Description

Technical Field

[0001] This utility model relates to the field of cement transportation technology, specifically a protective device for cement transportation and storage. Background Technology

[0002] With the continuous development of society, the construction industry has also developed rapidly. As urban infrastructure continues to improve, the construction industry has gained better development opportunities. Cement is an essential industrial product in the construction industry. During the transportation and storage of cement, protective devices are required, as follows.

[0003] A search revealed a patent document with authorization announcement number CN213565972U, which discloses a protective device for cement transportation and storage. The device includes a base plate, with its top left and right ends fixedly connected to the bottom of a set of vertical plates. The tops of the vertical plates are fixedly connected to the left and right sides of the bottom of a top plate, and the top of the top plate is fixedly connected to the bottom of a push rod. The center of the bottom of the top plate is fixedly connected to the top of a limiting plate, and two sets of arc-shaped columns are provided below the limiting plate. This protective device for cement transportation and storage, by incorporating a push rod and rollers, facilitates movement and improves its practicality. The rollers, roller axles, wheel supports, and L-shaped rods work together to retract and extend the rollers, preventing movement during transportation. A linkage mechanism formed by a rotating rod, a positioning rod, and wheel supports ensures that the linkage mechanism creates a fixed point when the rollers are retracted or extended, improving the stability of the device.

[0004] However, the aforementioned patents still have the following areas for improvement:

[0005] 1. Because both sides of its two vertical plates are open, there is no front and rear limiting mechanism for the cement bag. Therefore, the cement bag is still prone to slipping and falling during transportation and transfer.

[0006] 2. Although it is equipped with adsorption blocks to adsorb cement dust and effectively prevent it from spreading and polluting the surrounding environment, the adsorbed cement dust cannot be recycled and reused, which will result in the waste of some cement resources and increase the loss during cement transportation. Utility Model Content

[0007] The purpose of this utility model is to provide a protective device for cement transportation and storage, in order to solve the problem of the above-mentioned patent, which has an open design on both the front and back sides of its two vertical plates and does not have a front and back limiting mechanism for cement bags. Therefore, cement bags are still prone to slipping and falling during the transportation and transfer process. Although it is equipped with adsorption blocks to adsorb cement dust and effectively prevent it from spreading and polluting the surrounding environment, the adsorbed cement dust cannot be recycled and reused, which will cause some cement resources to be wasted and increase the loss problem during cement transportation.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a protective device for cement transportation and storage, comprising a base, a plurality of casters with braking mechanisms fixedly installed at the bottom of the base, two vertical plates fixedly installed at the top of the base, the two vertical plates being close to the two sides of the base respectively, a top seat fixedly installed between the two vertical plates, the top seat being close to the top of the two vertical plates, two sets of through-hole limiting grooves being opened inside the base, the two sets of limiting grooves being close to the front and rear sides of the base respectively, detachable limiting mechanisms fixedly installed at the front and rear sides of the two vertical plates, a dust collection mechanism fixedly installed at the top of the top seat, the bottom of the dust collection mechanism extending through the top seat to below the top seat.

There are four locking seats, which are respectively fixedly installed on the front and rear sides of the two vertical plates. The top and one side of the locking seat are open. The inside of the locking seat is provided with a locking groove. A first magnet is fixedly attached to the bottom surface of the locking groove. There are two locking strips. The two ends of the locking strip are respectively matched and engaged with the two locking grooves. Two second magnets are fixedly attached to the bottom of the locking strip, and the two second magnets are respectively attracted and connected to the two first magnets. Multiple limiting rods are fixedly connected to the bottom of the locking strip.

[0011] Preferably, the mounting base, mounting strip, and limiting rod are all made of aluminum alloy, and the bottom ends of the multiple limiting rods respectively pass through multiple limiting grooves.

[0012] Preferably, the spacing between adjacent limiting rods is the same, and the spacing between adjacent limiting rods is 10cm-15cm.

[0013] Preferably, the dust collection mechanism includes a battery, a dust collection box, and an exhaust fan. The battery is fixedly installed on the top of the top base. There are two dust collection boxes and two exhaust fans. The two dust collection boxes are fixedly installed on the top of the top base and located on both sides of the battery. A door is hinged to one side of the dust collection box. When closed, the door is sealed to the dust collection box. A filter screen is installed inside the dust collection box. A T-shaped dust collection pipe is connected to one side of the dust collection box. The two ends of the T-shaped dust collection pipe away from the dust collection box are closed.

