Description

Technical Field

[0001] The invention belongs to the technical field of protective equipment, in particular to a stair operation baffle. Background Art

[0002] Inside a power plant, due to the compact layout, the area available for work is very limited. Staircases have become an important workplace. The floors within the power plant are spaced widely apart, and workers frequently use the stairs to move between floors. However, there is a gap between the handrails and the stair surface of existing stairs. When workers carry goods up and down the stairs, items can easily fall through the gap, posing a risk of injury to workers working below. To avoid this, baffles are fixed between some stairs and handrails to seal the gap and prevent items from falling.

[0003] Although the baffle can shield objects, it will be damaged by repeated impacts from objects after long-term use. In some existing technologies, the baffle is an integrated design. When one section is damaged, the baffle needs to be removed and replaced. It is impossible to replace the damaged part separately, and the maintenance cost is high. Some existing technologies use a split design to reduce maintenance costs, but the baffles need to be fixed with bolts when splicing, which is more troublesome during disassembly and installation, reducing the efficiency of maintenance.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, the present invention provides a stair work baffle, comprising a stair main body 5 and a baffle A1, and further comprising: a connecting mechanism 2, the connecting mechanism 2 being arranged on the outer wall of the baffle A1; an adjusting mechanism 4, the adjusting mechanism 4 being arranged in the inner wall of the baffle A1; a supporting mechanism 3, the supporting mechanism 3 being arranged on the outer wall of the adjusting mechanism 4; and a handrail 6, the handrail 6 being fixedly connected to the top outer wall of the stair main body 5;

[0031] Among them, the connecting mechanism 2 includes a connecting block 21, the inner wall of which is elastically connected to the protrusion 24 through a return spring 25; the supporting mechanism 3 includes a supporting rod 32, the outer wall of which is hinged with an inner rod 33; the adjusting mechanism 4 includes a baffle B41, the inner wall of which is elastically connected to the insert block 45 through an elastic member B46.

[0032] The above scheme is adopted: baffle A1 and baffle B41 constitute the main body of the stair operation baffle, and baffle A1 and baffle B41 can be installed between the stair main body 5 and the handrail 6, and have a certain blocking effect on the gap to prevent objects from falling from both sides of the stair main body 5. On both sides of the baffle, baffle A1 can be fixed to one end of the handrail 6 by bolts or welding, and the other end of the handrail 6 can be fixed to the baffle B41 in the above manner; the connecting mechanism 2 can facilitate the splicing and fixing of the two groups of baffles A1 and baffle B41. When the baffle A1 or baffle B41 is damaged due to falling objects, the modular design can remove and replace one group of baffles A1 and baffle B41 separately, reducing maintenance costs.

[0033] like Figures 3 to 5 As shown, the inner wall of the connecting block 21 is slidably connected to the movable plate 22, the outer wall of the movable plate 22 is fixedly connected to the abutment rod 23, the inner wall of the protrusion 24 is provided with a sliding groove 26, the outer wall of the movable plate 22 is fixedly connected to the fixed block 27, the inner wall of the baffle B41 is provided with a groove 28, and the inner wall of the baffle A1 is provided with a limiting component.

[0034] The above solution is adopted: the outer wall of the movable plate 22 is flush with the outer wall of the connecting block 21, and the outer wall of the connecting block 21 is provided with an empty slot, the length of which is slightly longer than the long side of the connecting block 21; the end of the abutting rod 23 is provided with an inclined surface, and the abutting rod 23 is always in contact with the inner wall of the slide 26, and the slide 26 is provided with an inclined surface section and a straight surface section. Under normal conditions, the return spring 25 keeps the protrusion 24 in a pop-up state due to the elastic force, such as Figure 3 As shown, at this time, the inclined surface of the abutment rod 23 fits with the inclined surface section of the slide groove 26; through the engagement of the protrusion 24 in the outer wall connection mechanism 2 of one group of baffles A1 with the groove 28 on the outer wall of another group of baffles B41, one group of baffles A1 and the other group of baffles B41 can be spliced ​​and fixed.

[0035] like Figures 3 to 5 As shown, the connecting block 21 is fixedly connected to the outer wall of the baffle A1, one end of the return spring 25 is fixedly connected to the outer wall of the protrusion 24, and the other end of the return spring 25 is fixedly connected to the inner wall of the connecting block 21. The protrusion 24 is slidably connected in the inner wall of the connecting block 21, the protrusion 24 is engaged with the groove 28, the abutment rod 23 is in contact with the inner wall of the slide groove 26, and the abutment rod 23 and the fixed block 27 are both slidably connected to the inner wall of the baffle A1.

