Description

Technical field:

[0001] The utility model relates to the technical field of construction equipment, and more particularly to a bridging device for a construction elevator. Background technology:

[0002] Construction hoists are mainly used to lift the required building materials to the corresponding floors and place the building materials on the floor plates at the corresponding floors for construction workers to take.

[0003] However, in order to ensure that the elevator cage can be raised and lowered normally, there needs to be a certain gap (i.e. spacing) between it and the floor plate. Otherwise, when the cage is raised and lowered, the two will collide due to the shaking problem, affecting the normal lifting and lowering, posing a safety hazard.

[0004] However, the gap between the two also brings disadvantages to movement. For example, when a cart is placed in the cage, when it is pushed out of the cage, the wheels of the cart will get stuck in the gap between the floor plate and the cage, affecting normal pushing and movement, resulting in inconvenience in use. Utility model content:

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a bridging device for a construction elevator, which can flip the bridging plate when pushing a cart or transporting building materials, thereby covering the gap between the floor plate and the cage, ensuring normal pushing of the cart or transporting of building materials, and having a good use effect.

[0006] The solution of the utility model to solve the technical problem is:

[0007] A bridging device for a construction elevator includes an elevator cage and a floor plate on the right side of the elevator cage. The elevator cage has an entrance and exit near the floor plate, and a bridging plate is movably connected to the top of its bottom plate. A telescopic support plate is provided at the bottom of the bridging plate, and the right bottom surface of the telescopic support plate rests on the left top surface of the floor plate.

[0008] The lower parts of the front and rear side panels of the elevator cage are fixed with connecting blocks, the flip connecting blocks are movably connected to the corresponding connecting blocks through a hinge shaft, the right ends of the two flip connecting blocks are fixed with connecting plates, and the left top surface of the bridging plate is fixed on the bottom surfaces of the two connecting plates.

[0009] The bottom surface of the bridge plate is provided with a lower support shell, and a placement slot is formed in the middle of the top surface of the lower support shell. The right end of the placement slot extends out of the right end surface of the lower support shell, and the telescopic support plate is inserted into the placement slot, and the right end of the telescopic support plate extends out of the right end of the placement slot.

[0010] A plurality of waist-shaped sockets are formed on the front and rear side walls of the telescopic support plate, and positioning side sockets are formed on the front and rear inner side walls of the right end of the slot. The positioning side sockets correspond to the waist-shaped sockets, and the plug-in rod is inserted into the positioning side sockets. The inner end of the plug-in rod extends out of the inner end of the corresponding positioning side socket and is inserted into the corresponding waist-shaped socket.

[0011] The outer end of the plug rod extends out of the outer end of the corresponding positioning side socket and forms or fixes a limit plate, which is pressed against the outer side wall of the front side plate or the rear side plate of the lower support shell.

[0012] A plurality of recessed holes are formed on the outer wall of the front side plate or the rear side plate of the lower supporting shell corresponding to the inner side of the limiting plate. The permanent magnet blocks are nested in the corresponding recessed holes and fixed on the inner side walls of the recessed holes. The inner side wall surface of the limiting plate is pressed against the outer side wall surface of the corresponding permanent magnet block and is adsorbed and fixed.

[0013] The outstanding effects of the utility model are:

[0014] Compared with the existing technology, it can flip the bridge plate when pushing a cart or transporting building materials, thereby covering the gap between the floor plate and the cage, ensuring normal pushing of the cart or transporting of building materials, and having a good use effect.

[0015] At the same time, a retractable support plate is provided under the bridging plate, and the extension length can be adjusted as needed, so as to meet the needs of covering and bridging different gaps. It has a wide range of applications and good effects. Description of the drawings:

[0023] Figure 8yes Figure 1 A partial enlarged view of . Specific implementation method:

[0024] For example, see Figures 1 to 8 As shown, a bridging device for a construction elevator includes an elevator cage 10 and a floor slab 20 at the right side of the elevator cage 10 (the floor slab 20 can be a cast-in-place floor slab or a construction platform cast on the outside of the floor slab for being close to the elevator cage 10). The elevator cage 10 has an entrance and exit near the floor slab 20, and a bridging plate 30 is movably connected to the top of its bottom plate. A telescopic support plate 40 is provided at the bottom of the bridging plate 30, and the right bottom surface of the telescopic support plate 40 rests on the left top surface of the floor slab 20.

[0025] Furthermore, connecting blocks 11 are welded and fixed to the lower inner sides of the front and rear side panels of the elevator cage 10, and the flip connecting blocks 12 are movably connected to the corresponding connecting blocks 11 through a hinge shaft. The right ends of the two flip connecting blocks 12 are fixed with connecting plates 13, and the left top surface of the bridging plate 30 is fixed to the bottom surfaces of the two connecting plates 13.