[0014] This utility model provides a protective device for cement transportation and storage, which has the following beneficial effects:

[0015] (1) This utility model has a detachable limiting mechanism, which allows the two clamping strips and two sets of limiting rods to be removed together when transporting cement. Then, multiple cement bags can be stacked and loaded onto the base in sequence and positioned between the two vertical plates. After loading, the two clamping strips and two sets of limiting rods can be reset and installed. After reset and installation, the two vertical plates can limit the multiple cement bags to the left and right during the transportation and transfer of multiple cement bags. At the same time, the two clamping strips and two sets of limiting rods can limit the multiple cement bags to the front and back. Therefore, it can effectively prevent cement bags from falling or slipping during transportation and affecting the normal transportation and transfer work. It has high practicality.

[0016] (2) By setting up a dust collection mechanism, this utility model enables the use of two exhaust fans in conjunction with two dust collection boxes to generate suction at two sets of dust collection hoods during the loading and transportation of cement bags. This suction draws the cement dust generated during the loading and transportation of cement bags into the dust collection boxes, where it is intercepted and filtered by the filter screen and retained in the dust collection boxes for centralized collection. This not only effectively prevents cement dust from polluting the surrounding environment, but also allows for the opening of the dust collection box door after the subsequent transportation and transfer work is completed, enabling centralized cleaning and secondary recycling of the cement dust collected inside the dust collection box. This greatly reduces the loss during cement transportation and further improves the practicality of the device. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figure 1-5 As shown, this utility model provides a technical solution: a protective device for cement transportation and storage, including a base 1, a plurality of casters 2 with braking mechanisms are fixedly installed at the bottom of the base 1, two vertical plates 3 are fixedly installed at the top of the base 1, and the two vertical plates 3 are respectively close to the two sides of the base 1, a top seat 4 is fixedly installed between the two vertical plates 3, the top seat 4 is close to the top of the two vertical plates 3, two sets of through limiting grooves 5 are opened inside the base 1, and the two sets of limiting grooves 5 are respectively close to the front and rear sides of the base 1, detachable limiting mechanisms 6 are fixedly installed at the front and rear sides of the two vertical plates 3, and a dust collection mechanism 7 is fixedly installed at the top of the top seat 4, the bottom of the dust collection mechanism 7 extends through the top seat 4 to the bottom of the top seat 4.

[0025] Push handles 8 are provided on the sides of the two vertical plates 3 that are far apart from each other, and the two push handles 8 are located on the upper half of the two vertical plates 3 respectively, so that the push handles 8 can be used in conjunction with multiple casters 2 to push the device to move and transfer.

[0026] The detachable limiting mechanism 6 includes a mounting base 601 and mounting strips 602. Four mounting bases 601 are provided, fixedly installed on the front and rear sides of the two vertical plates 3 respectively. The top and one side of the mounting base 601 are open-type designs. The interior of the mounting base 601 has a mounting groove 603, with a first magnet 604 fixedly attached to the bottom surface of the groove. Two mounting strips 602 are provided, with both ends of each strip engaging with the two mounting grooves 603. Two second magnets 605 are fixedly attached to the bottom of each strip, and the two second magnets 605 are respectively attracted to the two first magnets 604. Multiple limiting rods 606 are fixedly connected to the bottom of each strip. When transporting cement, the two mounting strips 602, along with the two sets of limiting rods 606, are first lifted until the second magnets 605 separate from the first magnets 604, thus allowing the cement to be transported. The clamping strip 602, along with the two sets of limiting rods 606, can be removed. At this point, multiple cement bags can be stacked and loaded onto the base 1 in sequence, positioned between the two vertical plates 3. After loading, the two clamping strips 602 and the two sets of limiting rods 606 are reset and installed. During resetting and installation, the two sets of limiting rods 606 are aligned with the two sets of limiting grooves 5, and the clamping strip 602 is engaged with the clamping groove 603 until the second magnet 605 is attracted and connected to the first magnet 604. This completes the resetting and installation of the clamping strip 602 and the limiting rods 606. In this way, during the subsequent transportation and transfer of multiple cement bags, the two vertical plates 3 limit the multiple cement bags to the left and right, while the two clamping strips 602, in conjunction with the two sets of limiting rods 606, limit the multiple cement bags to the front and back. Therefore, it can effectively prevent cement bags from falling or slipping during transportation, thus avoiding affecting the normal transportation and transfer work.

