove 7; the fixed plug part 9 includes a pin 901, and the pin 901 is slidably fitted in the groove cavity of the slide groove 7. The upper end of the pin 901 is fixedly connected to the lower side of the slider 4, and the lower end of the pin 901 is used to insert into the soil after passing through the groove downward.

[0041] The locking bolt 6 is rotated to make the bolt head of the locking bolt 6 separate from the front side of the ladder body 1, that is, the fixing of the locking bolt 6 to the slider 4 can be released, and the slider 4 can slide in the slide groove 7. The pin 901 is slid upward, and the pin 901 drives the slider 4 to slide upward until the pin 901 is completely pulled out of the mud and the lower end of the pin 901 is completely inserted into the groove, and the locking bolt 6 is rotated to make the bolt head of the locking bolt 6 close to the front side of the ladder body 1, and the slider 4 is locked to the ladder body 1, that is, the pin 901 that slides upward and is pulled out of the mud can be fixed to the ladder body 1, the pin 901 can be put into the groove and fixed to the ladder body 1, which is more convenient when moving the ladder for safety engineering described in the utility model.

[0042] During the process of sliding the slider 4 upward in the slide groove 7: the slider 4 pulls one end of the connecting rope 5 to move upward, that is, the front end of the rotating plate 2 can be pulled by the other end of the connecting rope 5, so that the rotating plate 2 can rotate upward with the axis of the hinge as the rotating axis, and then the anti-slip teeth 3 can be pulled out of the soil. After continuing to slide the slider 4 for a certain distance, the front end of the rotating plate 2 rotates in the direction close to the ladder body 1, that is, the rotating plate 2 can be retracted onto the ladder body 1.

[0043] The locking bolt 6 is rotated so that the bolt head of the locking bolt 6 is disengaged from the front side of the ladder body 1, and the fixing of the locking bolt 6 to the slider 4 can be released, and the slider 4 can slide in the slide groove 7. The pin 901 is slid downward, and the pin 901 drives the slider 4 to slide downward, and the lower end of the pin 901 passes through the groove and is inserted into the soil. The locking bolt 6 is rotated so that the bolt head of the locking bolt 6 is pressed against the front side of the ladder body 1, and the slider 4 is locked to the ladder body 1, and the pin 901 is fixed to the lower end of the ladder body 1. With this structure, the fixing part 9 can slide downward on the ladder body 1, and the lower end of the fixing part 9 can be inserted downward into the soil.

[0044] In this embodiment, the fixed insertion part 9 also includes a pedal 902, and the outer surface of the ladder body 1 is recessed inward to form a strip hole 10, and the strip hole 10 is connected to the groove cavity of the slide groove 7. One end of the pedal 902 is fixedly connected to the upper end of the pin 901, and the other end passes through the strip hole 10 and protrudes from the outer surface of the ladder body 1.

[0045] The upper side of the pedal 902 is pressed with the foot to move the pedal 902 downward, and the pedal 902 drives the pin 901 to slide downward, so that the lower end of the pin 901 can be inserted into the soil. With this structure, it is more convenient to insert the lower end of the pin 901 into the soil.

[0046] When the pedal 902 is moved upward: the staff lifts the pedal 902 upward, and the pedal 902 moving upward can drive the pin 901 to slide upward, that is, the lower end of the pin 901 can be pulled out of the soil. With this structure, it is more convenient to pull the lower end of the pin 901 out of the soil.

[0047] In this embodiment, the fixed inserting portion 9 further includes a collar 903 , and the collar 903 is fixedly connected to the upper side of the pedal 902 , and the inner cavity of the collar 903 is used to accommodate the feet of the staff.

[0048] The worker inserts his foot into the ring 903, and the ring 903 restricts the worker's foot on the pedal 902. When the pedal 902 is pressed to insert the lower end of the pin 901 into the soil, the possibility of the worker's foot slipping off the pedal 902 is reduced. When the lower end of the pin 901 is pulled out of the soil, the worker only needs to lift his foot, and the ring 903 and the pedal 902 can drive the pin 901 to move upward. In this process, the worker does not need to bend over, which makes it more convenient to pull the lower end of the pin 901 out of the soil.

[0049] In this embodiment, in the ladder for safety engineering described in the utility model, the bottom ends of the anti-slip teeth 3 are all inclined backwards.