[0026] The front connecting plate 13 is a bent plate, which includes a vertical plate portion with a rightward-bent portion formed at its rear end. The vertical plate portion is welded to the right end of the front flip connecting block 12. A vertical push rod 2 is welded to the vertical plate portion. A gripping rod 3 is fixed to the left side wall of the top end of the vertical push rod 2.

[0027] Specifically, the bottom surface of the bridge plate 30 includes a lower support housing 31. A placement slot 32 is formed in the middle of the top surface of the lower support housing 31. The right end of the placement slot 32 extends beyond the right end surface of the lower support housing 31. The telescopic support plate 40 is inserted into the placement slot 32, with the right end of the telescopic support plate 40 extending beyond the right end of the placement slot 32. The top surface of the telescopic support plate 40 is adjacent to the top surface of the placement slot 32, and the bottom surface of the telescopic support plate 40 is pressed against the bottom surface of the placement slot 32.

[0028] Furthermore, the telescopic support plate 40 has a plurality of waist-shaped insertion holes 41 formed on both the front and rear side walls. Positioning side insertion holes 33 are formed on both the front and rear inner side walls at the right end of the slot 32. The positioning side insertion holes 33 correspond to the waist-shaped insertion holes 41. A plug rod 42 is inserted into the positioning side insertion holes 33. The inner end of the plug rod 42 extends out of the inner end of the corresponding positioning side insertion hole 33 and is inserted into the corresponding waist-shaped insertion hole 41. The plug rod 42 corresponds in shape to the waist-shaped insertion hole 41.

[0029] Furthermore, the outer end of the connecting rod 42 extends out of the outer end of the corresponding positioning side socket 33 and forms or fixes a limit plate 43, which presses against the outer side wall of the front side plate or the rear side plate of the lower support shell 31.

[0030] A plurality of recessed holes are formed on the outer side wall of the front side plate or the rear side plate of the lower supporting shell 31 corresponding to the inner side of the limiting plate 43. The permanent magnet block 1 is nested in the corresponding recessed hole and fixed on the inner side wall of the recessed hole. The inner side wall surface of the limiting plate 43 is pressed against the outer side wall surface of the corresponding permanent magnet block 1 and is adsorbed and fixed.

[0031] When this embodiment is in use, when the elevator cage 10 is being raised or lowered, the bridge plate 30 can be flipped up. At this time, the bottom end of the gripping rod 3 is pressed against the top surface of the bottom plate of the elevator cage 10 to ensure support.

[0032] Among them, a second permanent magnet block 5 can be fixed on the top surface of the bottom plate of the elevator cage 10 corresponding to the bottom end of the holding rod 3, and the bottom end of the holding rod 3 is pressed against the top surface of the second permanent magnet block 5 to achieve fixation and prevent the bridge plate 30 from flipping down.

[0033] When it reaches the corresponding floor plate 20, you can manually hold the holding rod 3 and flip the vertical push rod 2 upward. At this time, the bridge plate 30 flips down, which will make the right bottom surface of the telescopic support plate 40 lean against the left top surface of the floor plate 20 to achieve support. Among them, the right end top surface of the bridge plate 30 is an inclined surface inclined to the right and downward, and the right end top surface of the telescopic support plate 40 is formed with an inclined surface inclined to the right and downward. At the same time, the right end bottom surface of the telescopic support plate 40 protrudes downward, and its bottom surface is flush with the bottom surface of the lower support shell 31. Under normal circumstances, the right end of the telescopic support plate 40 extends out of the right end of the bridge plate 30 to ensure that the inclined surface of the right end top surface of the telescopic support plate 40 corresponds to the inclined surface of the right end of the bridge plate 30, so that the cart can be pushed along the inclined surface of the right end top surface of the telescopic support plate 40 and the inclined surface of the right end of the bridge plate 30.

[0034] When the gap between the corresponding floor plate 20 and the bottom plate of the elevator cage 10 is relatively large, you can hold the two limit plates 43 and pull them outward so that the inner end of the connecting rod 42 extends out of the corresponding waist-shaped socket 41. At this time, you can move the telescopic support plate 40 to the right and extend it to a sufficient length. Then, the inner end of the connecting rod 42 is inserted into the corresponding waist-shaped socket 41, so that the inner side wall of the limit plate 43 is pressed against the outer wall of the corresponding permanent magnet block 1 and adsorbed and fixed, so that the bottom surface of its right end is pressed against the left top surface of the corresponding floor plate 20 to achieve support. At this time, you can push or walk along the bridge plate 30 and the telescopic support plate 40 to transport building materials. It is easy to carry, easy to operate, and has good use effect.

Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations. Any simple modifications, equivalent variations, and modifications to the above embodiments based on the technical essence of the present invention shall be deemed to fall within the scope of protection of the present invention.