[0036] With the above solution, when the operator presses the movable plate 22 inward, the movable plate 22 drives the abutting rod 23 to move synchronously toward the inner wall of the connecting block 21, and the inclined surface of the abutting rod 23 squeezes the inner wall of the inclined surface section of the chute 26. Since the abutting rod 23 can only move in a straight line along the inner wall of the connecting block 21, the pressure generated on the inclined surface section of the chute 26 drives the protrusion 24 to move toward the inner wall of the connecting block 21, and the protrusion 24 compresses the return spring 25. At this time, the state is as follows: Figure 4 As shown, Figure 4 The middle return spring 25 is not shown; when the protrusion 24 is completely moved into the inner wall of the connecting block 21, the abutment rod 23 moves to the straight section of the slide groove 26. At this time, one group of baffles A1 can be spliced ​​with another group of baffles B41, so that the position of the protrusion 24 corresponds to the position of the groove 28. Through the elastic force of the return spring 25 itself, the protrusion 24 can be popped out and engaged with the groove 28, thereby completing the fixation between the baffle A1 and the baffle B41.

[0037] like Figures 4 and 5As shown, the limiting assembly includes a fixed rod 205, the outer wall of the fixed rod 205 is fixedly connected to the frustum B204, the outer wall of the fixed rod 205 is elastically connected to the frustum A203 through a connecting spring 206, and the inner wall of the fixed block 27 is elastically connected to the wedge block 202 through an elastic member A201.

[0038] Using the above solution: Figure 4 As shown, when the movable plate 22 is pressed inward and drives the two sets of protrusions 24 to move toward the inner wall of the connecting block 21, the fixed block 27 will move synchronously with the movable plate 22 and drive the wedge block 202 to move. The inclined surface of the wedge block 202 contacts the inclined surface of the truncated cone B204. Since the truncated cone B204 is in a fixed state, the wedge block 202 will be squeezed by its inclined surface and move toward the inner wall of the fixed block 27, compressing the elastic member A201. When the movable plate 22 and the fixed block 27 move to the point where the wedge block 202 and the truncated cone B204 are in contact, the wedge block 202 will be squeezed by its inclined surface and move toward the inner wall of the fixed block 27, compressing the elastic member A201. When the table B204 is out of contact, the elastic member A201 drives the wedge block 202 to pop out, and the straight surface of the wedge block 202 fits with the straight surface of the round table B204, which can limit the fixed block 27 and the movable plate 22; by setting the connecting spring 206, there is always a distance between the round table A203 and the round table B204; in this state, the abutment rod 23 is always in contact with the straight surface section of the slide groove 26, limiting the protrusion 24, and keeping the protrusion 24 in the inner wall of the connecting block 21.

[0039] like Figures 4 and 5 As shown, the fixing rod 205 is fixedly connected to the inner wall of the baffle A1, one end of the elastic member A201 is fixedly connected to the outer wall of the wedge block 202, the other end of the elastic member A201 is fixedly connected to the inner wall of the fixing block 27, the wedge block 202 is slidably connected to the inner wall of the fixing block 27, the frustum B204 is slidably connected to the outer wall of the fixing rod 205, and the two ends of the connecting spring 206 are fixedly connected to the outer walls of the frustum A203 and the fixing rod 205 respectively.

[0040] With the above solution: when the protrusion 24 is in the inner wall of the connecting block 21, it is easy to splice the baffle A1 and the baffle B41, and the operator does not need to press the movable plate 22 for a long time to maintain the position of the protrusion 24; when the position of the protrusion 24 and the groove 28 between the baffle A1 and the baffle B41 corresponds to each other, the movable plate 22 can be pressed inward to drive the fixed block 27 and the wedge block 202 to move inward, and the inclined surface of the wedge block 202 contacts the outer wall of the frustum A203, as shown in FIG. Figure 5As shown, the frustum A203 is slidably connected to the outer wall of the fixed rod 205, but it can only move to the left and cannot move to the right, thereby squeezing the inclined surface of the wedge block 202, causing it to move again to the inner wall of the fixed block 27, and the abutment rod 23 will continue to move inward along the straight section of the slide groove 26 to maintain the position of the protrusion 24; during the movement of the movable plate 22 and the fixed block 27, the wedge block 202 will first break away from the outer wall of the frustum A203, and then pop up and reset under the elastic force of the elastic member A201, so that its straight surface contacts the right outer wall of the frustum A203. At this time, the operator can insert his finger into the gap between the movable plate 22 and the outer wall of the connecting block 21, pull the movable plate 22 outward, and the fixed block 27 and the wedge block 202 move outward synchronously, and the wedge block 2 The straight surface of 02 drives the table A203 to move synchronously, and the connecting spring 206 is stretched. When the table A203 moves to fit the outer wall of the table B204, the wedge block 202 moves along the inclined surface of the table A203 and the table B204. After the wedge block 202 is out of contact with the table B204, it is reset under the elastic force of the elastic member A201. The table A203 is reset under the elastic force of the connecting spring 206. At this time, the movable plate 22 is also pulled out and reset by the operator. The abutment rod 23 moves from the straight surface section of the slide groove 26 to the inclined surface section. The protrusion 24 pops out and resets under the elastic force of the reset spring 25, and can be engaged with the groove 28. The inclined surface section of the slide groove 26 contacts and squeezes the inclined surface of the abutment rod 23, so that the abutment rod 23 and the movable plate 22 remain in a fixed state.