[0050] When a worker climbs on the ladder for safety engineering of the utility model, the sliding direction of the lower end of the ladder body 1 is toward the rear of the ladder body 1. When the lower end of the ladder body 1 slides backward, the lower end of the ladder body 1 exerts a backward pulling force on the rotating plate 2. Since the bottom end of the anti-slip teeth 3 is tilted backward, after the anti-slip teeth 3 are inserted into the soil, when the ladder body 1 exerts a backward pulling force on the rotating plate 2, the anti-slip teeth 3 can grip the soil more firmly.

[0051] Second embodiment

[0052] See also Figure 6 and Figure 7 The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0053] The difference between this embodiment and the first embodiment is that the connection structure between the slider 4 and the rotating plate 2 in the anti-slip mechanism is different, and the rest of the parts are the same as those in the first embodiment.

[0054] Specifically, the anti-slip mechanism also includes a slider 4, a connecting rod 11 and a locking bolt 6. The front side surface of the ladder body 1 is recessed backward to form a slide groove 7. The notch size of the slide groove 7 is smaller than the groove cavity size of the slide groove 7. The slider 4 slides in the slide groove 7. One end of the connecting rod 11 is hinged to the slider 4 and the other end is hinged to the rotating plate 2. The front side surface of the slider 4 is recessed inward to form a locking screw hole 8. The locking bolt 6 is screwed into the locking screw hole 8. The bolt head of the locking bolt 6 is used to resist the front side surface of the ladder body 1.

[0055] The locking bolt 6 is rotated so that the bolt head of the locking bolt 6 is separated from the front side of the ladder body 1, that is, the fixing of the locking bolt 6 to the slider 4 can be released, and the slider 4 can slide in the slide groove 7. When the pin 901 is slid upward, the pin 901 drives the slider 4 to slide upward, and the slider 4 sliding upward pulls the front end of the rotating plate 2 to rotate through the connecting rod 11, so that the rotating plate 2 rotates upward with the axis of the hinge as the rotating axis. Until the lower end of the pin 901 is completely pulled out of the soil and the lower end of the pin 901 is completely inserted into the groove, and until the side of the rotating plate 2 facing away from the anti-slip teeth 3 is rotated to abut against the ladder body 1, the locking bolt 6 is rotated so that the bolt head of the locking bolt 6 abuts against the front side of the ladder body 1 to lock the slider 4 on the ladder body 1. At this time, the pin 901 can be in a state of being received in the groove and fixed on the ladder body 1, and the rotating plate 2 can be in a state of being retracted and fixed. While the pin 901 is received in the groove and fixed on the ladder body 1, the rotating plate 2 can also be retracted and fixed on the ladder body 1, making the ladder for safety engineering described in the utility model more convenient to use.

[0056] The locking bolt 6 is rotated so that the bolt head of the locking bolt 6 is separated from the front side of the ladder body 1, that is, the fixing of the locking bolt 6 to the slider 4 can be released, and the slider 4 can slide in the slide groove 7. When the pin 901 slides downward, the pin 901 drives the slider 4 to slide downward, and the slider 4 sliding downward pushes the front end of the rotating plate 2 to rotate through the connecting rod 11, so that the rotating plate 2 rotates downward with the axis of the hinge as the rotating axis. After the connecting rod 11 pushes the rotating plate 2 to rotate, the anti-slip teeth 3 are completely inserted into the soil, and the pin 901 can be stopped from sliding downward. At this time, the lower end of the pin 901 passes through the groove and is inserted into the soil. The locking bolt 6 is rotated so that the bolt head of the locking bolt 6 is pressed against the front side of the ladder body 1, and the slider 4 is locked on the ladder body 1, that is, the pin 901 can be fixed to the lower end of the ladder body 1. The connecting rod 11 can also be fixed to the ladder body 1, and the connecting rod 11 can abut against the upper side of the rotating plate 2, so that the rotating plate 2 can be stably connected to the ladder body 1, reducing the possibility of rotation of the rotating plate 2, so that the anti-slip teeth 3 can be more stably inserted and fixed in the soil, making it less likely for the rotating plate 2 to slide on the muddy ground. Since the rear end of the rotating plate 2 is hinged to the lower end of the corresponding ladder body 1, the rotating plate 2 can pull and fix the lower end of the ladder body 1, which can further reduce the possibility of slipping of the lower end of the ladder body 1.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
