Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a building construction handcart. Background Technology

[0002] On construction sites, handcarts are a common means of transportation, widely used for moving various building materials. Long or irregularly shaped materials, such as steel bars, timber, and pipes, are particularly vulnerable. However, existing handcart designs have some problems, especially when transporting long materials, which can easily lead to instability, wobbling, and even the risk of materials falling off.

[0003] Long, narrow materials are typically longer than the trolley itself, making them prone to tilting or sliding when placed, causing the trolley to lose balance. This is especially true on uneven construction sites, where the trolley is more likely to tilt or wobble, affecting transport stability. Due to the weight and shape of these long materials, workers must constantly maintain the trolley's balance while pushing it, increasing the difficulty and labor intensity of the operation. Particularly during transport, the trolley's wobbling or the material's slippage can lead to worker errors of control, increasing the probability of accidents and potentially causing materials to fall during transport. Falling materials not only increase construction risks but can also damage the surrounding environment, other workers, and equipment, and in severe cases, even affect construction progress and safety. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a construction handcart that can position materials, ensure the stability of long strip materials during transportation, thereby improving construction efficiency and reducing the risk of materials falling.

[0005] In view of this, the present invention provides a construction handcart, comprising:

[0006] The frame has wheels mounted on its underside;

[0007] The carrying bucket, mounted on the chassis, is used to carry building materials;

[0008] Handles are located on both sides of the upper front of the frame;

[0009] The positioning mechanism, installed on the carrying hopper, is used to fix the position of long strip building materials and prevent the materials from sliding or tipping over during transportation;

[0010] The positioning mechanism includes:

[0011] Support plates are installed on the left and right sides of the carrying bucket;

[0012] The slide bar is slidably mounted on the support plate;

[0013] A fixing block is installed at the top of the slide bar;

[0014] The positioning clamp is located between the tops of the two fixed blocks and is positioned above the carrying bucket.

[0015] A return spring is sleeved on the slide rod and positioned between the fixed block and the support plate.

[0016] In the above technical solution, furthermore, the positioning clamp is provided with an extension clamp that slides inside, so as to provide positioning while facilitating the loading of building materials.

[0017] In any of the above technical solutions, a braking mechanism is further provided on the frame, the braking mechanism including:

[0018] Fixing plates are installed on the left and right ends of the lower side of the frame;

[0019] The rotating shaft is rotatably positioned between two fixed plates.

[0020] Support sleeves are located at both ends of the rotating shaft;

[0021] The brake valve is mounted on the support sleeve and is located on the front side of the wheel.

[0022] A pull plate is mounted on the pivot.

[0023] The brake lever is rotated and mounted on the handle.

[0024] The brake cable connects to the brake lever at one end and to the pull plate at the other end.

[0025] The spring is mounted on the pivot and located inside the support sleeve.

[0026] In any of the above technical solutions, a discharge port is further provided on the rear side of the carrying hopper for discharging sand.

[0027] In any of the above technical solutions, further, an auxiliary mechanism for opening and closing the discharge port is provided on the rear side of the carrying hopper, the auxiliary mechanism including:

[0028] The frame is located at the left and right ends of the rear side of the carrying bucket;

[0029] Cylinder, mounted on the frame;

[0030] The baffle is located at the discharge port of the carrying hopper;

[0031] A connecting plate is located on the left and right ends of the rear side of the baffle, and the cylinder piston rod is connected to the connecting plate.

[0032] In any of the above technical solutions, a further feature is provided on the grip: an anti-slip sleeve.

[0033] The beneficial effects of this utility model are:

[0034] 1. Place long strip building materials on the carrying hopper. As the building materials are added, the squeezing positioning clamp moves upward. Through the elastic action of the return spring, the positioning clamp always keeps the building materials clamped. The materials are fixed in the carrying hopper, which can effectively fix the position of the long strip building materials and prevent the materials from sliding or tipping over during transportation, thereby ensuring the stability of the handcart.

[0035] 2. The extension clip can not only help position the material, but also work with the positioning clip to retract during loading, avoiding blocking the loading of long strip materials and keeping them in an appropriate opening state so that the material can be easily placed into the carrying hopper. This achieves material stability while providing space and convenience for transportation, and the operator does not need to frequently adjust the width or position of the positioning clip.

