Description

Technical Field

[0001] This utility model relates to the field of large-volume concrete pouring construction equipment, and in particular to a material discharge device for a tower-type pouring equipment supply line. Background Technology

[0002] In large-scale water conservancy and hydropower projects, to meet flood control requirements, the excavation of the foundation pit must be completed simultaneously with the pouring of large-volume concrete for the bottom structure within a single dry season. The concrete pouring process is time-sensitive and requires high strength. The construction period is extremely tight, and equipment such as tower cranes, top-mounted concrete placing booms, and mobile concrete placing booms are generally used for hoisting and pouring. Tower cranes combine a tower crane with a concrete placing boom or placing pipe, using the tower crane to change the pouring position, angle, and length of the placing belt or placing pipe. Refer to CN105350780A for information on commonly used combined pouring equipment and its construction methods.

[0003] Since the placing boom or placing pipe is suspended on the tower crane and the feeding end is at a high height, a feeding line needs to be set up to feed the placing boom or placing pipe. To ensure that the feeding line and the placing boom are compatible in terms of material transfer, a horizontal conveyor belt is usually installed on the lifting frame connected to the end of the placing boom. However, as the pouring height is adjusted, the lifting frame needs to be adjusted up and down. At this time, the angle of the feeding line will also change. Therefore, it is urgent to solve the problem of connecting the material discharge end of the feeding line with the material drop of the conveyor belt. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a material discharge device for a tower-type casting equipment, which is used to connect with the transfer belt on the lifting frame, so as to ensure that the material discharged from the material supply line falls onto the transfer belt, and can be adapted to the end of the material supply line.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a material discharge device for a tower-type casting equipment feeding line, including a frame, the frame straddling a conveyor belt, a receiving hopper on the frame, a discharge hopper rotatably connected to the receiving hopper, an installation frame on the outside of the discharge hopper, a hinge seat on the installation frame, and the hinge seat being hinged to the truss at the discharge end of the feeding line by a pin.

[0006] In a preferred embodiment, the feeding hopper and the receiving hopper are rotatably connected by a slewing bearing, and the feeding hopper and the receiving hopper are respectively connected to the inner ring and the outer ring of the slewing bearing, with the lower end of the feeding hopper fitted inside the receiving hopper.

[0007] In a preferred embodiment, both the discharge hopper and the receiving hopper are provided with connecting flanges, which are connected to the inner or outer ring of the slewing bearing by bolts.

[0008] In a preferred embodiment, the frame includes two sets of bases, the lower ends of the two sets of support frames are connected to the bases, the upper end of the support frames is provided with a top mounting frame, the top mounting frame is provided with a through hole for the receiving hopper to pass through, and the top mounting frame is connected to the receiving hopper.

[0009] In a preferred embodiment, the support frame includes two sets of support plates, and the base is disposed between the two sets of support plates.

[0010] In a preferred embodiment, the base is provided with a fixing plate, and one side of the support frame is provided with an ear plate that is connected to the fixing plate by a pin.

[0011] In a preferred embodiment, a climbing frame is provided on the outside of the support frame.

[0012] In a preferred embodiment, the lower end of the receiving hopper is provided with a guide cylinder, which covers the outside of the receiving hopper and is made of a soft material.

[0013] In a preferred embodiment, the receiving hopper is provided with a scraper on the side near the downstream side of the transfer belt, and a material passage gap is provided between the scraper and the upper side of the transfer belt.

[0014] In a preferred embodiment, one side of the mounting bracket is provided with a hanging rope for connecting the pin.

[0015] The present invention provides a material discharge device for a tower-type casting equipment feeding line, which has the following beneficial effects:

[0016] 1. Because the outer mounting frame of the hopper is equipped with a hinge seat, it is convenient to connect with the truss at the discharge end of the feeding line by means of pins. When the height of the lifting frame is adjusted up and down, causing changes in the angle or position of the feeding line, the position of the hinge seat connected to the feeding line can be adjusted by rotating the hopper to ensure a reliable connection with the feeding line. At the same time, because the hopper is hinged to the feeding line, a good material drop connection is always maintained, ensuring the continuity of concrete delivery and avoiding material spillage or blockage caused by poor connection, thereby improving construction efficiency.