[0041] like Figures 7 and 8 As shown, the outer wall of the baffle B41 is slidably connected to a slider 38, the inner wall of the slider 38 is elastically connected to the round rod 30 through a telescopic spring 39, the inner wall of the slider 38 is hinged to a sleeve rod 34, the inner wall of the sleeve rod 34 is provided with a buffer groove 35, the inner wall of the sleeve rod 34 is elastically connected to a rubber pad 37 through a buffer spring 36, and the outer wall of the baffle B41 is provided with a circular groove 31.

[0042] The above scheme is adopted: when the support mechanism 3 is unfolded, it can provide an oblique support effect on the side edges of the baffle A1 and the baffle B41, and provide a certain buffering effect to prevent the baffle A1 and the baffle B41 from being impacted when objects fall, causing them to fall or be damaged at the connection, and the protection effect is better; the support mechanism 3 can be folded into the inside of the baffle B41, which saves space when the operator carries the baffle A1 and the baffle B41, and can be unfolded for support after the installation of the baffle A1 and the baffle B41 is completed; the slider 38 can move up and down on the outer wall of the baffle B41, and is clamped with the upper and lower sets of circular grooves 31 through the round rod 30, and the slider 38 can be fixed in the upper and lower positions to fold or unfold the support mechanism 3.

[0043] like Figures 7 and 8As shown, one end of the telescopic spring 39 is fixedly connected to the outer wall of the round rod 30, the other end of the telescopic spring 39 is fixedly connected to the inner wall of the slider 38, the round rod 30 is slidably connected in the inner wall of the slider 38, the round rod 30 is clamped in the circular groove 31, and the rubber pad 37 is fixedly connected to the outer wall of the inner rod 33; the inner rod 33 is slidably connected in the inner wall of the sleeve rod 34, one end of the buffer spring 36 is fixedly connected to the outer wall of the rubber pad 37, the other end of the buffer spring 36 is fixedly connected to the inner wall of the sleeve rod 34, the rubber pad 37 is in contact with the buffer groove 35, and the support rod 32 is hinged to the outer wall of the baffle B41.

[0044] When the support rod 32 is turned to the horizontal position, the round rod 30 corresponds to the position of the circular groove 31 below, and under the elastic force of the telescopic spring 39, it pops out and engages with the circular groove 31, unfolding the support mechanism 3; since objects generally fall from the inside to the outside of the stair body 5, an outward force is exerted on the baffle A1 and the baffle B41, and at this time the sleeve rod 34 moves on the outer wall of the inner rod 33, the buffer spring 36 is forced to contract, and the buffer groove 35 squeezes the rubber pad 37 to cause it to deform. The rubber pad 37 can increase the friction between the sleeve rod 34 and the inner rod 33, thereby playing a damping effect, thereby reducing the amplitude of shaking caused by impact and improving the buffering effect.

[0045] like Figure 6 As shown, the inner wall of the baffle B41 is slidably connected to a pull rod 42, the outer wall of the pull rod 42 is fixedly connected to a cross bar 43, the insert block 45 is hinged to the outer wall of the cross bar 43 through a hinge rod 44, and a slot 47 is opened on the inner wall of the baffle A1.

[0046] The above solution is adopted: the top end of the pull rod 42 passes through the top outer wall of the baffle A1, and the operator can pull the pull rod 42 upward to contact the fixation between the baffle B41 and the baffle A1, and then move the baffle B41 up and down on the inner wall of the baffle A1, so that it can be flexibly adjusted according to the height of each step of the stair body 5, ensuring that no gap will be generated below when used on stair bodies 5 of different heights; there are multiple groups of slots 47, and the baffle B41 can be limited by the engagement of the insert block 45 with the slot 47, so that the baffle B41 can be fixed in multiple positions to improve adaptability.