[0036] 3. The operator rotates the brake handle, which drives the brake cable to pull the pull plate. The pull plate acts on the shaft, the spring deforms, and through the support sleeve and brake valve on the shaft, pushes the brake valve to the wheel to contact or rub against it, generating resistance, thereby slowing down the wheel and eventually stopping it, preventing the handcart from sliding freely on slopes or uneven ground, and ensuring the stability of the handcart.

[0037] 4. The discharge port allows materials such as sand and soil to be discharged smoothly through the rear opening without tilting the entire handcart or tilting it too much. This reduces the labor intensity of operators, improves the convenience of unloading, and is suitable for various working scenarios, such as confined spaces or places with other equipment obstacles.

[0038] 5. Before unloading, the baffle at the discharge port is closed to prevent material leakage. When discharge is required, the piston rod of the cylinder will push the connecting plate, causing the connecting plate to move the baffle, thereby opening the discharge port. The material (such as sand or soil) will flow out naturally by gravity. This enables precise control of the discharge port, allowing the material to be discharged at a precise speed and quantity, avoiding errors and waste caused by manual operation.

[0043] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0044] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0045] Example 1:

[0046] like Figures 1-3 As shown, this embodiment provides a construction handcart, including:

[0047] The frame 1 has wheels 2 on its underside;

[0048] The carrying bucket 3, mounted on the frame 1, is used to carry building materials;

[0049] Handles 4 are located on both sides of the upper front end of the frame 1;

[0050] Positioning mechanism 5, installed on the bearing bucket 3, is used to fix the position of long strip building materials and prevent the materials from sliding or tipping over during transportation;

[0051] The positioning mechanism 5 includes:

[0052] Support plates 51 are installed on the left and right sides of the bearing bucket 3;

[0053] The slide bar 52 is slidably mounted on the support plate 51;

[0054] The fixing block 53 is located at the top of the slide bar 52;

[0055] The positioning clamp 54 is located between the tops of the two fixing blocks 53 and is positioned above the bearing bucket 3;

[0056] The return spring 55 is sleeved on the slide rod 52 and positioned between the fixed block 53 and the support plate 51.

[0057] In this technical solution, the operator first pushes the handcart to the desired transport position, then places the long strip of building material on the carrying hopper 3. As the building material is added, the compression positioning clamp 54 moves upward. The positioning clamp 54 drives the fixing block 53 to slide on the support plate 51 via the slide rod 52, and the return spring 55 is stretched. Through the elastic action of the return spring 55, the positioning clamp 54 always keeps the building material clamped, and the material is fixed in the carrying hopper 3. After the building material is loaded, the positioning clamp 54 prevents the material from sliding or tilting during transport. The operator controls the direction of the handcart by holding the handle 4. The wheels 2 under the frame 1 provide stable support and flexible driving ability, allowing the operator to smoothly push the handcart for transport. After reaching the destination, the operator can park the handcart in an appropriate position. With a slight manipulation, the fixing block 53 moves the sliding rod 52 upward, simultaneously causing the positioning clamp 54 to move upward. The return spring 55 is stretched, moving the positioning clamp 54 to the appropriate position. The elongated building material can then be easily unloaded. The operator can then remove the building material from the carrying hopper 3 and place it at the desired unloading location. After unloading, the operator releases the fixing block 53. Under the reset action of the return spring 55, the fixing block 53 moves the positioning clamp 54 downward to reset. The return spring 55 of the positioning mechanism 5 returns the sliding rod 52 and positioning clamp 54 to their initial state, ready for the next use. The operator can then quickly clean up and prepare the handcart for the next material transport. This effectively secures the position of long, narrow building materials, preventing them from sliding or tipping over during transport and ensuring the stability of the trolley. Simultaneously, the positioning clamp 54 can be adjusted according to the increasing number of materials, ensuring that all building materials are transported securely. This makes the use of trolleys for transporting long, narrow building materials safer, more stable, and more flexible, significantly improving construction efficiency and reducing the risk of accidents, thus demonstrating broad application prospects.

[0058] like Figure 1 and Figure 2As shown, in this embodiment, the positioning clip 54 is optimized by having an extension clip 6 slidably provided inside, so as to provide positioning while facilitating the loading of building materials.