[0017] 2. The support frame includes two sets of support plates, and the base is set between the two sets of support plates. After the base is installed on the lifting kit, when hoisting this device, it is only necessary to set the base between the two sets of support plates to complete the positioning of the support frame.

[0018] 3. The climbing frame installed on the outside of the support frame facilitates operators to climb up and down to inspect, maintain and operate the equipment, thus improving construction safety.

[0019] 4. The soft guide cylinder installed at the lower end of the receiving hopper can buffer and guide the material when it falls, reduce the impact of the material on the conveyor belt, prevent material splashing, protect the conveyor belt, and extend its service life.

[0020] 5. The scraper installed on the downstream side of the receiving hopper near the conveyor belt has a material passage gap with the upper side of the conveyor belt, which can scrape the concrete on the conveyor belt and improve the uniformity of material supply.

[0021] 6. The hanging rope on one side of the mounting bracket for connecting the pins can effectively prevent the pins from falling off and being lost during disassembly or installation, ensuring the normal use of the equipment and reducing downtime and economic losses caused by lost pins.

Detailed Implementation

[0028] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0029] Example 1:

[0030] like Figures 1-4 As shown, a material discharge device for a tower-type casting equipment feeding line includes a frame 1, which is straddled on a conveyor belt 2 and located at the feed end of the conveyor belt 2. A receiving hopper 3 is mounted on the frame 1, and a discharge hopper 4 is rotatably connected to the receiving hopper 3. Specifically, as shown... Figure 1 and 3As shown, the feeding hopper 4 and the receiving hopper 3 are rotatably connected by a slewing bearing 9. The feeding hopper 4 and the receiving hopper 3 are respectively connected to the inner ring and the outer ring of the slewing bearing 9. The lower end of the feeding hopper 4 is fitted inside the receiving hopper 3. Both the feeding hopper 4 and the receiving hopper 3 are provided with connecting flanges 10, which are connected to the inner ring or the outer ring of the slewing bearing 9 by bolts.

[0031] The outer side of the feeding hopper 4 is provided with a mounting frame 5, and the mounting frame 5 is provided with a hinge seat 6. The hinge seat 6 is hinged to the truss at the discharge end of the feeding line 8 through a pin 7. By hinged to the feeding line 8 and the hinge seat 6, the feeding line 8 can swing relative to the feeding hopper 4, so that the feeding hopper 4 can be adapted to the feeding line 8 when the angle of the feeding line is adjusted.

[0032] When the feed line 8 is connected to the hinge seat 6, the feed hopper 4 is rotated relative to the receiving hopper 3 according to the discharge position of the feed line, so that the hinge seat 6 can rotate to a position where it can reliably connect with the feed line 8.

[0033] Preferably, the mounting frame 5 is provided with a hanging rope 11 for connecting the pin 7 on one side. When the feed line 8 is disconnected from the hinge seat 6, the pin 7 is suspended on the mounting frame 5 by the hanging rope 11, which can effectively prevent the pin 7 from falling and being lost during disassembly or installation, ensuring the normal use of the equipment and reducing downtime and economic losses caused by the loss of the pin.

[0034] Example 2:

[0035] Unlike Embodiment 1, the frame 1 includes two sets of bases 101. The bases 101 are pre-installed on the lifting frame for installing the fabric belt by bolts. The lower ends of the two sets of support frames 102 are connected to the bases 101. The upper end of the support frame 102 is provided with a top mounting frame 103. The top mounting frame 103 is provided with a through hole for the receiving hopper 3 to pass through. The top mounting frame 103 is welded to the receiving hopper 3 or detachably connected by a flange to support the receiving hopper 3.

[0036] In this embodiment, the support frame 102 includes two sets of support plates 104, and the base 101 is disposed between the two sets of support plates 104.