[0047] like Figure 6As shown, the baffle B41 is slidably connected to the inner wall of the baffle A1, the two ends of the hinged rod 44 are hinged to the outer walls of the cross bar 43 and the plug block 45 respectively, the plug block 45 is slidably connected to the inner wall of the baffle B41, one end of the elastic member B46 is fixedly connected to the outer wall of the plug block 45, and the other end of the elastic member B46 is fixedly connected to the inner wall of the baffle B41, and the plug block 45 is snap-fitted to the slot 47.

[0048] The above solution is adopted: under normal circumstances, the elastic part B46 will keep the plug 45 in a pop-up state due to the elastic force, and when the pull rod 42 is pulled upward, the cross bar 43 moves synchronously, which will drive the hinged rod 44 to flip, and the hinged rod 44 drives the plug 45 to move. Since the plug 45 can only move horizontally in the inner wall of the baffle B41, the hinged rod 44 will flip and drive the plug 45 to move into the inner wall of the baffle B41, compressing the elastic part B46 and disengaging from the slot 47, so that the baffle B41 can be adjusted up and down; when adjusted to the appropriate position, the elastic part B46 drives the plug 45 to pop out and snap into the slot 47 to complete the fixation, and the operation is simple.

[0049] The working principle and use process of the present invention:

[0050] The operator can first adjust the length of the baffle B41 according to the height of each step of the stair main body 5; pull the pull rod 42 at the top of the baffle B41 upwards, driving the cross bar 43 and the hinged rod 44 to flip, and the movable plug block 45 retracts into the baffle B41, releasing the engagement with the slot 47 on the inner wall of the baffle A1, and then move the baffle B41 up and down to adjust it to the height suitable for the stair steps, release the pull rod 42, and the elastic part B46 pushes the plug block 45 out and snaps into the corresponding slot 47 to complete the height fixation.

[0051] Then, the baffle body consisting of two groups of baffles A1 and baffle B41 is installed on both sides of the handrail 6 by bolts or welding. The baffle A1 in one group of baffles is fixed to the handrail 6 at one end, and the baffle B41 in the other group of baffles is fixed to the handrail 6 at the other end. Then, the middle groups of baffles are installed. You can first press the outer wall moving plate 22 of one group of baffles A1 to drive the abutment rod 23 to move inward, and squeeze the protrusion 24 through the inclined section of the slide groove 26 to retract it into the connecting block 21. The reset spring 25 is compressed. When pressing the moving plate 22, the fixed block 27 drives the wedge block 202 to move, and its inclined surface It is squeezed with the truncated cone B204 and the elastic part A201 is compressed. When the wedge block 202 is directly in contact with the truncated cone B204, the fixed block 27 and the movable plate 22 are limited to fix the position of the protrusion 24, so that the movable plate 22 does not need to be pressed all the time for operation; then the grooves 28 of one group of baffles B41 are aligned with the protrusions 24 in the outer wall connecting blocks 21 of another group of baffles A1, and the movable plate 22 is continued to be pressed. The wedge block 202 is in direct contact with the truncated cone A203. At this time, the movable plate 22 can be pulled outward to reset the connecting mechanism 2 as a whole, and the protrusion 24 pops out and fits into the groove 28 to complete the fixation.

[0052] In the above manner, multiple sets of baffles A1 and baffles B41 are completely spliced ​​together. Baffles A1 and baffles B41 can close the gap below the handrail 6 and the stair body 5 to prevent objects from falling; then the round rod 30 can be pulled outward to disengage it from the circular groove 31, and the slider 38 can be moved downward to drive the sleeve rod 34, the inner rod 33 and the support rod 32 to flip to a horizontal state, release the round rod 30, and the telescopic spring 39 pushes it to be stuck in the circular groove 31 below to complete the deployment of the support mechanism 3. When an object hits the baffle, the sleeve rod 34 moves along the inner rod 33, the buffer spring 36 is compressed, and the buffer groove 35 squeezes the rubber pad 37 to cause deformation, thereby reducing shaking through friction damping and alleviating impact force.

[0053] If a set of baffles A1 and B41 are damaged due to excessive impact after long-term use, the damaged baffles can be separated from the other baffles by pressing the movable plate 22 to disengage the protrusion 24 from the groove 28, and then new baffles can be installed and the splicing and fixing steps can be repeated to ensure that the protrusion 24 and the groove 28 are firmly engaged.