[0027] The mounting base 601, mounting strip 602, and limiting rod 606 are all made of aluminum alloy. The bottom ends of the multiple limiting rods 606 pass through multiple limiting grooves 5. The mounting base 601, mounting strip 602, and limiting rod 606 made of aluminum alloy have high rigidity and are not easily deformed or damaged. The bottom ends of the multiple limiting rods 606 passing through multiple limiting grooves 5 can effectively improve the stability of the limiting rods 606, making them less likely to be displaced or deformed due to the squeezing of the cement bag.

[0028] The spacing between adjacent limit bars 606 is the same, and the spacing between adjacent limit bars 606 is 10cm-15cm, which can effectively intercept multiple cement bags from sliding and falling.

[0029] The dust collection mechanism 7 includes a battery 701, a dust collection box 702, and an exhaust fan 703. The battery 701 is fixedly installed on the top of the top base 4. There are two dust collection boxes 702 and two exhaust fans 703. The two dust collection boxes 702 are fixedly installed on the top of the top base 4 and are located on both sides of the battery 701. A door 704 is hinged to one side of the dust collection box 702. When closed, the door 704 is sealed to the dust collection box 702. The interior of the dust collection box 702 is movable. A filter screen 705 is installed in the dust collection box 702. A T-shaped dust collection pipe 706 is connected to one side of the dust collection box 702. The two ends of the T-shaped dust collection pipe 706 away from the dust collection box 702 are closed. Multiple branch pipes 707 are connected to the bottom of the dust collection pipe 706. The bottom of the branch pipes 707 extends through the top seat 4 to the bottom of the top seat 4. The bottom of the branch pipes 707 is connected to a dust collection hood 708. An exhaust fan 703 is fixedly installed on the top of the dust collection box 702, and the exhaust end of the exhaust fan 703 is connected to... The duct is connected to the side of the dust collection box 702 away from the dust collection pipe 706. The exhaust fan 703 is electrically connected to the storage battery 701, so that during the loading and transportation of cement bags, the storage battery 701 can supply power to the two exhaust fans 703. Then, the operation of the two exhaust fans 703, in conjunction with the two ducts, two dust collection boxes 702, two dust collection pipes 706 and two sets of branch pipes 707, generates suction at the two sets of dust collection hoods 708, thereby drawing the cement dust generated during the loading and transportation of cement bags into the dust collection box 702. The dust is then intercepted and filtered by the filter plate 705 and retained in the dust collection box 702 for centralized collection. This not only effectively avoids cement dust pollution of the surrounding environment, but also allows for the opening of the box door 704 at the dust collection box 702 after the subsequent transportation and transfer work is completed, enabling centralized cleaning and secondary recycling of the cement dust collected inside the dust collection box 702, greatly reducing the loss during cement transportation.

[0030] Working principle: When transporting cement, first lift the two clamping strips 602 together with the two sets of limiting rods 606 until the second magnet 605 separates from the first magnet 604. Then, remove the two clamping strips 602 together with the two sets of limiting rods 606. At this point, multiple cement bags can be stacked and loaded onto the base 1 in sequence, positioning them between the two vertical plates 3. After loading is complete, reset and reinstall the two clamping strips 602 together with the two sets of limiting rods 606. At this time, align the two sets of limiting rods 606 with the two sets of limiting slots 5 respectively, and make the locking strip 602 engage with the locking slot 603 until the second magnet 605 is attracted and connected to the first magnet 604. This completes the reset and installation of the locking strip 602 and the limiting rods 606, so that during the subsequent transportation and transfer of multiple cement bags, the two vertical plates 3 can limit the left and right movement of multiple cement bags. At the same time, the two locking strips 602, together with the two sets of limiting rods 606, can move the multiple cement bags forward. The rear limit switch effectively prevents cement bags from falling or slipping during transportation, thus avoiding disruption to normal transport and transfer operations. During loading and transport, the battery 701 powers two exhaust fans 703. These fans, in conjunction with two ducts, two dust collection boxes 702, two dust collection pipes 706, and two sets of branch pipes 707, generate suction at the two dust collection hoods 708. This suction draws cement dust generated during loading and transport into the dust collection boxes 702, where it is filtered and retained by the filter screen 705 for centralized collection. This not only effectively prevents cement dust from polluting the surrounding environment but also allows for subsequent cleaning and recycling of the collected cement dust after transport and transfer, significantly reducing losses during cement transportation.