[0037] After the base 101 is installed on the lifting kit, when hoisting this device, it is only necessary to place the base 101 between the two sets of support plates 104 to complete the positioning of the support frame 102, thereby improving hoisting efficiency.

[0038] The base 101 is provided with a fixing plate 105, and the support frame 102 is provided with an ear plate 107 on one side, which is connected to the fixing plate 105 by a pin 106. After the base 101 is installed, the support frame 102 can be installed simply by connecting the ear plate on the support frame 102 to the fixing plate 105.

[0039] In practical use, multiple sets of connection holes can be set along the height of the fixing plate 105. By installing the ear plate 107 in the connection holes at different heights, the overall height of the device can be adjusted.

[0040] Preferably, a climbing frame 108 is provided on the outer side of the support frame 102, which facilitates operators to climb up and down to inspect, maintain and operate the equipment, thereby improving the safety of construction.

[0041] Example 3:

[0042] Unlike Embodiment 1, the lower end of the receiving hopper 3 is provided with a guide cylinder 12, which covers the outside of the receiving hopper 3. The guide cylinder 12 is made of a soft material. In this embodiment, the guide cylinder 12 is made of rubber.

[0043] The guide cylinder 12 can buffer and guide the material when it falls, reduce the impact of the material on the transfer belt 2, prevent material splashing, protect the transfer belt 2, and extend its service life.

[0044] Preferably, the receiving hopper 3 is provided with a scraper 13 on the side near the downstream of the transfer belt 2, and a material passage gap is provided between the scraper 13 and the upper side of the transfer belt 2. By setting the scraper 13, the concrete on the transfer belt can be scraped flat, improving the uniformity of material supply.

[0045] Example 4:

[0046] like Figures 1-4 As shown, when installing the device, the placement of the two sets of bases 101 must first be accurately determined based on the position of the transfer belt 2.

[0047] On the ground, connect the support frame 102 to the receiving hopper 3 and the unloading hopper 4. The lower end of the unloading hopper 4 is fitted inside the receiving hopper 3. Hoist the assembled device onto the lifting frame and connect it to the base 101. Before installation, carefully inspect the ear plate 107 on one side of the support frame 102 and the fixing plate 105 on the base 101 to ensure that both surfaces are flat, free of debris, and that the pin holes are accurately positioned. During installation, precisely align the pin holes of the ear plate 107 and the fixing plate 105. Select a suitable pin 106; the diameter of the pin 106 should fit tightly with the pin hole to ensure a stable connection. Slowly insert the pin 106 into the pin hole until it is fully penetrated. Then, install a matching cotter pin or other anti-loosening device at the end of the pin 106, and pry the cotter pin open to a suitable angle to prevent the pin 106 from loosening and falling off during use. After the connection is completed, check the connection to ensure that the ear plate 107 and the fixing plate 105 fit tightly without any obvious gaps or shaking.

[0048] According to the discharge position of the feeding line 8, rotate the hopper 4 to ensure that the hinge seat 6 on the mounting frame 5 is tightly fitted with the corresponding hinge part on the discharge end truss of the feeding line 8, and the pin 7 completely passes through the pin hole of the two hinge parts. Then, install an anti-loosening device, such as a cotter pin or a locking washer, at the end of the pin 7 to ensure the reliability of the hinge connection.

[0049] After the device is installed and put into use, when the feeding line 8 discharges, the concrete material falls from the discharge hopper 4 into the receiving hopper 3, and then is buffered by the guide cylinder 12 at the lower end of the receiving hopper 3 before falling onto the transfer belt 2. As the pouring height is adjusted, the lifting frame drives the transfer belt 2 to move up and down, and the angle of the feeding line 8 changes. Since the discharge hopper 4 is hinged to the feeding line, it always maintains a proper fit with the discharge end of the feeding line 8, ensuring that the material falls smoothly onto the transfer belt 2.

[0050] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The embodiments and features described in this application can be arbitrarily combined without conflict. The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