[0059] In this technical solution, the extension clamp 6 not only helps position the material but also works in conjunction with the positioning clamp 54. During loading, the extension clamp 6 can retract, preventing obstruction of long, narrow materials. The design of the extension clamp 6 allows the positioning clamp 54 of the handcart to remain in an appropriate open position during loading, enabling operators to easily place materials into the carrying hopper 3. This avoids operational difficulties caused by the inability of the clamp to expand or the opening being too small in traditional designs. After the building materials are placed, the extension clamp 6 is pulled out, increasing the positioning width of the positioning clamp 54 and enabling more stable positioning of the building materials. When unloading the building materials is required, the extension clamp 6 is retracted, allowing the operator to remove the materials. This achieves material stability while providing space and convenience for transportation. Operators do not need to frequently adjust the width or position of the positioning clamp 54, enabling material loading and fixing to be completed in one go, greatly improving construction efficiency and reducing manpower input.

[0060] Example 2:

[0061] This embodiment provides a construction handcart, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0062] like Figure 1 and Figure 2 As shown, in this embodiment, the optimized design includes a braking mechanism 7 on the frame 1, the braking mechanism 7 comprising:

[0063] The fixing plate 71 is located on the left and right ends of the lower side of the frame 1;

[0064] The rotating shaft 72 is rotatably disposed between the two fixed plates 71;

[0065] Support sleeves 73 are located at the left and right ends of the rotating shaft 72;

[0066] Brake valve 74 is mounted on support sleeve 73 and is located on the front side of wheel 2.

[0067] Pull plate 75 is mounted on pivot 72;

[0068] The brake handle 76 is rotatably mounted on the grip 4;

[0069] Brake cable 77, one end is connected to brake handle 76, and the other end is connected to pull plate 75;

[0070] The spring 78 is mounted on the pivot 72 and located inside the support sleeve 73.

[0071] In this technical solution, the brake mechanism 7 is initially in the unlocked state, allowing the wheel 2 to rotate freely. At this time, the handcart can move normally, and the operator controls the direction of the handcart via the handle 4, pushing it to the desired parking or transport location. When it is necessary to stop the handcart or use it on a slope, the operator rotates the brake handle 76. The brake handle 76 connects to the brake cable 77, which pulls the pull plate 75. The pull plate 75 acts on the rotating shaft 72, causing the spring 78 to deform. Through the support sleeve 73 on the rotating shaft 72 and the brake valve 74, the brake valve 74 is pushed to the front of the wheel 2. At this point, the brake valve 74 contacts or rubs against the wheel 2, generating resistance, which slows the wheel 2 down and eventually stops it. The contact force between the brake valve 74 and the wheel 2 varies depending on the degree of rotation of the brake handle 76. When the operator rotates the brake handle 76, the brake valve 74 of the braking system can contact the wheel 2 more tightly, thus achieving a stronger braking effect. The braking system effectively prevents the handcart from sliding freely on slopes or uneven surfaces, ensuring its stability. When it's time to continue transporting or moving the handcart, the operator simply returns the brake handle 76 to its original position, releasing the brake cable 77. Under the resetting action of the spring 78, the shaft 72 drives the pull plate 75 back to its original position. Simultaneously, the shaft 72 resets the support sleeve 73 and brake valve 74, allowing the wheels 2 to rotate freely again, and the handcart can continue to move normally. When parking, the operator uses the brake handle 76 again to apply the brake, ensuring the handcart will not slide due to ground slope or other external forces while stationary, ensuring safe parking. The braking mechanism 7 automatically remains locked until the operator manually releases the brake or continues using the handcart. This timely and effective braking prevents the handcart from sliding or tilting due to ground slope or external interference, making it particularly suitable for sloping construction sites or uneven surfaces.

[0072] Example 3:

[0073] This embodiment provides a construction handcart, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0074] like Figure 2 As shown, in this embodiment, the optimized design includes a discharge port 8 on the rear side of the carrying hopper 3 for discharging sand.

