Description

Technical Field

[0001] The present invention relates to mechanical devices in the field of industrial building fire protection and energy-saving technology, mainly to a multifunctional device for fire protection and energy saving in industrial buildings such as production workshops and storage facilities in the industrial and circulation fields. Specifically, it relates to a lifting device and its installation structure that have the functions of assisting object transfer and unloading and opening and closing logistics wall holes. Background Art

[0002] In industrial buildings, such as production workshops and storage facilities in the industrial and distribution sectors, it's common to use walls to separate two functional areas. Logistics openings are often located at appropriate heights in the wall, flanked by primary and secondary conveyors to facilitate the continuous transport of bagged or boxed items through the wall. However, to meet functional, fire-fighting, cleanliness, and temperature and humidity requirements, fire-resistant lifting doors are often installed in the logistics wall openings. These doors can be raised at any time to pass through the gap between the primary and secondary conveyors, sealing the wall opening.

[0003] However, actual application cases have shown that this method objectively results in a large distance between the head and tail of the main and slave conveyors at both ends of the wall. Especially when conveying relatively small bag-type or box-type objects, phenomena such as object jamming, jumping, and offset are inevitable, causing continuous conveying interruptions or even accidents.

[0004] The present invention aims to provide a lifting device for a production workshop or facility that is separated into two functional areas, which can not only effectively assist in the transportation of objects but also smoothly open and close logistics wall holes, based on the requirements of function, fire protection, cleanliness, temperature and humidity.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Comparative Example (Prior Art):

[0038] In industrial buildings, such as production workshops and storage facilities in the industrial and distribution sectors, it's common to use walls to separate two functional areas. Logistics openings are often located at appropriate heights in the wall, flanked by primary and secondary conveyors to enable the continuous transport of bagged or boxed items through the wall. However, to meet functional, fire-fighting, cleanliness, and temperature and humidity requirements, the conventional solution is to install a separate fire-resistant lifting door in the logistics wall opening, which can be raised at any time to pass through the gap between the primary and secondary conveyors to seal the wall opening.

[0039] However, actual application cases show that this method objectively causes a large distance between the head and tail of the main and slave conveyors at both ends of the wall, as shown in the attached Figure 8 As shown in (a), x1+x2+x3, especially when conveying relatively small bag-type or box-type objects, it is difficult to avoid phenomena such as object jamming, jumping, and deviation, which may cause continuous conveying interruption or even accidents.

[0040] Example 1:

[0041] The installation structure of the lifting device with the functions of assisting object transfer and unloading and opening and closing the logistics wall hole is as follows: Figure 1 As shown:

[0042] The lifting device mainly includes a lifting component 1, a door frame 2, a base 3, an electric push rod 4, and a support base 5.

[0043] Lifting component 1: Figure 2As shown, it is composed of a triangular steel frame 11, a support 12, a door body 13, a roller 14 and a short shaft 15. Among them:

[0044] Triangular steel frame 11: Figure 7 As shown, two cross beams 111, three cross beams 115, and four cross beams 118 are made of channel steel (or rectangular steel); two diagonal braces 112 are made of channel steel (or rectangular steel); two uprights 113 are made of channel steel (or rectangular steel); two ribs 117 are made of steel plates; four connecting plates 114 and one connecting plate 116 are made of flat steel (or angle steel).

[0045] Support 12: Figure 3-4 As shown, it is fork-shaped and is welded from a bottom plate and two side plates; holes are opened on the side plates to match the pins (purchased standard parts).

[0046] Door 13: Customized with fireproof board. Figure 3 、 4 、5.

[0047] Roller 14: See Figure 3 、 4 , 5, four in total, each roller 14 has a built-in bearing and a sleeve.

[0048] Mast 2: Figure 6 As shown, it mainly consists of an outer rail 21, a first channel steel 22, a second channel steel 23, an inner rail 24 and a sealing strip 25 lining the inner rail 24.

[0049] Outer rail 21: gate-shaped, made of three channel steels.

[0050] Inner rail 24: Gate-shaped, made of three channel-shaped steels. The outer rail and the inner rail are attached together.

[0051] Sealing strip 25: It is a purchased product and is pasted on three sides and the entire length of the inner rail 24 groove.

[0052] Door frame 2: The outer rail 21 and the inner rail 24 are welded into one through the first channel steel 22 and the second channel steel 23.

[0053] Base 3: As Figure 1-2 As shown, it is welded by channel steel (or steel section).

[0054] Electric push rod 4: It is the power source for the lifting of this device. According to the lifting component 1, the transfer conveyor and the weight of the conveyed object, you can choose a product from a professional manufacturer.

[0055] Support seat 5: Figure 1 As shown in (b), it is fork-shaped and is welded from a bottom plate and two side plates; holes are opened on the side plates to match the pins (purchased standard parts).

[0056] Working principle of this device:

[0057] 1. This device uses an electric push rod 4 as a power source. When working, it drives the lifting component 1 up and down, playing the dual functions of lifting and unloading the conveyor and opening and closing the logistics wall hole. That is:

[0058] Under normal production conditions, the logistics wall holes of the production workshop, storage facilities and other building partition walls are open, the electric push rod 4 is in the initial position, the platform surface of the lifting component 1 is at the same level as the platform surface of the first conveyor and the second conveyor, and the objects are transported normally through the logistics wall hole through the first conveyor, the transfer conveyor and the second conveyor. Figure 1 (b) "Initial state, logistics wall hole is open" is shown in the legend; when the logistics wall hole needs to be closed, the first conveyor, the transfer conveyor and the second conveyor are suspended, and at the same time a signal is sent to start the electric push rod 4, lifting the lifting component 1 to the set height, and the door body 14 then seals the logistics wall hole, thereby maximally blocking the flow of air or dust between the functional areas on both sides of the wall, as shown in FIG. Figure 1 (a) “Lifting state, logistics wall hole closed” as shown in the legend.

[0059] The objects transported by this device are usually bags, boxes or other items with relatively regular volumes, and are particularly suitable for smaller items.

[0060] When the device is used, the transfer conveyor placed on the lifting assembly 1 can adopt different types of conveying devices such as belt conveyors, conveyor rollers, plate conveyors, etc., to form an independent yet related logistics conveying line with the first and second conveyors.

[0061] In order to adapt to the flexibility and rationality of the layout of the internal logistics line of the workshop, when using this device, the first conveyor can be arranged horizontally in a straight line with the transfer conveyor, or at a 90-degree angle.

[0062] This device, the first conveyor, the transfer conveyor and the second conveyor can realize automatic system control through electrical interlocking according to actual needs.

[0063] Key points for installing this device:

[0064] When the device is installed, the two pairs of rollers 14 of the lifting assembly 1 are placed in the outer rails 21 of the door frame 2, and the door body 13 of the lifting assembly 1 is placed in the inner rails 24 of the door frame 2; thus, the lifting assembly 1 can move up and down along the door frame 2, playing the dual functions of lifting and unloading the conveyor and opening and closing the logistics wall hole.

[0065] When the device is installed, the door frame 2 faces the logistics wall hole and is close to the wall. The first channel steel 22 and the second channel steel 23 are fixed to the wall and the floor respectively by welding or bolting.

[0066] When the device is installed, the base 3 is fixed on the floor, and the support base 5 carries the loads such as the electric push rod 4 and the lifting component 1.

[0067] When the device is installed, the lower ear seat of the electric push rod 4 is connected to the support seat 5 through a pin shaft (purchased standard part), and the upper fork head of the electric push rod 4 is connected to the support 12 of the lifting assembly 1 through a pin shaft.

[0068] When installing this device, the bottom plate of the support seat 5 is fixed to the base 3 by welding or bolting; the side plate of the support seat 5 is connected to the lower ear seat of the electric push rod 4 through a pin (purchased standard part).

[0069] When the lifting assembly 1 is assembled, the triangular steel frame 11 is connected to the door body 13 through the connecting plate 114 and the connecting plate 116 .

[0070] When the lifting assembly 1 is assembled, the bottom plate of the support 12 is welded to the lower end surface of the middle crossbeam (115) of the triangular steel frame 11; the side plate of the support 12 is connected to the upper fork of the electric push rod 4 through a pin (purchased standard part).

[0071] When the lifting assembly 1 is assembled, the door body 13 is fixed to the connecting plates 114 and 116 on the triangular steel frame 11 by bolts or welding.

[0072] When the lifting assembly 1 is assembled, the four rollers 14 are fixed to the upper and lower ends of the vertical rods 113 on both sides of the triangular steel frame 11 through short shafts.

[0073] When the door frame 2 is assembled, the sealing strip 25 is pasted on three sides and the entire length of the inner rail 24 groove to enhance the airtightness of the door body 14 when it is in the closed wall hole state.

[0074] The advantages or positive effects of the present invention compared with the prior art and their causal relationship are as follows:

[0075] Combined with attachment Figure 8 As shown in Figures (a) and (b), the application of this device, through the lifting assembly and its door body, with its auxiliary unloading and opening and closing logistics wall hole functions, can achieve the following: 1. When the wall hole needs to be closed, the lifting assembly is lifted, and its upper door body gradually closes the wall hole, thereby blocking the flow of air or dust generated by the existence of the logistics wall hole; 2. During normal operation, the gap is minimized due to the maximum proximity between the conveyors on both sides of the wall, as shown in the attached figure. Figure 8 As shown in (b), x1+x2 can transport objects of all sizes smoothly and reliably.

[0076] Depend on Figure 8Comparison between (a) and 8(b) shows that the application of this device reduces the x3 dimension, that is, reduces the thickness of the fire-proof lifting door. This effectively overcomes the disadvantages of conventional technical solutions and embodies the advantages of practicality, adaptability and reliability.

[0077] The application of this device can be combined with the conveying system consisting of the first conveyor, the transfer conveyor and the second conveyor to achieve system automatic control and remote real-time monitoring through electrical interlocking according to actual needs.