[0075] In this technical solution, the discharge port 8 allows materials such as sand and soil to be smoothly discharged through the rear opening without tilting the entire wheelbarrow or tilting it excessively. This reduces the labor intensity of operators and improves the convenience of unloading. Since operators only need to open the discharge port 8, the sand will flow out naturally, reducing unloading time and significantly improving work efficiency compared to traditional dumping methods. Traditional unloading methods usually require tilting the wheelbarrow, which may result in sand waste due to incorrect dumping angles. By setting the discharge port 8, sand can be discharged more precisely, avoiding unnecessary losses. The design of the discharge port 8 is suitable for various working scenarios, such as confined spaces or places with other equipment obstacles, allowing operators to complete the unloading work without moving the wheelbarrow or tilting it significantly. This design reduces the sand flying phenomenon that may occur during the tilting of the wheelbarrow, thereby reducing the impact of dust on the environment, especially in outdoor construction or relatively enclosed environments, where it has significant advantages.

[0076] like Figure 2 and Figure 3 As shown, in this embodiment, an optimized auxiliary mechanism 9 for opening and closing the discharge port 8 is provided on the rear side of the carrying hopper 3. The auxiliary mechanism 9 includes:

[0077] The frame 91 is located at the left and right ends of the rear side of the carrying bucket 3;

[0078] Cylinder 92 is mounted on frame 91;

[0079] Baffle 93 is located at the discharge port 8 of the carrying hopper 3;

[0080] The connecting plate 94 is located on the left and right ends of the rear side of the baffle 93, and the piston rod of the cylinder 92 is connected to the connecting plate 94.

[0081] In this technical solution, the operator pushes the handcart to the designated unloading location and ensures that the carrying hopper 3 is loaded with material (such as sand, soil, etc.). Before unloading, the baffle 93 of the discharge port 8 is closed to prevent material leakage. The operator activates cylinder 92, and the piston rod of cylinder 92 pushes connecting plate 94, causing connecting plate 94 to move baffle 93, thereby opening discharge port 8. The opening of baffle 93 can be adjusted by the stroke of cylinder 92 according to the required unloading volume, controlling the opening degree of baffle 93, thus achieving precise control of material flow. When discharge port 8 is fully open, the material (such as sand, soil) will flow out naturally by gravity. The discharge speed and flow rate of the material can be effectively controlled according to the opening degree of baffle 93. If slow discharge is required, the operator can adjust the working state of cylinder 92 to reduce the opening degree of baffle 93, thereby slowing down the discharge speed. Once material discharge is complete, the operator can reverse the direction of cylinder 92, retracting the piston rod to bring connecting plate 94 back to its original position and close baffle 93. At this point, discharge port 8 is completely closed, ensuring that material no longer flows out, avoiding waste and unnecessary leakage. This allows for precise control of discharge port 8, enabling material to be discharged at a precise speed and quantity, avoiding errors and waste from manual operation.

[0082] The grip 4 is equipped with an anti-slip sleeve 10.

[0083] In this technical solution, the anti-slip sleeve 10 increases the friction of the handle 4 through its special material and surface texture (such as rubber, silicone, or soft plastic), allowing operators to firmly grip the handle 4 even in wet, dirty, or sweaty environments, reducing the risk of hand slippage. The anti-slip sleeve 10 not only improves the stability of the handle 4 but also provides better feel and comfort, reducing fatigue and wear caused by prolonged contact between the palm and the handle 4 during cart pushing. Especially in high-intensity construction environments, the anti-slip sleeve 10 can effectively distribute hand pressure, reducing discomfort from excessive hand stress. On construction sites, carts need to be moved frequently and may encounter uneven ground or obstacles. In these situations, the anti-slip sleeve 10 ensures that the operator's hands are firmly fixed on the handle 4, preventing the cart from becoming uncontrollable or causing accidents due to hand slippage, thus enhancing overall operational safety. As a protective layer, the anti-slip sleeve 10 reduces direct friction between the handle 4 and the hand, preventing wear or aging of the handle 4 surface during prolonged use and extending the lifespan of the cart. The material of the anti-slip sleeve 10 can be selected according to the needs of the construction environment. For example, in humid environments, waterproof and corrosion-resistant rubber or silicone anti-slip sleeves 10 can be used; in high-temperature or cold environments, high-temperature and low-temperature resistant materials can be selected to ensure that the handcart provides a good handling experience under various climatic conditions.

[0084] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
